ABSTRACT
This report covers the drilling activity in the Upper Gulf Coast of Texas. Located in the southeastern corner of Texas, the area includes 29 counties, comprising Texas Railroad Commission District No. 3, as well as the adjacent Continental Shelf.
There was a further decline in both drilling and oil production in 1958. The Texas state-wide number of producing days in 1958 averaged 10.16 days per month versus an average of 14.25 producing days per month in 1957. Gas production, however, increased slightly over 1957.
In 1958 32 new oil and gas fields were discovered, most of the discoveries being along the deep Frio, Yegua, and Wilcox (Eocene) formational trends.
Onshore exploration and drilling activity declined during 1958. On the Continental Shelf, 3 more wildcats were drilled in 1958 than in 1957, resulting in the discovery of one new field. It is hoped that both exploration and drilling will show an increase during 1959.
