This report includes X-ray CT imaging of whole or slabbed core from four wells drilled in southwest Arkansas: Weiser-Brown Rainbow #1 in Miller County, Anadarko Talley #1-22, DOW Chemical Smith #1, and Tenneco Nations K L #1 in Columbia County. Continuous bulk density (RHOB) and photoelectric factor (PEF) curves are computed from the X-ray CT scanning. The purpose of these analyses is to determine the reservoir quality and mineralogy of the lower part of the Upper Jurassic (Oxfordian) Smackover Formation as an unconventional oil mudstone resource play in southern Arkansas and northern Louisiana.
