The Bloodworth Northeast field was discovered in February 1967. The discovery well was the Tucker Drilling Co., Inc., and Peter Henderson Oil Co. No. 1 Foster S. Price, 0.5 mi south of the Nolan County line in Coke County, Texas, and approximately 15 mi northwest of Robert Lee. The producing reservoir is a Canyon (Upper Pennsylvanian) sandstone having 44 ft of unbroken permeability and 18% porosity. A drill-stem test was run in the upper 14 ft of the sandstone section. Gas surfaced in 5 minutes and oil, flowing strongly, surfaced in 30 minutes. In December 1968 there were 28 producing wells and 6 dry holes; 9 of these are multiple completions.

This oil field was discovered as a result of drilling along a productive trend; isopach maps provided the principal lead to the discovery.

The writer had observed that all sandstones within a 350-ft-thick zone contain hydrocarbons regardless of structural position or any other geologic characteristic. Accordingly, cumulative sandstone isopach maps were prepared from spontaneous potential curves. The isopach map on which the discovery well was drilled indicated that 50 ft of sandstone would be present.

The writer believes that the sandstone was deposited originally by turbidity currents in compaction troughs adjacent to the Pennsylvanian reef mounds of the area.

The Texas Railroad Commission recognizes three separate sandstone zones in this field.
