QC advances increase confidence in LWD sonic measurements ///

The recent increase in drilling in challenging environments around the world has meant that the effective control and minimization of wellbore stability and pore-pressure related events, and their associated non-productive time (NPT), is critical to success. In addition, potential safety concerns associated with an unstable wellbore are well-known. Acoustics measurements are key, both to reliable pore-pressure prediction and to wellbore stability management.
