Title: No. 1 Play in U.S.A.--South Louisiana Tuscaloosa Trend, 1975-80: ABSTRACT

Author(s): Joe B. Adams, Frank W. Harrison, Jr.

Article Type: Meeting abstract


Since the May 31, 1975, discovery of Tuscaloosa production at False River field in West Baton Rouge Parish, Louisiana, the Tuscaloosa trend of south-central Louisiana has developed into the most active deep exploratory play in the United States. Drilling activity since the discovery of the False River field has resulted in the additional discovery of 13 Tuscaloosa gas-condensate fields, one Tuscaloosa oil field, three Austin Chalk discoveries, and one Wilcox discovery. As of March 1980, 241 permits have been issued by the Louisiana Department of Conservation. Of this number, 119 are wildcats which have been drilled or are drilling below a depth of 15,000 ft (4,572 m). The success ratio for wildcats is one of six, or 16 2/3%, and field extension and development drilling ha resulted in a success ratio of one of two, or 50%.

There are more than 4 million acres (1,600,000 ha.) under lease in the trend; 129,680 acres (51,872 ha.) have been placed in Tuscaloosa drilling units by the Louisiana Department of Conservation. Some of the most significant fields discovered along the trend are the False River field, West Baton Rouge Parish; Moncrief, Judge Digby, and Moore-Sams fields in Pointe Coupee Parish; Port Hudson, Irene, and Profit Island fields in East Baton Rouge Parish; and Lockhart Crossing field in Livingston Parish, Louisiana. Proved reserves of 4 Tcf of gas and 400 MM bbl of condensate have been established. In addition, available seismic and subsurface data indicate the future reserve potential of the Tuscaloosa to be estimated at 16 Tcf of gas.

A detailed subsurface and stratigraphic study of the existing fields to date should serve as a guide for locating other major reserves along the trend.
