Historically, tophole surveys were taken before or after connections, using 100% of connection time for surveying. Noise often required repeats, increasing rig time and costs. As a result, the operator sought a solution to acquire surveys during connections with zero repeats to save rig time and improve drilling efficiency.
Aligned with the operator’s efficiency goals, SLB proposed deploying DGC technology in the tophole sections to boost surveying efficiency and reduce the risk of repeat surveys at the same depth. Implementing DGC technology achieved a total rig-time saving of 127 minutes in the tophole sections, representing a 61% reduction in surveying time compared with traditional GyroLink service surveys conducted either before or after connections. This collaborative approach highlighted our differentiated technology relative to competing gyro-while-drilling platforms.
