This paper discusses the processes that need to be taken to complete a study on the Lehigh field in Marion County, Kansas, for potential reservoir resources and paleogeographic interpretation of the major unconformity of the Late Mississippian-Early Pennsylvanian. The Lehigh field is located east of the Nemaha uplift. Overall the field is small with nine wells drilled that produced and four wells of which still remain producing and unplugged to date. The total oil accumulation for the field is 80,913 barrels of oil and 222,765 million cubic feet of gas. The Lehigh field was discovered by AndersonÐPrichard & Dieter in 1953 with the drilling of the well named Wassmiller 1.  Wassmiller 1 is located NW NW SW sec. 23, T. 19 S., R.1 E. and tested about 2.5 billion cubic feet of gas (Jewett, 1954). The wells in the field predominantly produce oil and gas from Mississippian Warsaw/Osage. The main purpose of the study is to prepare prospecting for potential reservoirs and to look at the major unconformity, of the Late Mississippian-Early Pennsylvanian, by the subtle differences of thicknesses in the Mississippian Warsaw/Osage and the Cherokee Group that overlies it. Methods in studies will include analysis of well logs and looking at 2-D seismic, well sample cuttings, and reservoir reserve studies in secs. 13, 14, 15, 22, 23, and 24 of T. 19 S., R. 1 E. Using this information, structure and isopach maps will be created that are related to the analysis of the Mississippian formations.
