Liberal-Light Field Oil & Gas Data

General Field Information

Produces Oil: Yes Produces Gas: Yes
Exploration Method: The discovery of the Liberal-Light field was drilled on the strength of one man's faith that oil was present under a specific lease. The Lansing-Kansas City production was discovered while drilling an offset well to a Morrow sandstone producer.
Drilling Casing Practices: Nearly all wells are drilled through the top 100 or 150 feet of the Mississippian Section. Pipe is set through the Morrow section and the casing perforated opposite the producing sands. Where permeability and porosity permits a high natural gas flow the well is completed after a light mud acid wash or is completed naturally. When the permeability is low and the initial volume is low, the producing sand is then hydraulically fractured to increase the flow of gas. The Lansing-Kansas City oil reservoir was completed as a naturally flowing well.
Comments: The Mississippian reservoirs are not mentioned in KOGF, Vol. II.
Discussion: As of July 1959, the average cost to drill a 6300 foot dry hole was about $64,000. Producing wells of the same depth averaged $100,000, which includes the cost of drilling, casing, tubing, well head controls, separator and tank battery.

Producing Formation:


LANS.-K.C.
(Lansing - Kansas City Supergroup)
Formation Lithology: Lansing-Kansas City reservoir is a cream to buff colored fine crystalline, dolomitic limestone.
Trap Type: The Lansing-Kansas City reservoir is a stratigraphic type trap. This trap is formed by a lens of porosity that feathers out in all directions from the bore hole into nonporous, impermeable limestone.
Continuity of Reservoir Rocks: The Lansing-Kansas City limestone member that is productive in the Lansekan Oil, Woods 1, 15-175-10191, 36-34S-32W is a traceable limestone that lacks reservoir development in all nearby wells.

MORROW SANDSTONE
(Upper Kearny Member)
Depth Top: 6005 feet
Formation Lithology: The Morrow sandstones are colorless, fine to medium grained, subangular to subrounded sand grains with either limestone or shale modifiers.
Trap Type: The reservoir rock is sandstone. Type of trap is stratigraphic. Regional structure consists of homoclinal dep on all beds toward the south-southeast or towards the trough of the Anadarko Basin. Regional dip has been interrupted by minor uplist that formed local structures, the more prominent structural features being the Keyes Dome and the Kismet High. Oil and gas accumulations in the Morrow sandstones occur independently of regional or local structure. It is possible that the Mississippian erosional surface may have influenced sandstone deposition and therefore, indirectly influenced acccumulation. The Morrow sandstones occur as lenses that vary greatly in areal extent and are found throughout the Morrow section. Besides varying in areal extent the reservoir characteristics o fthe sands are quite variable. Permeability and pososity are modified by limestone or shale content in the sandstone. These modifiers form permeability barriers that assist in trapping both gaseous and liquid hydrocarbons. The lenticular nature of the sandstones combined with the variability of reservoir characteristics makes the Morrow sandstone ideal for the formation of stratigrapic type traps.
Continuity of Reservoir Rocks: Sandstones in the Morrow section are lenticular in nature and vary in areal extent. Because the field is essentially a dry gas field, well space in one well per 640 acres. Such wide spacing makes it impossible to determine exactly the areal extent of any sandstone lens.

Water Production: Initially the Morrow wells were completed water free. As the wells near depletion, however, the reservoir pressures are reduced and interstitial waters are released into the reservoir. The volume of water thus released is very minor.
Proven Production: 5840 acres Production Well Spacing: 640 acres
