South Timbalier Block 295 field (Figure 1 ) was discovered in 1984; production began in 1989 ( Mason, 1992 ). Production is from stacked...

... Island, Timbalier Bay, and Venice or West Bay salt domes. The four western domes are closely related in genesis. A large up-to-the-basin fault trends northeast from Dog Lake to Four Isle then east to Bay St. Elaine and south to Lake Pelto. The western end of the fault may be traced seismically...

... from 1970. This surge in activity is the result of rapid evaluation of the federal acreage acquired in the December 1970, West Gulf sale. There were 179 tests drilled by 21 separate operators on the new leases. With few exceptions, these tests were plugged and abandoned or suspended, and very little...

The lower pressures in the normally pressured zone are masked by the high mud weights required to hold the upper, higher pressures but can be detected by the proposed method. Fig. 3...

For example, South Pass Block 24 field has produced 325 billion cu ft of gas and 246 million bbl of oil. Gulf Coast production...
