Powered rotary steerable system boosts deepwater well ROP 157%
Minimize effect of stick/slip on ROP and BHA wear while drilling 9½-in hole sections of deepwater wells in very abrasive formations offshore Angola.
Minimize stick/slip
The 9½-in hole sections of deepwater wells in a field offshore Angola were being drilled through very abrasive formations. This resulted in severe stick/slip that damaged BHA components, quickly wore out stabilizers, and adversely affected drilling performance. To avoid the damage, abnormal wear, and low ROP, the operator wanted to minimize stick/slip.
The PowerDrive vorteX RSS delivered power and torque close to the bit to improve drilling performance.
Japan Oil, Gas and Metals National Corporation (JOGMEC), formerly Japan National Oil Corporation (JNOC), and SLB collaborated on a research project to develop LWD technology that reduces the need for traditional chemical sources. Designed around the pulsed neutron generator (PNG), EcoScope service uses technology that resulted from this collaboration. The PNG and the comprehensive suite of measurements in a single collar are key components of the EcoScope service that deliver innovative LWD technology.
