Terms of this contract as they involve this particular study, are restated here so that reviewers may be aware of the basic aims of the project. Project I - Evaluate the Petroleum Potential of the Proposed Radioactive Waste Disposal Site: Initial studies to be completed by February 15, 1973, will involve the development of pertinent information related to the locationof a favorable site for coring of the Salado Formation and underlying rocks somewhere within Ts. 22-23 S., Es. 21-22 , Rs. 31-32 E. Evaluation of petroleum potential of the above-mentioned townships will include all rocks from the surface to the Pre- Cambrian Erecambriaa basement with emphasis on the deeper horizons. This study will include all wells in the area, and pertinent structural, lithologic and isopach data for the proposed disposal site. Necessary regional interpretation of these strata will be conducted and will include existing fields, wells, secondary recovery operations, areas of salt water disposal, production data, and pressures.
