| dc.description.abstract | Mathematical model calculations and field resistivity measurements related to ground-water investigations on the Llano Estacado were made. The original potential function equations by Ehrenburg and Watson were extended to eleven parallel layers (ten layers and a half space) to represent a horizontally stratified earth. From these equations a computer program was written to calculate apparent resistivities for the Wenner configuration. The properties of this computer program and related plot subroutines are described. Electrical resistivities on the Llano Estacado were determined from available electric logs and surface resistivity measurements in outcrop areas. These regional resistivities were used to represent various earth models for the calculation of apparent resistivity curves by digital computer. A surface resistivity survey covering 150 square miles was carried out in the Yellow House Canyon area. The interpretation was made from an isoresistivity map, resistivity profiles and sounding data. A theoretical formation resistivity analysis, electrical interval logs from surface data and sounding curves computed from an electric log were also included in the area study. A brief review of the history, applied surveys in the Western hemisphere and theory of the surface resistivity method are also presented. A catalogue of 462 apparent resistivity curves is included in the appendix. | |
