LONDON PREVIEW DAILYNEWS PETEX 2014 Conference & Exhibition CELEBRATING 25 YEARS, 1989 - 2014 OFFICIAL SHOW DAILY PUBLISHER OF PETEX 2014 Welcome to PETEX Show marks 25 years of technological developments and industry advances. By oliver quinn, ophir energy t is with great pleasure that I welcome you all to PETEX 2014, our largest conference and exhibition to date. 2014 Icontinues to see change and innovation at PETEX, includ- ing a move east to our new home at the ExCeL conference venue. The pending redevelopment of Earls Court leaves a paucity of large exhibition space in central London, and with the recent growth of PETEX the larger ExCeL site allows for a comfortable space and even more room to expand. The new venue represents a change in character and neighborhood but still retains the key facilities characteristic of a successful PETEX. The 2014 conference is a significant milestone in PETEX history, representing 25 years since the first event in 1989. The event has come a long way from those early beginnings and is now a key E&P meeting on both the U.K. and international calendar, attracting more than 3,500 attendees in 2012 with a world-class technical program and leading industry exhibitors.This year again sees a wide range of events anchored around an incredibly strong series of presentations covering topics as diverse as African exploration and the lat- est developments in 4-D seismic. 2014 also sees the return of the popular 3-D Visualization Theater showcasing breaking software and technology developments. The final day of the conference sees the introduction of a new event, the PETEX Forum, a question time-style interactive debate centered around the technical aspects and feasibility of developing U.K. shale gas. While the environmental, social and political issues are paramount in the future story of U.K. unconventionals PETEX provides a great forum to debate, within the subsurface community, the geological and drilling opportunities and challenges. As always, the conference provides a packed social agenda from the cocktail party on Tuesday night, to the pub crawl Wednesday and the Sundowner event on Thursday. These events are only possible through the generous support of our sponsors and exhibitors, so a big thank you goes to them. Last, but by no means least, I would like to thank the many volunteers composing the organizing and technical committees as well as the Petroleum Exploration Society of Great Britain office staff for their dedication and hard work in ensuring PETEX 2014 is a fitting legacy for that first event 25 years ago! n Knowledge Sweet Spots are Focus of Technical Program International theme spotlights developments in emerging plays. By ricki CHarles, shell 2014 sees me reprise the role of chairman of the technical committee. I must start by expressing my sinPcereETEX thanks to the volunteer members of the committee, without who’s support the program would not be the most extensive to date. Indeed, in addition to the core technical program on Tuesday and Wednesday, we have the PETEX Forum on Thursday morning, the PETEX seminars on Thursday afternoon with the 3-D Visualization Theater and oral poster program across three days. The Wednesday program will see five parallel technical streams, plus the Post-graduate Research Collaboration Showcase. 2014 marks a significant milestone for a number of reasons. For the industry as a whole, we have celebrated the 50th anniversary of the first U.K. Seaward License Round. Even back in those sensational days of the huge discoveries in the 1970s and 1980s, I am sure few people would have predicted the basin to still be producing today, let alone in 2030. Members of the Petroleum Exploration Society of Great Britain (PESGB) will also be well aware that we celebrate the 50th anniversary of the society this year, and PETEX itself reaches its 25th birthday. It’s a real privilege to be able to contribute in this really important year. As a team, the committee has aspired to deliver a technical program that would appeal across the PESGB membership.We have designed the program to be current and topical, encompassing a variety of themes ranging from frontier exploration to the latest developments in existing basins. Once again this year, the unifying theme is enabling technology, and we hope the program will encourage knowledge-sharing and a cross-fertilization of ideas that will be beneficial to you and your organizations. Over the course of recent PETEX events, there has been a deliberate move to internationalize the technical program, reflecting the reality that many of our U.K.-based friends and colleagues are increasingly focused on a globally diverse portfolio of assets and interests. The program this year continues to develop this international flavor with thematic sets on emerging plays on both West and East African margins, Newfoundland and Nova Scotia, and underexplored areas in the Arctic region.

CO M al GlobERGY AL REGIONRT: REPO T AS SOUTHEASIA EN ce penden in inde dawn A new PETEX – More Than Just a Technical Event A number of social events have been organized alongside the technical presentations and exhibition at PETEX 2014. Contributed by PETEX P ETEX is widely regarded as a first-class technical conference and exhibition. Over the years, it has become a must-attend event for geoscientists working in the hydrocarbon basins of Europe, the North Atlantic and Africa, who want to keep abreast of current exploration thinking and techniques. But it is more than that. It is also a valuable networking event where like-minded people gather to discuss the upstream industry at large and seek solutions for some of the complex technical issues that affect the day-to-day working life of the modern explorationist or production geoscientist. The PETEX organizing committee feels strongly that PETEX should be seen as a social, as well as a technical, event. Part of the purpose of PETEX is to stimulate the cross-fertilization of ideas. The committee considers that, as a result, the industry will become better informed and culturally stronger. There has been a long tradition at PETEX of seeking opportunities for delegates to network.This PETEX is no exception, and it is with that purpose in mind that a number of social events have been organized alongside the technical presentations and exhibition. On Tuesday evening at the end of the first day of the conference, the cocktail party is scheduled to take place. This is a reception with canapés held in the exhibition hall between 5 p.m. and 7:30 p.m. following the close of the technical session, while the exhibition remains open. It is open to all PETEX attendees and provides delegates with the opportunity to tour the booths in convivial surroundings and talk to exhibitors—something they might not otherwise do if the draw of the technical session during the day is too great to resist. Since many of the exhibitors are presenting technical papers, a visit to the exhibition often will give delegates the chance to discuss content seen during the day with the authors or to follow up on technology outlined in the many case studies. As an additional incentive to meet delegates, many exhibitors support the evening by providing refreshments at their booths.

COntributed by CGG lthough the central North Sea is a mature basin, it is still rich in opportunities for the development and A discovery of new fields, as the area is notoriously chal- lenging for seismic imaging, especially in the deep, HP/ HT part of the Central Graben. However, the company’s extensive Cornerstone dataset benefits from a portfolio of new technology to address these imaging challenges, creating new opportunities. The entire volume has been enhanced to capitalize on recent developments in broadband technology, velocity modeling and demultiple techniques. Recent phases of acquisition have used BroadSeis variable-depth streamers and the BroadSource broadband source, delivering ghost-free data with more than six octaves of bandwidth. With four octaves of signal below 40 Hz, BroadSeis provides the best resolution for imaging below the base Cretaceous unconformity. Combining BroadSeis with BroadSource also delivers high frequencies up to the sampling Nyquist frequency for incredible resolution of shallow channels and geohazards. Advanced ghost wavefield elimination has been applied to the legacy Cornerstone data to extend the bandwidth as near as possible to the new BroadSeis data, so that they can be merged to create a contiguous broadband prestack depthmigrated (PSDM) dataset. The bandwidth achievable depends on the signal-tonoise ratio in the recorded data, so the ultralow frequencies of BroadSeis true broadband data cannot be obtained. Nevertheless, considerable improvements have been delivered, providing a 35,000-sq-km (13,513-sq-mile) broadband PSDM dataset. Comparison of new regional Cornerstone PSDM data with previous locally tailored data is shown. (Image courtesy of CGG) ION. Delivering solutions through innovation.

Driven to solve.™ 4 ION-1490_CorporateBrand_PETEX.indd 1 New demultiple techniques, such as model-based water-layer demultiple and internal multiple modeling, have been applied to this dataset and deliver vast reductions in the multiple contamination that has historically afflicted central North Sea datasets. Large-scale Quaternary channeling in the near surface strongly influences the imaging of deeper data. Recent advances in full-waveform inversion and dip-constrained tomography have enabled highly detailed velocity models to be built incorporating these channels, resulting in more accurate imaging of deeper events. There are also complex structures with strong velocity contrasts found here, often located at great depths, where limitations of available data might restrict velocity and anisotropy modeling. Multilayer tomography (TomoML) brings stability and accuracy to velocity modeling in such areas, producing more geologically plausible models and providing improved imaging results. Applying these techniques to the entire Cornerstone dataset with extensive well control has produced a regional anisotropic PSDM dataset with better local detail and definition than previous proprietary datasets tailored to specific local targets. The new east-west-oriented Cornerstone Phase 8 BroadSeis-BroadSource survey overshoots the existing conventional long-offset, north-south-oriented data. This new survey has been combined with the reprocessed earlier data to provide a dual-azimuth volume over the HP/ HT area of the Central Graben, with all the inherent benefits of dual-azimuth data: increased sampling, options to apply true 3-D processing algorithms for better noise and multiple attenuation, improved illumination beneath the base Cretaceous, and optimal imaging of subtle features such as four-way closures due to more accurate velocity and anisotropy models. The dataset shows significant improvements in imaging below the base Cretaceous unconformity and might indicate the future path of North Sea acquisition. In addition to the best-quality seismic data, CGG also provides advanced, value-added pore pressure prediction (PPP) and Facies Finder products over Cornerstone to aid the understanding of existing and potential new reservoirs. PPP provides volumetric estimates of pore pressure across the deep part of the Central Graben to identify potential drilling hazards and improve well positioning. CGG combines expertise in high-resolution seismic velocities, petrophysical modeling and well data integration to deliver a range of seismic pore pressure services. This is available over about 15,215 sq km (5,874.5 sq miles) of potential HP/HT data in the Central Graben. Facies Finder maximizes the value of seismic data early in the E&P cycle to highlight and de-risk potential prospects. It provides easy-to-interpret prestack attribute volumes for lithology and fluid identification using a relative elastic inversion requiring no well calibration, so it is suitable for exploration and screening for amplitude-vs.offset anomalies. The reprocessed merged Cornerstone dataset delivers an unprecedented volume of high-quality anisotropic broadband PSDM data over a huge area of the Central Graben of the central North Sea, including the HP/HT area. This regional dataset is available now, delivering the local detail required to assess new license awards, complemented by Facies Finder over the whole dataset and PPP data over the HP/HT areas. n P R E V I E W | NOV. 18, 2014 | E&P DAILY NEWS 10/8/14 10:01 AM Advanced Seismic Solutions for Reducing Exploration Costs Seismic workflow technology can accelerate project turnaround while optimizing decision-making around geological and project constraints. COntributed by polarcus is money, and in a fast-moving world the pressure to make quick and accurate decisions on key exploraTtionime milestones is greater than ever. Polarcus’ RightFLOW can seamlessly integrate and accelerate every step of the seismic data acquisition and processing workflow. This includes everything from the initial survey design to the delivery of final data products, with the technology able to tailor the workflow for any given geologic and geophysical environment. The result will enable users to make more informed decisions about potential well commitments earlier in the exploration cycle. This latest Polarcus offering is the result of a data processing collaboration between Polarcus and DownUnder GeoSolutions (DUG) that has taken a fresh look at the entire seismic workflow. The partnership combines the survey design and acquisition expertise at Polarcus with the processing and imaging expertise at DUG. As a result of that collaboration Polarcus is deploying DUG’s Insight software system onboard its fleet of high-end 3-D seismic vessels.The software system is powered by SGI-engineered hardware, which will enable the company to offer companies a processing flow designed in conjunction with each companies’ own experts to address both the specific geological objectives and the critical timelines for the project. At the core of any offering will be onboard quality-control (QC) flows to ensure that seismic data are recorded well within the tolerance specifications set by the user. Key modules have been specified by Polarcus’ own field geophysicists and designed by DUG software engineers to ensure that a full suite of quality-control products are produced in real time on a line-by-line basis and offline during the course of acquisition to monitor surveywide seismic data quality and temporal and spatial continuity. A significant component of the onboard processing flow real-time software environment is interactive and intuitive, meaning no scripts are required for onboard QC or processing. The offline processing toolkit has been specifically designed to allow production of full-fold migrated 3-D volumes, incorporating a suite of multichannel noise attenuation techniques including shallowwater demultiple, 3-D surface related multiple elimination, highly interactive velocity picking and quality control, Voronoi area regularization, and prestack time migration. The offering can itself be structured in different ways to suit individual user requirements including comprehensive onboard acquisition quality control followed by full onAs the result of a data processing collaboration, DUG’s Insight software system will be deshore processing; ultrafast advanced ployed onboard Polarcus’ fleet of high-end 3-D seismic vessels.

COntributed by TGS continues to invest substantial sums in its multiclient geoscience data in the Barents Sea, both in terms of TnewGS data acquisition and also reprocessing of existing data. TGS has acquired more than 177,000 km (109,983 miles) of its Norway Barents Sea Renaissance (NBR) 2-D data and also in excess of 28,000 sq km (10,811 sq miles) of its Hoop Fault (HF) Complex and Finnmark Platform 3-D surveys. Since the discovery of relatively shallow oil in the Wisting well (7324/8-1) by OMV and partners last year, the demand for high-resolution data has grown. Recent reprocessing Broadband processing of conventionally acquired seismic data has become commonplace over the last few years, and TGS has taken the opportunity to use its Clari-Fi technology to improve the resolution of its data. In addition, a short offset, high-resolution volume, with sampling at 2 ms and a bin size of 6.25 m (20.5 ft) also was produced.

The dataset was a mixture of six small 3-D surveys ranging in size from 18 sq km to 185 sq km (7 sq miles to 71 sq miles), plus three 2-D swaths that wandered between areas of potential interest. The data received from the field crew were in SEG-Y format where the trace coordinates and offsets had been calculated and put in the headers. The coordinates were calculated by using the GPS positions of the buoys and the shape of the cross cable (assumed to be a catenary). The processing of the P-Cable data went through a fairly conventional Clari-Fi route consisting of resample to 1 ms, debubble from a data-derived source wavelet, swell noise attenuation, deghosting, 4-D anti-leakage regularization, FXY deconvolution on offset planes, 3-D sort, zero phasing, normal moveout using a velocity field from the underlying conventional seismic data, stack, 3-D post-stack Kirchhoff migration using a velocity field from the under- P-Cable data P-Cable is ultrahigh resolution, low-fold seismic data that are acquired by using innovative field equipment. The main difference from conventional acquisition comes from the use of a cross cable from which the short mini-streamers are hung. The resulting data had a 2-sec record length with 0.5-ms sampling. The shot interval was 12.5 m (41 ft), and the data were recorded on 16 mini-streamers each with eight groups at 3.125-m (10-ft) spacing. The ministreamer separation of 9.5 m (31 ft) was maintained by the Figure 2: Original processing of conventional 3-D data (left), high-resolution reprocessing of conventional 3-D data paravanes keeping (center), and ultrahigh resolution P-Cable (right) are shown.

Structural Modeling Tools for Oil and Gas Recovery New tools are part of an integrated seismic-to-simulation workflow that supports informed decision-making. CONTRIBUTED BY EMERSON PROCESS MANAGEMENT year on from the successful launch of Roxar RMS 2013, Emerson Process Management will be showA casing its new structural modeling tools for exploring fault and horizon uncertainty at this year’s PETEX. The new tools are part of an integrated seismic-tosimulation workflow that helps operators make informed decisions across the prospect life cycle and maximize oil and gas recovery from their assets. Whereas traditionally, reservoir modelers have relied on best-case estimates of faults and horizons with an inherent uncertainty in their interpretations, the tightly integrated structural modeling workflow within Roxar RMS will enable users to quantify uncertainty more effectively and increase decision-making confidence. As part of the new developments, Roxar RMS’s fault uncertainty features have been tightly integrated with structural modeling and 3-D gridding tools to enable users to build fault uncertainty models in full and investigate a wide variety of scenarios related to the uncertainty in the input data. Horizon uncertainty modeling also will be significantly enhanced, allowing users to incorporate realistic uncertainties into the horizon model by specifying uncertainties in the form of standard deviations for all input data used. These include isochore thicknesses, seismic inter- 6 pretations in time with corresponding interval velocities, depth maps, and well data in the form of both well picks and zone log information. The result will be realistic structural scenarios and improved volumetric sensitivity studies. A new version of Roxar RMS will be available soon with improved usability, performance and efficiency features that form part of an integrated modeling workflow. This includes RMS Data Explorer, a new data browser for locating and organizing data objects; the introduction of multithreading (the ability for computing to take place in parallel) to accelerate model building; and a new adjust-to-wells feature that calculates residuals between the grid and well picks and, if required, adjusts the grid to match the well picks.

At Hannon Westwood, the company takes an active interest in exploration both offshore and onshore the U.K. Until recently, onshore U.K. has been overshadowed by E&P in the offshore, particularly the North Sea. This is likely to change, however, as operations in the North Sea become more difficult. Increasing numbers of prospectors are searching for oil in southern England as well as in Yorkshire and the East Midlands. Although recently in decline, the company’s prediction is that there will be a long-term increase in oil prices, and with continued political instability in the Middle East, alternative areas are becoming more attractive. Although most of England is not suitable for exploration, oil has been pumped from beneath Kimmeridge Bay since the 1960s and from the Wytch Farm oil field since 1979. It is believed that there is exploration potential in adjacent areas including the Isle of Wight. Hannon Westwood has been able to provide advice to operators on aspects of the exploration potential on the Isle of Wight as well as 2015 20 & 21 MAY UNDERPINNING THE FUTURE – DISCOVERY, DEVELOPMENT, RECOVERY commentary on data exploration to date and strategies to progress exploration efforts. In addition, the company has produced a report on the potential of the onshore U.K., which alongside Highland Geology’s new report on the seismic interpretation and mapping of the prospectivity of the Isle of Wight and the Novas Consulting report on unconventional potential onshore U.K., provides a comprehensive review of all aspects of the prospectivity and potential for access for the onshore U.K. Chris Bulley, executive director of Hannon Westwood, who will be speaking about the U.K. market on day one at PETEX 2014, considers that, following the announcement of the 14th round, onshore activity has the potential to grow significantly. However, there are many shortterm issues to overcome with a real need for positive education on the benefits and environmental impact of onshore E&P. Bulley’s talk, “The U.K. Market A&D and Activity Levels—Past, Present and Future,” will be dealing with past, present and future activity levels offshore the U.K., where recent declines in exploration drilling activity have been causing concern. Hannon Westwood considers that there is certainly still potential on the U.K. Continental Shelf (UKCS), although there are considerable challenges in unlocking resources in this area. Exploration activity is currently at an all-time low with only 14 exploration wells spudded last year, and many of the prospects are very small. The average prospect size in the Hannon Westwood UKCS inventory is just 10 MMboe, and the age of the current infrastructure makes the development of exploration successes problematic in many cases. Charles Westwood, executive chairman of Hannon Westwood, considers that to make further North Sea exploration viable, there is an urgent need to increase exploration activity. This, in turn, needs to be supported by substantial and targeted tax incentives. It appears that the U.K. government has grasped the urgency of this, and Hannon Westwood hopes that the new regulatory body they have set up will be effective in simplifying and fasttracking applications for seismic and drilling activity. n WELCOME continued from page 1 SP O PA NSO AV CKA RSH AIL GE IP AB S LE! 20 & 21 MAY 2015 ABERDEEN EXHIBITION & CONFERENCE CENTRE CALL FOR ABSTRACTS NOW OPEN!

A particular highlight will be hearing how companies are overcoming the challenges of developing the large offshore heavy oil fields. The PETEX Forum will explore the technical feasibility of shale gas extraction in the U.K. through an interactive panel debate session featuring representatives from both optimistic and pessimistic viewpoints. The debate will be fully interactive, and delegates are encouraged to submit questions to the panel. The forum will be preceded by a special thematic set to provide grounding to delegates in advance of the panel debate. I extend my thanks to Hamish Wilson (SLR Consulting) for once again organizing the PETEX Forum. We are heading into choppy waters in our industry, with oil prices recently sinking to around $80/bbl and costs remaining stubbornly high. The cost challenge is one that all sectors of the industry face, and technology is one area we consistently look toward to help us de-risk prospects and reduce development costs. We shouldn’t underestimate the cutting-edge technology that has been developed by innovators in our industry, working in oil company research centers and in the service sector, where the drive to improve software, equipment, tools, and expertise is unrelenting. This is why PETEX continues to focus on showcasing the latest technologies to help explorers capture uncertainty and find hydrocarbons in the most cost-effective manner. Mike Branston (Schlumberger) and Tim Sears (BP) have assembled an excellent program highlighting the very latest in seismic technology, with real-world examples from across the life cycle including acquisition, processing, modeling, inversion and time-lapse seismic. The 3-D Visualization Theater makes a return to the exhibition floor this year, made possible by the additional space available through our move to ExCeL. The theater also has a dedicated program of 3-D immersive presentations from various vendors who will use technical case study examples to demonstrate their toolkit capabilities. Thanks are extended to Schlumberger and Barco, who have donated their own staff and equipment to bring this attraction to us. We had many excellent submissions following our call for papers earlier this year, and many were an excellent fit to the themes and topics requested. We had so many in fact, that we could not accommodate all of them in the core oral program. This means we have an exceptionally strong poster content this year that has a dedicated presentation program running in parallel with the core program. And finally, for the first time this year PETEX will be making awards for Best Presentation from the core technical program (three categories of International Exploration, Enabling Technology and UKCS) and Best Poster. The awards will be presented by Professor Iain Stewart at the end of the PETEX Forum at 12:15 on Thursday, Nov. 20–we hope you will attend! I do hope you will enjoy everything the show has to offer–and don’t forget that by participating, you are also helping the PESGB to nurture our geoscientists of the future, as a large proportion of the proceeds of the event fund the MSc student bursaries. n P R E V I E W | NOV. 18, 2014 | E&P DAILY NEWS 07/11/2014 09:47:22 Exhibition floor plan and list of exhibitors Company Name Booth number Advanced Logic TechnologyE6 4 Gen Energy UKF5 AAPG DatapagesE7 AAPG EuropeE1 Acceleware A12 Allan Webb A30 ALS Petrophysics A10 Amplified Geochemical Imaging G5 APT (UK)C32 Aramco overseas company UK A29 ARK CLS G9 ARKeX G10 Astrium G6 Bell Geospace C4 BG Group Grad Career Fair Blueback Reservoir F15 Bridgeporth E37 C&C Reservoirs H3 CGG Grad Career Fair CGGB1 Chemostrat A9 DataCo B42 DeloitteC25 Department of Earth Sciences, Royal Holloway UF - J dGB Earth Sciences A4 Directorate General of Oil And Gas Indonesia IP - M Dolphin GeophysicalE20 Down 2 EarthF3 DownUnder GeoSolutions G13 DPTS B15 Durham University B25 EAGE C8 Earthworks Reservoir B10 EliisC3 EMGSG2 EnergisticsH1 Envoi B40 EPI Group A24 ERCL/SAER A52 Company Name Booth number ETAP IP - H Etches CollectionD3 Exploration Electronics A27 Exprodat Consulting A40 FairfieldNodal A50 Faro Technologies UK G1 Faroese Earth and Energy Directorate IP - P ffAD4 Fluid Inclusion Technologies A47 Followave G8 Frogtech Pty F1 FugroC12 Gardline Marine Sciences A46 GEO ExPro (GeoPublishing) C5 GeoGuide Consultants D5 GeokineticsD7 Geological Society of LondonC6 Geologix C13 Geoscience C30 Geotrace Technologies C20 GetechD41 Global Exploration Services C33 Halliburton Energy Services C1 Hart EnergyH2 Heriot-Watt University, Institute of Petroleum Eng.

The system has operated on a number of hydrocarbon assets, and the results are impressive (Figure 1).

The integration of these nonconventional technologies with traditional reflection seismic methods can reduce exploration risk. The objective of the study, titled “A Review of Specialist Geoscience Technologies for the Global Oil & Gas Industry,” is to provide an evidence-based route map of how to apply geoscience technologies—so is a valuable technology selection guide for explorers. With contributions from seven leading experts including, ocean-bottom expert Dr. Ian Jack and crustal seismology studies expert Professor Jannis Makris, the report reviews the suitability and applicability of specialist geosciences technologies in a range of geological settings, the release said. The technologies reviewed in the report are: • Crustal studies (refraction seismic); • Gravity and magnetics; • Full-tensor gradiometry; • Marine electromagnatism (CSEM and MT); • Ocean-bottom nodes; and • Microseismic and induced seismicity. SLR’s technical director, oil and gas, Hamish Wilson, who along with Dr. Matt Luhesi and Dr. Keith Nunn edited the report, said, “There is no ‘holy grail’ detection technique that will prove the presence or absence of hydrocarbons before drilling. However, we believe that these technologies, if used in the right geological conditions and in combination with other techniques, could greatly add value to an exploration review. “An improved ability to remove ambiguity in subsurface systems is a real game-changer with applications from exploration through to development and production, off- and onshore.” The report is available for sale through SLR.

Contributed by the etches collection a not-to-be-missed opportunity at the upcoming PETEX 2014. It’s the chance to meet and share Tthehere’s stories of Steve Etches, the hugely engaging and knowledgeable collector of Kimmeridgian fossils (more than 2,000 incredible examples—many of which are a scientific first). He will be talking about his amazing collection, bringing to life these unique examples, their significance and their place in the Kimmeridgian story. It’s an opportunity that no petroleum geologist should miss. Details about a new museum that has been purpose designed to house this amazing collection also will be discussed. The Etches Collection, as the new museum will be called, will offer year-round viewing of this important collection and will serve as a resource from which Etches can continue his incredible work. Based in the village of Kimmeridge and close to the important Kimmeridgian oil shales, it will be a must for those planning educational field trips or who would like to hold an event, seminar or meeting in a most inspiring and unusual venue. The museum will open in early 2016. Etches will be talking about his collection and the museum on Tuesday, Nov. 18, in the theater space at PETEX. The Etches Collection also will be featured in the PETEX exhibition hall at booth D3, close to the theater. Presentation in the theater The presentation is scheduled to take place at 13:30 and 15:30 on Tuesday, Nov. 18, and will be given by Etches, in company with Professor Simon Conway Morris FRS from the Department of Earth Sciences at Cambridge University and Dr. David Martill from the School of Earth and Environmental Sciences at the University of Portsmouth. Lively talks will explore the extraordinary collection and discuss its value to science and the oil industry.

With 3-D CSEM surveys mapping resistive bodies in the subsurface, the integrated interpretation of EM anomalies into the exploration workflow is providing operators with a clear correlation between the response of the EM measurements and the fluid content of the reservoir as well as acting as a key complement to seismic. CSEM surveys and subsurface resistivity are being used to improve play and prospect evaluation and well positioning, to optimize portfolios, to define appraisal programs and characterize gas hydrates (either as drilling hazards or for commercial exploitation) and for structural imaging in salt and basalt environments. Furthermore, the growing popularity of CSEM has been reflected in a number of recent contracts awarded to EMGS including 3-D EM data acquisition surveys offshore Malaysia and offshore Brazil and the provision of 3-D EM data from EMGS’s multiclient data library for operators involved in exploration in the Barents Sea. In terms of completed surveys, EMGS has been playing a key role in the harsh and sensitive environment of the Barents Sea, influencing lease sale decisions and reducing the occurrence of expensive dry holes and noncommercial discoveries. In an area of complex geology and where seismic data alone can struggle, multiclient EM data has improved the success rate of subscribing operators and has led to a new play type in the Hoop area as evidenced by the Wisting discovery. Furthermore, in the case of the Skrugard and Havis discoveries (now the Johan Castberg Field), two adjacent dry wells could have been avoided with the results correctly predicted by the EM data. On the other side of the Atlantic, EMGS also has played an important role in the Mexican Gulf of Mexico where an extensive 3-D EM program has lowered exploration costs and increased discovery rates for Mexican operator PEMEX. In one case involving PEMEX, CSEM is complementing seismic as part of a 3-D CSEM inversion survey. Here, imaging results have demonstrated that the incorporation of resistivity data into the seismic velocity model building workflow has significantly enhanced the resolution of seismic sub-salt imaging. In such cases, a 5% to 10% improvement in the imaging of the structure post-migration can have a huge impact on future drilling and appraisal decisions and accompanying costs. n 11 We see energy.
