Schlumberger Limited (SLB) said it introduced groundbreaking technologies in Guyana, setting a new standard for performance in offshore operations for ExxonMobil, in the Stabroek Block.
In an open-water-work campaign consisting of 13 wells, SLB said advanced tools revolutionized the drilling process.
“These technologies improved the rate of penetration by an impressive 60%, reduced gyro survey time by 85%, and enhanced steering accuracy by 20%,” the company detailed in its Q1 results report.
SLB said that notable advancements included the debut of a 26-inch polycrystalline diamond cutter bit, the application of the GyroLink™ definitive gyro-while-drilling service, and the integration of a nine-inch DynaForce™ high-performance drilling motor with the DynaPower XE™ extreme-environment motor elastomer in the PowerDrive vorteX™ powered rotary steerable system.
“Additionally, the first use of an AccuStrike™ short-makeup drill bit in Guyana expanded performance capabilities in complex trajectory wells,” SLB noted.
The company said its SureRock™ enhanced sidewall coring solution played a pivotal role in avoiding the need for a bypass well for whole core in the Stabroek Block.
“Leveraging advanced digital capabilities and real-time insights, SLB enabled ExxonMobil Guyana Limited (EMGL) to acquire 118 sidewall cores in just two runs, achieving an impressive recovery rate of 96%. By eliminating the need for a bypass well, EMGL saved 15 days of rig time, which equates to reducing CO2 emissions by 2,550 metric tons, while successfully meeting all formation evaluation objectives,” SLB reported.
SLB asserts its position as the foremost technology provider in reservoir characterization, drilling, production, and processing for the global oil and gas sector. As a prominent service provider, SLB extends substantial technical support to Exxon, particularly in the Stabroek Block, facilitating the proving of hydrocarbon reserves.
In 2017, Schlumberger made a substantial investment, establishing a lasting presence in Guyana with the inauguration of its US$75 million oil services facility base in Houston.
