Title: Development in Upper Gulf Coast of Texas in 1971

Author(s): John R. Lewis (2)


Exploration for oil and gas in the Upper Gulf Coast of Texas declined in 1971. Exploratory drilling decreased 28%, successful completions were down 6%, and seismic exploration was down 75 crew weeks from the 1970 totals. Development drilling increased from 492 wells in 1970 to 535 in 1971, thus reversing a 3-year trend. Successful completions were down slightly, from 73 to 72%. Exploratory drilling emphasis shifted from the Oligocene trend to the Eocene trend, whereas geophysical emphasis, after heavy concentration on the Cretaceous trend in 1970, centered in the Oligocene trend in 1971. The year's most numerous discoveries were in the Eocene trend, but the most significant were in the Miocene trend.
