information you can use to reduce risk and increase
your chances of success.
07
Integrate data and extend workflows
for comprehensive, reliable earth modeling
Integrating the Omega and Petrel platforms introduces a
new way to bridge the gap between two historically separate
worlds—the highly visual and interactive world of interpretation
and earth model building and the computationally intensive
world of migration and tomographic inversion. This integration
enables you to build more accurate, comprehensive earth
models than ever before to solve complex imaging problems
with greater efficiency.
Enhance team performance with scalability
The Earth Model Building collection is a full suite of interactive
plugins that allows you to build velocity models and execute
depth-imaging workflows though the integration of the Petrel
and Omega platforms. The suite meets the need for efficient
integration of interpretation, modeling, and seismic processing
tools to facilitate any imaging workflow.
Because the computing requirements of advanced algorithms
are increasing, the Omega platform provides a scalable highperformance computing solution to effectively utilize any size
of cluster (CPU or GPU) to minimize the time it takes you to arrive
at a solution. The software developer’s kit (SDK) enables your
developers to introduce your company’s intellectual property
into the environment.
The Omega platform incorporates a proprietary massively parallel
infrastructure that is fault tolerant and allows you, to dynamically
change allocated resources to jobs as they are executed. In
combination with the job scheduling system, this allows you
to maximize the resource use of your data center.
08
Project model
Project management
The Omega platform uses an Oracle® database to store all
project information. The Omega platform project model (OPM)
controls interactions between Oracle and all other Omega
platform applications, making data access very efficient. In this
database-driven environment, where all applications are linked,
a complete history of the processing project is recorded and is
always accessible.
The Omega project manager application allows the geophysicist
to define the project hierarchy—i.e., the organizational structure
of the seismic processing project. Seismic surveys can be
divided into different processing steps (e.g., demultiples, velocity
analysis) or different vantages in 4D acquisition. A processing
workflow can be easily laid out so that the organizational
structure of the work to be performed is clear to all participants.
This processing hierarchy, or sequence, is displayed in the project
manager application, where individual jobs are displayed along
with any ancillary data.
OPM allows multiple geophysicists—in a true multiuser
environment—to work productively on the same survey.
Additional management tools include the stage jobs viewer,
job monitor, and multijob monitor. These allow for the easy
monitoring of processing workflows at various levels of detail.
The prior usage of any dataset can be quickly tracked using
the dataset history tool, which allows a geophysicist to rapidly
understand the workflows, algorithm parameters, and velocities
that have been used to process a seismic dataset.
09
Automation
The Omega platform is highly automated at both the
infrastructure and desktop levels. Routine tasks such as data
management, job submission, and QC are easily automated,
allowing the geophysicist to concentrate on geophysics. Nearly
all data management tasks, such as selecting seismic files,
outputting data to disk, load-balancing disks, and archiving and
retrieving data from tape, can be automatically handled.
Additional automation tools increase geophysicist productivity
when managing a project. Tools such as job analysis (to check
job run statistics), triggering (automated job submission based
on given criteria), and QC sessions in SeisView software increase
throughput during production processing, allowing for detailed
QC on even the largest projects.
A robust batch production processing system for bulk processing
includes all the tools necessary to schedule and manage large job
queues. A geophysicist can quickly and easily submit hundreds
or thousands of separate jobs to the batch queue.
The batch production processing system allows for parallelization
in two forms: explicitly parallelized algorithms (mainly migration
algorithms), and the ability to subdivide a survey and dispatch
the data to multiple computational nodes within a cluster. This
same system is in daily use at at Schlumberger processing
centers worldwide to process huge volumes of seismic data
efficiently and accurately.
Workflow building
The Omega platform allows for the intuitive creation of
processing workflows with its graphical workflow builder,
SeisFlow. Processing workflows are created interactively by
selecting and inserting one of 400+ algorithms into the SeisFlow
canvas. Each algorithm within the platform is graphically
parameterized and contains detailed help documentation for
each parameter setting, as well as details of the geophysics
behind each algorithm. SeisFlow allows for the construction of
a wide range of processing workflows, from simple data input or
scaling to extremely complex 3D demultiples or depth migrations.
10
Omega platform processing workflows can be submitted to a
Linux computational node in three ways:
■■
batch, submitted to a Linux cluster
■■
immediate, submitted to a targeted node
■■
interactive, submitted to a targeted node but with the results
displayed in SeisView software on the user’s workstation
without creating an output dataset.
Batch submission is commonly used for production processing
or parameter testing on complex processing workflows, whereas
immediate or interactive submissions are used mostly for
parameter testing because of their quick turnaround time.
Analyzing seismic data
The Omega platform has multiple applications to analyze seismic
data, including SeisView software—a 2D seismic canvas—and
multiple attribute display (MAD)—an attribute canvas. The
SeisView software offers a robust 2D canvas for viewing full
32-bit seismic data and true random access, along with graphing
and access to trace headers. Data analysis and investigation
can be done using a series of interactive SeisView software
toolkits (based on Omega platform algorithms), including spectral
analysis, autocorrelation, band-pass filtering, F-K and Tau-P
filtering, noise attenuation, muting, and attribute generation.
SeisView software can rapidly compare datasets using roll
and flip displays, on-the-fly difference plots, linkages between
datasets (prestack-to-prestack, prestack-to-stack, and stack-tostack), and corendering of displays.
MAD is the Omega platform QA/QC analysis tool that allows a
geophysicist to either interactively view a dataset’s attributes,
or view, in real time, attributes generated from multiples
production processing workflows on the batch production
system. MAD can be easily linked to SeisView software to
create an attribute analysis workflow, in which attributes
are selected in MAD and seismic data are visualized in
SeisView software.

challenges and make the right decisions.

Operational and licensing models
The Omega platform is available for use in a variety of operational and licensing models.
The platform can support traditional licensing models that include purchase, lease,
rental, and pay-per-use. Operationally, the Omega platform scales seamlessly from
single workstations or blades to major high-performance computing environments.
Schlumberger has recently expanded the operational and licensing modes to include
cloud-based or managed service solutions. The managed cloud models can be
implemented as private or hybrid clouds hosted by Schlumberger in one of our
many data centers, or deployed in your data center or a third party hosting facility.
This allows users to work in a more flexible manner where overflow type capabilities
to existing license numbers can be made available.
