Unocal's Spirit Energy 76 makes gas discoveries in Bobcat Run field, Texas

Sugar Land, Texas, Jan. 21, 1998 - Spirit Energy 76, Unocal Corporation's Lower 48 exploration and production business unit, today said that a fourth exploration well has discovered gas and gas condensate in the Bobcat Run field in Orange County, Texas.

The exploration wells discovered gas and condensate in a formation known as the Hackberry. The Manuel Heirs #1 well tested 2.1 million cubic feet of gas and 76 barrels of condensate through a 12/64-inch choke from perforations between 8,022 and 8,042 feet in late December 1997.

In 1996, Spirit Energy 76 made its first discovery in the Hackberry with the Unocal B.E. Quinn #2 which flowed 2.7 million cubic feet of gas and 64 barrels of condensate through a 14/64-inch choke from perforations between 7,774 and 7,784 feet.

In 1997, the Sid Johnson Mineral Development #1 well tested at a daily rate of 3.5 million cubic feet of gas and 105 barrels of condensate through a 14/64-inch choke from perforations between 8,504 and 8,530 feet. The B.E. Quinn #3 well subsequently tested at a daily rate of 3.2 million cubic feet of gas and 65 barrels of condensate through a 16/64-inch choke from perforations between 8,329 and 8,432 feet.

The three wells have produced 2.75 billion cubic feet of gas and 48 thousand barrels of gas condensate to date. Spirit Energy 76 is operator and has approximately 30 percent working interest in the new discoveries. Spirit Energy 76 holds varying interests in approximately 10,000 acres in the Hackberry trend.

Spirit Energy 76 employs approximately 1,300 people and operates 300 offshore platforms and approximately 2,700 active wells in 355 fields in the United States.

Unocal is a leading global energy resource and project development company, with major oil and gas exploration and production activities in Asia and the U.S. Gulf of Mexico.
