Hawks Field Oil & Gas Data

General Field Information

Produces Oil: Yes Produces Gas: Yes
Geologic Province: Hugoton embayment on the north flank of the Anadarko Basin
Exploration Method: Re-examination of subsurface geology leading to the reopening of an old dry hole.
Drilling Casing Practices: Since this well was drilled to the Simpson, casing was set through the Morrow sandstone and the pipe perforated opposite the gas pay. Originally the Morrow sandstones were treated with acid; fracturing, however, is now the accepted method of well stimulation. (KOGF, Vol. II, 1959)
Comments: This field extends into Beaver County, Oklahoma: T6N R21E Central Meridian, Sections 12 and 13.
Discussion: The average cost of a dry hole was $64,000. Costs for a completed well varied from $82,000 - 128,000 and averaged $100,000.

Oil & Gas Production Information
Produces Oil: Yes

Producing Formation:


MORROWAN SANDSTONE
(Upper Kearny Member)
Depth Top: 5927 feet
Formation Lithology: Rock type is sandstone. Rock modifier is calcium carbonate as a cementing material. Thickness of pay for the discovery well, Lofland-Hawks 1, 15-175-00103-0001, is 18 feet.
Trap Type: Trap Type: Stratigraphic. The Morrowan rocks dip gradually into the Anadarko Basin trough with no local structure expression. The Reservoir is a lenticular porous, permeable sandstone of limited areal extent. The lenticularity of the sand is the dominant cause of gas accumulation.
Continuity of Reservoir Rocks: The sandstones are lenticular and vary greatly in their areal extent.
