The state of Arizona is divided into three parts according to its oil and gas possibilities based on present knowledge. This paper gives only a brief mention of the Basin and Range provinces in the southern and western parts of the state and concentrates on the possibilities in the Plateau Province in the northern part.
The major objective formations in the Plateau Province include the Ft. Apache member of the Supai formation (Permian), Hermosa formation (Pennsylvanian) and the Martin formation (Devonian). The presence of a Permian Salt basin in central eastern Arizona may open reef possibilities in the Supai. The Pennsylvanian formations have been disappointing due to the lack of good reservoir beds. Devonian possibilities appear greatest south of the Navajo-Hopi Indian Reservation and in general south and southwest of Holbrook.
The presence of old granite highs and ridges has proved exploration to be dangerous; however, this may be solved by a combination of aerial magnetometer, seismograph, and detailed stratigraphic studies.
