Title: Sonic - gamma ray logs improve bit selection
Abstract: Analysis of logs from neighboring wells has increased the accuracy of matching the proper bit with formations in the Rocky Mountains. Sonic logs record porosity - an indirect measure of rock strength - and gamma logs can be interpreted to reveal shale content. Once these two key factors are known, choosing the most appropriate bit becomes more accurate. 7 refs.
