In 1960, 3,538 wildcat and development wells were drilled in the 15-county area comprising North Texas. One hundred fourteen exploratory tests were successfully completed; these included the discovery of 62 new fields, 50 new pools, and 2 extension wells. Most of the new production is from the Pennsylvanian Strawn and Atoka series. Drilling and production maintained a steady pace despite the sharp drop in the number of producing days. The most significant discovery was in the Conley field in the Hardeman basin where 3 new pays were indicated.
