Sperry Drilling, a Halliburton business line, announced the release of Quasar Pulse Service, the only M/LWD service capable of operating in harsh environments up to 392°F and 25 000 psi.
Pushing the limits of current M/LWD services, Quasar Pulse Service can deliver accurate and reliable directional, gamma ray, PWD and vibration data for precise wellbore placement in high temperature and pressure zones. The service allows access to reserves that conventional tools cannot reach and can eliminate the need for mud chillers and ‘staging’ to cool down tools, saving valuable rig time and improving efficiency.
“Operating in harsh environments requires collecting reliable data to reduce drilling risks and optimise production. Quasar Pulse Service is the first M/LWD commercial service to include sensors that have the highest temperature and pressure ratings currently on the market,” said Ahmed Kenawi, vice president of Sperry Drilling.
Quasar Pulse Service includes 4¾ and 6¾ in. size tools, allowing it to perform in wellbores up to 97/8 in. in diameter. With more than 50 successful runs and nearly 90 000 ft drilled, the Quasar Pulse Service has delivered accurate measurements around the world and has been tested extensively in challenging environments in the Middle East, Asia Pacific and unconventional fields in North America.
Recently in the United States, an operator with plans to drill a long horizontal interval in the Haynesville shale, an area well-known for high reservoir temperatures, was challenged to find an MWD system capable of withstanding the heat. Even with the use of mud chillers, standard tools would not have reached total depth, so the operator deployed Quasar Pulse Service.
With temperatures reaching as high as 363°F, the well was completed successfully with a total depth of 22 595 ft and a total vertical section of 10 072 ft, both field records. The operator saved an estimated US$ 209 000 by not staging tools into the well and avoiding a potential trip for failure. Additionally, the reservoir interval was nearly twice as long as typical wells in the area, providing far higher production and potentially reducing the number of wells needed to develop the field.
