Salt Complex
By
This salt complex, more than 28 miles long and up to 12 miles wide,
may be part of a much longer salt feature that extends both toward the east
and west. The mother salt bed, of probable Late Triassic-Early Jurassic
age, is presently buried to depths of 40,000 to 50,000 feet, whereas the
tops of the individual domes along the trend rise to within 2,000 to 3,000
feet of the surface.
Production to date on this three-field complex has been in excess of
0.7 billion barrels of oil. Oil reserves are estimated to range from
another 0.75 billion to 1 billion barrels. In addition, significant gas
reserves are present.
Hydrocarbon accumulation occurs in sands of Pleistocene through
Late Miocene age and ranges in depth from 1,000 feet to below 20,000
feet. 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 1967 was approximately 97 million barrels End_of_Record - Last_Page 17--------
