DSI Dipole Shear Sonic Imager

Our petrotechnical experts work with you to apply advanced interpretation techniques and workflows to the measurements with combined monopole and dipole acquisition by the DSI dipole shear sonic imager. Advanced sonic waveform processing and analysis provide critical information for completion optimization, sanding prediction, wellbore stability studies, and mechanical earth models. Shear wave splitting and orientation of the fast shear azimuth guide lateral well placement, and Stoneley analysis can indicate and characterize fractures as well as reveal formation mobility.
