In 1963, there were 3,992 wells drilled in the Permian Basin. This represents a 14% decrease from 1962. Exploratory tests averaged 32% and development drilling 88% as being successful. Exploratory success gained 4% while development remained the same compared to the previous year. Of the 359 successful exploratory tests drilled during 1963, 61 were considered significant based on reserves, potential productive area and geological significance. Geophysical activity increased 6% in crew-weeks for seismic; while gravity decreased 57%. The Delaware basin led the province in seismic activity.

The Central Basin platform was the most active geologic feature in drilling activity while having several promising discoveries. San Andres, Wolfcamp, and Pennsylvanian activity in the north part of the Northwestern shelf resulted in establishing interesting new reserves. Deep Pennsylvanian gas exploratory drilling continues in western Eddy with discoveries stimulating interest. Two promising oil discoveries were completed on the Ozona platform indicating a sizable reserve. Encouraging discoveries were plentiful in the Midland basin from new-field wildcats and drilling deeper in shallow pay fields. Deep drilling is increasing in the southeastern part of Delaware basin where major gas reserves are indicated. The Val Verde basin continues to increase its gas reserve through deep explora ory drilling. Pecos County led the Permian Basin area in number of discoveries, and now has the world's deepest production.

Leasing was active in basin areas. A Strawn oil discovery in central Crockett County stimulated leasing there and into Sutton County. The 47th Texas University Land Auction brought the University $2,950,000 for 50,621 acres. Leasing in western Eddy County, New Mexico, was active based on Pennsylvanian gas discoveries.
