ABSTRACT:
Acoustical logging apparatus is utilized to determine the need for consolidation treatment of an oil-bearing sand formation prior to production and preferably prior to the removal of the drill rig. The relative energy levels and/or the relative velocities of the compressional and shear waves are measured and the ratio of the compressional energy to shear energy and/or the ratio of compressional velocity to shear velocity is utilized to provide an indication of the need for sand consolidation treatment.
