Interbedded and fractured carbonates posed a significant challenge for drilling the horizontal section of wells in the East Java Basin. To successfully drill the horizontal, the operator needed to overcome the constant microdoglegs observed in offset wells that resulted in unstable DLS, severe shock and vibration, and stick/slip conditions, compromising directional control and ROP.
Conventional RSS tools had difficulties precisely and consistently landing offset wells inside the reservoir with sufficient DLS.
In concert with the MicroScope HD resistivity- and high-definition imaging-while drilling service to better navigate the well trajectory, the PowerDrive Orbit G2 RSS was used to deliver higher DLS and wear resistance in harsh downhole conditions for longer runs with greater trajectory control.
As compared with conventional RSSs used in offset wells, the PowerDrive Orbit G2 RSS increased the maximum DLS by 50% and the average DLS by 80% while maintaining a constant steering ratio and reducing wellbore tortuosity and microdoglegs.
The PowerDrive Orbit G2 rotary steerable system drilled the horizontal section of a complex well in one run, delivering greater directional control and higher dogleg severity (DLS) as compared with conventional tools.
