Case Studies
WelSAVER™ Controls Severe Losses and Enables Successful Drilling Through Olmos Formation in Eagle Ford Basin
While drilling the intermediate section of a well in Frio County, Texas, the operator encountered unexpected formation behavior that resulted in significant drilling fluid losses. Loss rates ranged from approximately 55 barrels per hour to complete loss of returns, creating a high risk of nonproductive time and operational delays.
WelPAN™ Reinforced Cement System Improves Annular Bond Integrity in Oklahoma Remedial Cementing Operation
A remedial cementing operation was conducted on a well located west of Orienta in Major County, Oklahoma with the objective of restoring annular cement integrity and verifying the effectiveness of the cement placement.
SuprSeal® Stops Severe Losses and Restores Circulation During Lateral Drilling
While drilling a 6-1/8 in. lateral section in Lincoln County, Oklahoma, the operator encountered an unexpectedly weak formation that resulted in severe fluid losses and loss of circulation. Multiple attempts were made to regain returns using conventional lost circulation materials. Three pills consisting of Magna Fiber and calcium carbonate (8 lb/bbl each) were pumped, but the loss zone continued to take fluid and circulation could not be restored.
Kol-Seal® Lightweight Cement System Enables Effective Placement and Long-Term Zonal Isolation in West Texas Wells
A major West Texas service company was cementing a series of wells characterized by low fracture gradients and relatively low temperature conditions. These formations presented a narrow pressure window where excessive hydrostatic pressure from conventional cement slurries could damage the formation and compromise cement placement.
Kol-Seal® Lightweight Cement System Enables Reliable Liner Cementing and Zonal Isolation in UAE Well
A major operator in the United Arab Emirates required a cementing solution capable of achieving uniform cement coverage across a highly compressible sand interval within the annulus. If the sand were allowed to subside, the resulting formation compaction could lead to production liner buckling and potential well integrity risks.
Kol-Seal® Carbon-Based Cement Additive Improves High-Temperature Slurry Performance in Oklahoma Well
A major service company operating in Oklahoma required a specialized cement slurry design capable of performing under elevated downhole temperatures while maintaining reliable placement characteristics.
