Multipole Sonic-While-Drilling Technology Delivers Quality Data Regardless of Mud Slowness

As the pace of exploration and production activity accelerates and the cost of drilling, evaluating, and completing wells continues to rise in complex deepwater and unconventional plays, operators are seeking new logging-while-drilling (LWD) tools that offer real-time measurements comparable to proven wireline logging technologies. Obtaining continuous high-quality data during drilling operations can dramatically improve safety and reduce nonproductive time (NPT) by enhancing an understanding of geomechanical conditions and mitigating uncertainty in borehole stability.

Advanced LWD systems give engineers “eyes down the hole” long before they would normally deploy traditional logging tools. This enables the value of real-time decision making, reduces logging risks, and guarantees data acquisition in challenging wells.

In response to continued advances in LWD technology over the past decade, oil and gas companies are increasingly demanding access to robust real-time and recorded compressional and shear sonic data in both fast and slow formations. In costly deepwater wells, such data can enhance geomechanical models, improve wellbore stability monitoring and pore pressure prediction, and provide sonic-to-seismic tie-in, thereby minimizing drilling hazards and uncertainties in well placement and casing positioning. In high-tier horizontal wells in tight gas and unconventional shale plays, having reliable compressional and shear acoustic data while drilling can improve rock mechanics, fracture detection and characterization, perforation design, and hydraulic fracture optimization.
