Keeping with the Oklahoma Geological Survey's mission to investigate the geology of the State and to disseminate results of such investigations to the public, this compact disc identifies wells in Oklahoma that have penetrated the entire sedimentary rock section to reach basement (igneous and/or metamorphic) rock, and at what depth. Some of the wells are noted as having drilled through a thickness of basement, and back into sedimentary rock. These wells define reverse faults.

A database of 1,232 wells drilled to basement in Oklahoma was compiled using well information derived from 17 published and unpublished sources, 14 individual contributors, and personal examination of some electric logs by Jock A. Campbell.

Previous lists and studies of basement rocks focused on a particular region of Oklahoma. To the best knowledge of the authors, this is the first list covering the entire State and made available to the public. The authors make no claim that this compilation is complete.
