Title: Developments in Arkansas, North Louisiana, and East Texas in 1971

Author(s): Ernest H. Morrow (2), Gene C. Sigler (3), James B. Ewbank (4)


Drilling activity increased significantly throughout the CSD Districts covered by this report. Total number of wells drilled in Arkansas increased 9.1%, in North Louisiana 33.5%, and in East Texas 6.0%. Exploratory drilling resulted in a success of 12.0% in Arkansas, 10.3% in North Louisiana, and 16.8% in East Texas.

The most important exploration and development activity in South Arkansas was within the Smackover limestone trend. In North Louisiana, drilling for Wilcox (Eocene) production accounted for 59% of the total exploratory wells drilled. Much of the activity centered in the updip shallow gas trend of Caldwell, LaSalle, and Winn Parishes. In East Texas, 4 important discoveries were made in the Smackover limestone and 3 from the Cotton Valley Formation. Cherokee Trace field, Upshur County, where both the Smackover and Cotton Valley are productive, appears to be the largest find during the year.
