Fralick West Field Oil & Gas Data

General Field Information

Produces Oil: Yes Produces Gas: Yes
Geologic Province: East flank Hugoton Embayment of Anadarko Basin
Exploration Method: Subsurface geology
Surface Formation: Quaternary sand dunes
Oldest Formation Penetrated: Arbuckle in SWD well @ NW SW Sec. 28
Drilling Casing Practices: Most wells drilled by Walters and Mull were completed in open hole after coring and drillstem testing. Some of these wells were only cased-hole logged, inasmuch as core information provided more than open hole log in the section. Some wells drilled through pay section, cased through and selectively perforated. There seems to be little difference in performance between the two types of completions. Most wells had sufficient natural productive capacity to produce naturally or after small cleanup acid job.
Electric Logging Practices: When open hole logs where run, they generally were a gamma-neutron-resistivity combination.
Comments: Other shows: Few slight shows in lower Pennsylvanian carbonates

Producing Formation:


MISSISSIPPIAN
(Mississippian System)
Depth Top: 4868 feet
Formation Lithology: Dolomite, fine to very finely sucrose, tan to gray-green, usually more or less silty, with fairly abundant microfossiliferous chert. Production from thin irregular streaks of low permeability in otherwise tight matrix.
Formation Geometry: In the Kansas Oil and Gas Fields book, Vol. V, p. 74 there is a map of this field. The payzone is generally west of the truncation (pinchout) line and absent to the east. In the Warsaw, the porosity is erratic.
Trap Type: Stratigraphic, paleogeomorphic

Oil & Gas Production Information
Produces Oil: Yes Produces Gas: Yes
Drive Mechanism: Drive for this field is probably a combination of gas cap expansion and edge water drive. Formation pressures have been monitored by shut in static fluid levels. These have been observed to drop rather rapidly in the early years, gradually leveling off to approximately 500 psi average for the field (somewhat higher in vicinity of the gas cap and at the areas of water encroachment). An engineering study in May 1968 estimated primary oil recovery for the field at 2,160,000 BO, and recommended unitization for secondary recovery. Primary recovery has far exceeded the 1968 estimate, probably because the drive mechanisms discussed above are more efficient than was realized at that time, and because this reservoir is of higher permeability, homogeneity, and efficiency than is usual for Mississippian dolomites in Kansas.
