Improving rotary steerables using real-time caliper imaging

Poor hole quality causes a tight borehole, packing off, high torque/drag, stick-slip, degraded logging-while-drilling (LWD) and wireline log quality, unpredictable directional performance, and consequently problematic casing runs. Advancements in LWD imaging technology can now allow engineers to identify 3D borehole oscillation issues and oscillation frequencies while drilling. Pathfinder's Junichi Sugiura and Steve Jones discuss.
