Halliburton Introduces Point-The-Bit Rotary Steerable System
The Geo-Pilot EDL 9600 rotary steerable system (RSS) is the only RSS for big holes that can deliver well profiles previously only possible with motors, but with the wellbore quality and higher rates of penetration of a point-the-bit rotary steerable system.
Sperry Drilling’s Geo-Pilot EDL RSS features an enhanced dogleg capability; the system can be used where high build rates are required or where soft formation typically limits build-rate capability. The Geo-Pilot EDL system can also deliver a more consistent build rate through interbedded formations.
The Geo-Pilot EDL system matches the appropriate bit to the rotary steerable system to deliver optimized drilling performance. The system is ideal for drilling well trajectories for extended-reach drilling applications, where consistent doglegs are required to drill the surface hole in shallow, soft formations.
These well trajectories improve drilling efficiency by reducing the sail angle required, reducing torque and drag, and facilitating faster, smoother tripping. With a high-build-rate RSS, the well can be kicked off deeper and land in the reservoir sooner, thus increasing reservoir exposure. The system also allows drilling of the vertical, curve and lateral sections in one bottomhole assembly (BHA) with no added trips for motors.
Halliburton’s Geo-Pilot EDL system has been used in offshore and onshore operations to drill hole sizes ranging from 8-3/8-inches to 17-1/2-inches, delivering consistent higher doglegs previously only achieved using downhole motors. In the first extensive application of the Geo-Pilot EDL 9600 series system globally, Sperry Drilling drilled six complete build sections from vertical to horizontal, delivering excellent performance, including consistent dogleg capability up to eight degrees per 30.5 metres/100 feet with reserved deflection capacity to reach 10 degrees per 30.5 metres/100 feet.
Halliburton serves the upstream oil and gas industry throughout the life cycle of the reservoir – from locating hydrocarbons and managing geological data, to drilling and formation evaluation, well construction and completion, and optimizing production through the life of the field.
