It became apparent following held appraisal that complex 3D well trajectories would be necessary to exploit the Janice field effectively. Specific challenges included high torque and drag profiles, slow rate of penetration (ROP), tight target tolerances, and effective reservoir navigation. The full-length paper details how a combination of rotary closed-loop steerable (RCLS) and conventional drilling technology was used to achieve field-development objectives. This project provided a unique opportunity to make a direct comparison between RCLS and conventional steerable technology on similar complex 3D web trajectories.
