Arizona's largest and most important oil field was discovered in early 1967 on the Toadlena anticline in NE. Apache County. This field, Dineh-bi-Keyah, produces from an igneous sill of Tertiary age intruded into rocks of the Pennsylvanian Hermosa Formation. Depth to the oil productive sill varies from 2,800 to 4,400 ft, primarily because of the rugged terrain. Sixteen wells at Dineh-bi-Keyah have produced 6.3 million bbl of oil to Feb. 1, 1969. Three wells in this field have each produced more than 1 million bbl of oil to date. The field is developed on 160-acre spacing. The presently established oil and natural gas production in Arizona is confined to the extreme NE. corner of the State in Apache County. These fields are all located on the large Navajo Indian Reservation. Parts of 2 large and highly contrasting geologic provinces are present in Arizona: the Colorado Plateau province to the north, and the Basin and Range provinces on the south. Some oil potential exists in the Basin and Range portion of Arizona. The complex structure and difficulty in locating specific prospects are the primary obstacles. (15 refs.)
