Engineered drilling solution delivers more precise directional control, maximizes asset valueDownload PDF
Drill a long lateral using a MWD/LWD service
An operator in Thailand needed to drill a 6⅛-in. long tangent section with a steep inclination of ±60°. They planned on using a 5-in. TerraForce™ positive displacement motor and Quasar Trio® measurement-while-drilling/logging-while-drilling (MWD/LWD) triple-combo service to provide an IADC rate of penetration (ROP) of 30 fph, while maintaining precise directional control.
Halliburton Sperry Drilling proposed a customized, multi-component BHA design, in conjunction with an Agitator™ tool to improve weight transfer to the bit. The section was successfully drilled to total depth (TD), which resulted in an interval length of 6,194 ft (1,888 m) MD with an inclination of 59°. The average on bottom ROP was 55.45 fph – IADC ROP of 40 fph. The optimized Agitator placement led to minimal vibration and no interference with MWD telemetry.
The Sperry Drilling engineered solution and performance met customer expectations to maximize asset value and, on the strength of the performance, the operator decided to grant Sperry Drilling a total of six extra wells.

Designed for extreme high-temperature and high-pressure environments.
Telemetry services transmit downhole data from MWD/LWD tools to the surface to provide operators real-time drilling and reservoir insights.
Directional drilling systems engineered to reduce well time and maximize reservoir contact from unconventional land to extended-reach deepwater drilling.
