Title: Developments in West Texas and Eastern New Mexico in 1977

Author(s): Frank L. Constant, Ray L. Chappelle (2)


A total of 4,900 wells was drilled during 1977 in CSD Districts 13 (eastern New Mexico) and 26 (West Texas). This was an increase of 10.4% from the 1976 figures. Exploratory drilling was at its highest level since 1959. Production declined 3.3% during this same period, despite a 12% increase in development drilling.

The exploratory success rate was 33.6% overall, a decrease of 1.2% from 1976. Of the 308 completed wildcats, only 36 ranked as high as the "D" classification established by Lahee.

There was a 4.9% increase in geophysical activity. New Mexico recorded a decline, particularly in Lea County (43.8%), but Texas had a 7% gain.

Morrow gas prospects experienced a doubling of bonuses in eastern New Mexico and leasing was active for carbon dioxide prospects in northeastern New Mexico. The southern part of the Delaware basin in Texas had an increase in both price and competition for leases. University Lands average cost per acre increased 90.6%.
