Exhibit 7-4
Uncorrected temperatures of formations at 10,000 and 12,000 feet depth from oil and gas well logs
Exhibit 7-4 shows two illustrations of the state of Texas with county divisions. The first map shows the temperatures at 10,000 feet, where the lowest temperatures are in the panhandle, and the hotter area goes from the Valley and eastern portions of the state, with mid range temps in the western and central protions of the state. The other map shows temperatures at 12,000 feet, which depictes much hotter areas speckled along the central portions of the Valley, and not as cold areas in the panhandle, and the northern central portion of the state and the lower center of the west wing of the state had higher midrange temps than the other map. The table in exhibit 7-5 shows more information in a table format.
