Pleasant Prairie Field Oil & Gas Data

General Field Information

Produces Oil: Yes Produces Gas: Yes
Exploration Method: The discovery well was drilled by Helmerich and Payne on a large block of acreage held by Permian Gas Production, with the intention of using it as a replacement well in the event deeper production was not established. Subsequent tests were drilled on Winfield (Permian) structural highs.
Completion Practices: Wells are completed by running casing through the pay zones, perforating and acidizing with 1000 gallons mud acid.
Comments: From KS Geo Soc, Vol. 2: Casing is set at approximately 830 feet. From Roby, 1961: Field is 7.5 miles long and 2.5 miles wide.

Producing Formation:


LANSING-KANSAS CITY
(Lansing - Kansas City Supergroup)
Formation Lithology: The reservoir is a limestone, fine crystalline, cream-gray, good oolicastic porosity with a thickness of approximately 12 feet.
Trap Type: Stratigraphic entrapments in both the Marmaton and the Lansing-Kansas City are controlled by porous oolicastic limestone lenses. A commercial reservoir has not been definitely established in the field, however, the White Eagle, USA 'B' 1-14, NE NE SW, Section 14-26S-35W is producing oil from an oolicastic zone within the Lansing-Kansas City. These porous oil-bearing lenses appear to cover little areal extent and are controlled by definite porosity pinchouts between wells.
Continuity of Reservoir Rocks: Production is limited to one well in 26S-35W-14.

MARMATON

Trap Type: Stratigraphic entrapments in both the Marmaton and the Lansing-Kansas City are controlled by porous oolicastic limestone lenses. No oil production has been established from the Marmaton section, however, a porous oolicastic limestone lens at the top of this section has indicated (by DST) commercial oil possibilities in the McKnab & Lindsay, Kuhn_Devlin 8-19. These porous oil-bearing lenses appear to cover little areal extent and are controlled by definite porosity pinchouts between wells.

Oil & Gas Production Information

Producing Formation:


MORROWAN
(Upper Kearny Member)
Depth Top: 4959 feet
Formation Lithology: The reservoir is a limestone, buff-brown, fine-coarse crystalline, fossiliferous, vuggular to fracture type porosity, with about 5 to 10 feet net effective pay.
Trap Type: Oil is produced from a stratigraphic entrapment in a buff-brown coarse crystalline, fossiliferous, sandy, porous limestone. It is usually found flanking local highs and appears to wedge out up dip and shale out down dip. An erratic sand development occurs at the base of the Morrow and directly overlies the older Mississippian; commercial oil production, however, has not been established in the sand facies.
Continuity of Reservoir Rocks: There are not enough wells producing from this reservoir to determine extent or continuity.

MISSISSIPPIAN (ST. LOUIS)
(St. Louis Limestone Formation)
Depth Top: 5041 feet
Formation Lithology: The reservoir is a limestone with one to three highly oolitic and algal porosity zones developed. The thickness is very erratic, ranging from 5 to 38 feet. Fracture porosity has been found in well cores at the top of the St. Louis formation and may extend downward 30 feet.
Trap Type: The reservoir is a combination stratigraphic and structural trap. It is a regional Mississippian nose that plunges south-southeast. The stratigraphic conditions that control the accumulation of oil are erratic porosity zones within the St. Louis formation. These zones vary in number, thickness and effective porosity and appear to limit the extent of the field by porosity pinchouts. Two dry holes, White Eagle, Citizens Building & Loan 1, C NE NE, Section 25-26S-35W and White Eagle, Jones 0-30, C SW NW, Section 8-27S-34W, suggest early Pennsylvanian or late Mississippian faulting on the west side of the field. The truncation of the porous zones against the fault face serves as a barrier to prevent the oil migrating to regionally higher Mississippian rocks to the west and northwest. The uppermost section of Mississippian (Ste. Genevieve) has had shows of oil in numerous field wells; the Ste. Genevieve, however, has not produced commercially. This zone consists of an erratic facies change from a sandy finely oolictic limestone to a dense very find grained calcareous sandstone. As a rule, this zone has little or no porosity or permeability. Its thickness ranges from zero to 22 feet. At the present stage of development it is difficult to determine whether the anticlinal features actually control the entrapment of oil. These features do affect to some extent the variation in gravity of the oil and the producing water percentages in the field. As depletion occurs and flooding (artificial or natural) begins, the structurally higher wells will have higher oil recoveries. To date, there is 100 feet of structural relief on the producing St. Louis horizon; the effective porosity thickness, however, is the factor controlling the individual capabilities of the wells. The upper portion of the St. Louis formation, as shown by well cores, has variable amounts of fracturing, which may extend to a depth of 30 or more feet.
Continuity of Reservoir Rocks: The continuity of the reservoir is erratic throughout the field. Producing wells have from one to three porous zones developed and these vary in thickness, porosity and permeability. Gas and water contents are dependent upon porosity and permeability encountered; i.e., water saturation and gas quantity increase with increased porosity. The only persistent porosity in the field is in the lowermost producing zone (C zone from cross section), which is approximately 75 feet below the top of the St. Louis formation. This zone is present in all wells throughout the field.
