Abstract
Onshore drilling activity in the Upper Gulf Coast of Texas increased by 13% in 1974. A total of 943 wells was drilled in 1974 compared to 832 in 1973. Exploration success was slightly higher in 1974, with 33% of all wildcats being productive, compared with 29% the previous year. Most of the significant discoveries were drilled in Woodbine Sand of the Cretaceous-Jurassic trend. Seismic activity onshore decreased 40% but increased by 45% offshore. Offshore wildcat drilling increased sharply, especially in the Pleistocene. Most of the significant discoveries were in the Pleistocene gas sands of the High Island South and East areas. The first Federal Lease Sale of the year was held on May 29 and oil companies exposed slightly over $1.5 billion for 565,000 acres in this report area.
