Abstract

The Louisiana Gulf Coast consists of the 38 southern parishes and the 16 continental shelf areas offshore. Production is obtained from sediments ranging in age from Cretaceous to Pleistocene. The 2174 exploratory and development wells are 3.9% less than were drilled in 1960. Of the 691 exploratory wells, only 28.4% were successful. Of the 31 new-field discoveries (19 onshore, 12 offshore) the most important are: Gonzales, Ascension Parish; Willow Cove, St. Martin Parish; Block 209 field, Ship Shoal area; Block 129 field, Block 115 field, and Block 16 field, Vermilion area; and the Block 174 field, West Cameron area. The most important of the 395 new pools and extensions include Lake Barre-Lake Raccourci fields, Terrebonne Parish, and Lake Sand field, Iberia Parish. Leasing continued to be very active but scattered, with no unusually large blocks being assembled. Geophysical activity declined except in the offshore, which is principally a geophysical province. In general, 1961 was considered a poor year for the area, and more normal conditions are expected in the coming year.
