Traditional Acid Breakers
Traditional acid breakers can:
▌ Expose corrosive acids, which can
lead to HSE issues
▌ Provide uncontrolled and localized
reaction
▌ Increase the risk for wormholing
▌ Require specialized trucks, tanks and
equipment

Baroid’s Solution – N-FLOW™ Filter Cake Breakers
N-FLOW™ breakers offer a delayed
reaction, providing uniform distribution,
reducing the risk of ‘hot spots’, and
preventing the risk of corrosion and
formation damage.
▌ Oil and water-based filter cakes
▌ For formations with a wide range
of temperatures and pressures

Case Study – N-FLOW™ 325 Filter Cake Breaker System
Leads to Increased Production Rate
Location: Kazakhstan, Mangistau Region
CHALLENGE:
 Reducing formation damage in newly drilled 6” production intervals and in older wells during workover
operations
 Increasing production rates
 Removing filter cake
SOLUTION:
 BARADRIL-N® non-damaging drill-in fluid was used, providing a thin filter cake, and helping to prevent damage
to the reservoir
 After extensive testing, the N-FLOW™ 325 system was customized for the operator’s well conditions and
proposed as the filter cake breaking system
 Laboratory test results were reviewed by Baroid Global Technical Advisors and the program was implemented
on 5 trial wells
RESULT:
 After treatment of the wells with the N-FLOW 325 system, the operator’s production department measured an
increase in the productivity index
 Averaged over the 5 wells, the increased production rate amounts to 86.2% improvement in produced oil
volume

Case Study – Engineered Baroid Fluid Systems Help
Operator Exceed Predicted Production Rate in Tight
Sandstone Reservoir
Location: Central Saudi Arabia
CHALLENGE:
 Minimize formation damage, and ultimately increase reservoir producibility while drilling a 1,660 ft 6 1/8-in
reservoir section horizontally across sandstone formation
 Logging-while-drilling data also showed a major shale body on top of the sandstone reservoir section to be
drilled
SOLUTION:
 The interval was drilled with an 8.7 lb/gal (65 pcf) INVERMUL® oil-based mud
 The open hole section was then enlarged to 7-in and displaced to a customized 8.7 lb/gal (65 pcf) solids-free oilbased drill-in fluid (DIF)
 A 68-bbl N-FLOW™ treatment was placed inside and outside the screen using the rig pump at a rate of 250
gpm. The drillstring was then pulled to the top of the screen. After 1.5 hours, losses averaging 60 bph were
observed. This indicated that the N-FLOW breaker delayed reaction had performed as planned.
RESULT:
 After the well was brought on production, the operator reported oil flowing immediately upon submersible pump
activation at a steady productive rate, significantly exceeding offset producers performance

Case Study – Non-Damaging Water-Based Fluid and N-FLOW ™ 408
Breaker System Lead to Maximum Production Rates
Location: United Kingdom
CHALLENGE:
 Minimize formation damage
 Optimize production through removal of filter cake without inducing losses
SOLUTION:
 BARADRIL-N® water-based drill-in fluid system was bridged with a blend of acid soluble calcium carbonate
material specifically tailored to the porosity range of the reservoir
 N-FLOW™ 408 breaker was designed to remove the bridging material and filter cake
 Both fluids were tested against the reservoir core to ensure compatibility and minimal formation damage
RESULT:
 The reservoir section was drilled successfully, ensuring minimal seepage losses and damage to the formation
 The N-FLOW 408 breaker successfully removed the filter cake from the wellbore, allowing the operator to
successfully test and suspend the well
 After the N-FLOW 408 breaker was spotted and inhibited for 24 hours, the maximum constrained flow rate of 52
million scf per day was reached and was well within the anticipated range.
