Case History – Clay-Free INNOVERT® High-Performance Invert Emulsion
system introduced into Norwegian market, offering an environmental HP/HT
drilling fluid solution
Location: North Sea
CHALLENGE:
 Expanded environmental regulations in Norway have increased demand for drilling
fluid systems that can meet drilling challenges while remaining environmentally
acceptable.
 A vertical exploratory well similar to the main offset well offered a high degree of
comparison to measure the fluid’s effectiveness
SOLUTION:
 Baroid’s clay-free INNOVERT® system was formulated with XP-07™ base oil to
provide improved ECD control in narrow margins and superior hole cleaning
compared to conventional oil-based systems
 BDF-568™ additive was used in place of RHEMOD L™ suspension agent to
produce the same rheological properties and unique gel structure while meeting
environmental standards
RESULT:
 While drilling with INNOVERT® system, the Operator experienced low and
consistent Equivalent Circulating Density (ECD) in both the 16” and 12 ¼” sections
 ECD was reported throughout at 0.02sg-0.04sg above mud weight in both sections,
an improvement from the 0.02sg-0.1sg reported in the main offset well using a
conventional organophilic clay-based system
 INNOVERT® system reduced fluid losses by 23% compared to previous wells,
representing cost savings of $104,477 USD (598,246 NOK)
 No alternative fluids were needed for the 8 ½” section, resulting in further savings of
$372,717 USD (2,732,462 NOK)

Case History – Baroid Delivers Repeated High-Temperature
Success in the Gulf of Thailand
Location: Gulf of Thailand
CHALLENGE:
 Directional slim-hole drilling, fast rates of penetration, steep thermal gradients, acid
gases and limited solids control efficiency all combined to stress non-aqueous drilling
fluid (NAF) left in the wellbore, working against effective triple combo runs and later
logs.
 Our High-Temperature (HT) fluid solution for these projects requires a thin efficient
filter cake and an advanced stable emulsion which could walk the fine line between
barite sag and excessive gelation.
SOLUTION:
 PERFORMUL HT™ emulsifier replaced other products which could not tolerate
swings in alkalinity. This non-ionic surfactant was teamed up with EZ MUL® NT
emulsifier to produce an invert fluid with minimal gelation over several days at
extreme heat. A careful balance was made with the viscosifier additives to build lowshear rheological properties and reduce the risk of barite sag.
 DURATONE® HT filtration control agent, formed part of the filtration control package
with BDF™-513 copolymer making up the rest to achieve filtrate values as low as 8.0
cc at 425°F.
RESULT:
 Over the past three months we successfully drilled and logged five wells over 400°F
using this fluid solution
 The trials provided evidence of our engineered fluid design and allowed for some key
lessons learned in implementing it.

Case History – Innovative use of N-SOLATE® Packer Fluid
in Gulf of Mexico
Location: Gulf of Mexico
CHALLENGE:
 Lost circulation
 High ECD
 Because of extremely cold sea floor temperatures, the synthetic-based fluid
was becoming excessively thick when cooling off in the riser, requiring
greater pump pressure to move
SOLUTION:
 N-SOLATE 600 packer fluid was used in the riser wall annulus to keep the
heat from the synthetic-based mud (SBM) in the main annulus from being
lost to cold sea floor temperatures
RESULT:
 Once the N-SOLATE 600 packer fluid was in place, further lost circulation
was not experienced
 Equivalent circulating density (ECD) was drastically reduced
 Higher circulation rate and faster drilling rates achieved
 Drilling fluid returned to surface 20 degrees warmer compared to wells
without the insulating effects of N-SOLATE fluid
 Less stress on the wellbore throughout the entire operation
 Major reduction in drilling time and reduction of fluid costs

Case History – Drilling Fluids Graphics (DFG™) Software allows
Operator to save rig time and successfully drill challenging HP/HT well in
Western Canada
Location: Western Canada
CHALLENGE:
 Reduce rig time while drilling and running the casing/liner in a highpressure/high-temperature formation
 Bottomhole Static Temperature (BHST) was up to 170°C
 Narrow pore pressure and fracture gradient window
 Previous vertical well in the area experienced high fluid losses while running
and circulating the production casing
SOLUTION:
 Drilling Fluids Graphics (DFG™) with DrillAhead® Hydraulics Modeling
Software was utilized during planning and execution of the well
 Baroid personnel accurately modeled multiple characteristics for four
different sections of the well
RESULT:
 Modeling of surge pressures prior to running the 7 5/8” casing gave Operator
confidence to increase running speed from 5 m/min to 10 m/min inside the
intermediate casing
 Total casing running time was reduced by 6 hours, with an estimated cost
savings of $18,500.
