ABSTRACT

The Misener Sandstone is distributed over approximately 25% of the area included in T15-16N, R6-7E, Lincoln and Creek Counties, Oklahoma. This sandstone can be described as a medium to fine grained ( to 1/8 mm), subangular to subrounded sandstone which is cemented by dolomite and minor amounts of quartz cement. Withint he area the rock changes from 90-95% quartz grains to more than 50% dolomite with "scattered" quartz grains "floating" randomly within the matrix.

Definite relationships between the presence or absence of the Misener and the underlying strata, whether they be Hunton or Syvan, are present in the area. The most significant relationship is that the Misener infills erosional channels in the subjacent strata. The probability of encountering the sand for a given thickness of the underlying strata can be computed.

Two depositional environments for the Misener are proposed. One is a fluvial channel deposit in the northeastern two-thirds of the area where the Misener unconformably overlies the Sylvan Shale. here the sand is characterized by less than 10% cement and no glauconite. The other environment is a tidal flat which is characterized by the sand grains being "scattered" in a dolomite matrix (greater than 50%) deposited in tidal channels etched into the underlying Hunton. In this area the sand contains glauconite.

Production from the Misener in this area has been from only one well. This well produced a total of 38,555 barrels of oil over an eleven year period. The Misener in this well is 8 feet thick. Numerous shows of oil have been reported fromt he Misener in wells in the study area and drill stem tests have been reported in some of them.
