Columbia County, Arkansas: Sonic Logs and Velocity Surveys

Petrophysics, Inc. has 7 digitized sonic logs (LAS files) and 7 check-shot velocity surveys for wells in Columbia County, Arkansas (in south Arkansas, around Magnolia). The wells are in Townships 15S–20S and 17N, Ranges 18W–23W. The deepest reaches 12,625 ft. Sonic (DT) is digitized on 7 wells, spontaneous potential (SP) on 3 wells, gamma ray (GR) on 3 wells and deep resistivity (RD) on 3 wells. Operators: ARKANSAS FUEL; ATLANTIC; BRADOOCN, DORAN, ALICE-SIDNEY OIL; CARTER; COBRA O&G; FORTUNE GAS & OIL; MARLIN EXPL.; PAN AM; PETRO-CHEM OPERATING; PRUET OIL CO.; S. O. L.; SHELL MID-CONT; SHENANDOAH OIL.

For geophysics and seismic interpretation in Columbia County, sonic logs and check-shot velocity surveys are the well data that tie wells to seismic: building synthetic seismograms, converting seismic time to depth, and calibrating velocity models.

The county lies on the Smackover trend (Upper Jurassic Smackover Formation play). Formation tops are not recorded in our indexes, so check the logged interval or total depth of each well against the Smackover depth in your area.
