RI 3712 Analysis of Oil Production in the Near-Depleted Mexia-Powell Fault-Line Fields of Texas

"INTRODUCTION During the early 1920's world-wide attention was attracted to a group of oil fields (Mexia, Wortham, Currie, Richard, and Powell) later known as Mexia-Powell fault-line fields in Limestone, Freestonne, and Navarro Counties, Tex. Enormous yields of high-gravity oil from the wells in these fields resulted in drilling campaigns that quickly surpassed all previous records for rapid, intensive development of productive areas. The discovery of oil in the Mexia filed in September 1921 was followed quickly by the finding of oil in the Currie field in October. In January 1923 oil was discovered in the Powell field; in February 1924 the Richland field, midway between Currie and Powell fields, was brought in; and in November 1924 oil was discovered in the Wortham field, situated between Mexia and Currie fields. Each of the fileds was developed rapidly: wells were spaced closely and had high initial production; production peaks were reached early in the producing lives of the fields; subsequent decline was rapid, and there was early and rapid encroachment of edge water.In 1927 Bureau of Mines engineers, in their investigations a engineering conditions in oil,completed a preliminary study and published a mimeographed report 4/ on underground conditions in the Wortham field, and in 1928 they reported on production and development problems in the Powell Field. 5/ field."
