Estimation of Skin Effect From Multiple Depth of Investigation Well Logs

摘要

A method includes obtaining measurements of a formation parameter prior to and after treatment of at least one formation penetrated a wellbore formed in the subsurface formation. The measurement correspond to a plurality of lateral depths of investigation. A difference is determined at each depth of investigation between the measurements made prior to and after the treatment. A skin effect is determined for each depth of investigation.
