Magnus® RSS, LWD Services Provided High-Quality Data While Drilling Complex Sidetrack Well in the North Sea

Navigate a challenging directional profile with anti-collision from a busy platform.
Acquire all LWD data including azimuthal dip-picking.

Weatherford experts recommended an integral solution, including the 675 Magnus rotary steerable system (RSS).
The LWD team deployed the PressureWave formation tester and the following sensors: AZD, TNP, MFR, BAP, and total gamma.
The well profile was S-shaped with 3 to 4°/100 ft (30 m) dogleg severity (DLS) requirement for turn and build/drop, with the maximum inclination building to 60°.
Drilling parameters were managed in real time to optimize drilling performance, with 24/7 operational support by the Weatherford Real-Time Operations Centre (RTOC) and monitored in the real-time viewer as part of the CENTRO platform.

Real-time bed dip-picking helped to position the well and make a decision on the trajectory plan. Some potential fractures were also identified, and confirmed by losses, which may have compromised borehole stability and drilling activity.
