AMOCO STARTS ANOTHER W. TEXAS INFILL PROGRAM

Amoco Production Co. has started its second infill drilling program in as many months in West Texas. This week, Amoco was to have spudded the first of 19 wells in Gaines County, Tex., to test feasibility of converting 40 acre, five spot waterflood patterns to 20 acre, line drive well spacing. Last month, Amoco began a 37 well infill program in eastern Levelland field, Hockley County, Tex. (OGJ, Oct. 8, p. 30).

Amoco Production Co. has started its second infill drilling program in as many months in West Texas.

This week, Amoco was to have spudded the first of 19 wells in Gaines County, Tex., to test feasibility of converting 40 acre, five spot waterflood patterns to 20 acre, line drive well spacing.

Last month, Amoco began a 37 well infill program in eastern Levelland field, Hockley County, Tex. (OGJ, Oct. 8, p. 30).

For the Gaines County project, Amoco will drill seven oil wells and 12 water injectors in the north central and southeastern sectors of the 6,798 acre Cedar Lake Unit to an average 4,900 ft in Permian San Andres. It expects to complete the $5.9 million pilot program by yearend.

Amoco will use pilot data to determine well spacing in the unit, which presently has 135 producers and 167 water injectors. The company has a 95.9% interest in the unit, and other interest owners include Chevron Corp., and Moncrief Oil Operating Co. and Snyder Oil Co., both of Fort Worth.

"While modest in its scope," said Amoco Production Vice Pres. Dale Gilliam, "the Cedar Lake project represents exactly the kind of effort necessary to recover additional oil from the state's mature provinces."

In two Cedar Lake infill programs in 1987-88, Amoco drilled 118 wells and converted 102 to injectors after oil production had dropped to about 2,500 b/d after peaking at 7,300 b/d in the early 1970s.

The program revived production to its present 6,200 b/d.
