This salt complex, more than 28 mi long and up to 12 mi wide, may be part of a much longer salt feature that extends both east and west. The mother salt bed, of probable Late Triassic-Early Jurassic age, is buried at depths of 40,000-50,000 ft, whereas the tops of the individual domes along the trend rise to within 2,000-3,000 ft of the surface.

Production to date on the three-field complex has been more than 0.7 billion bbl of oil. Oil reserves are estimated to range from 0.75 billion to 1.0 billion bbl. Significant gas reserves also are present.

Hydrocarbon accumulation occurs in sands of Pleistocene through late Miocene ages and ranges in depth from 1,000 to below 20,000. A wide variety of traps is found, including supradomal arching, shale and salt truncations, stratigraphic traps, and those resulting from faults.

Production was established on this complex in 1933. The total hydrocarbon production for 1968 was approximately 99 million bbl.
