Characteristics of discrete and basin-centered parts of the Lower Silurian regional oil and gas accumulation, Appalachian basin: Preliminary results from a data set of 25 oil and gas fields
U.S. Geological Survey Open-File Report 98-216
Appendix S
Moreland oil field (M)
Location: | Wayne (Franklin Twp.) and Holmes (Prairie Twp.) Counties, Ohio |
Discovery date: | 1956 |
Depth (ft): | 3,500 |
Hydrocarbon type and GOR: | Oil and associated gas |
Structural setting: | East-southeast-dipping homocline; possibly influenced by the north end of the Parkersburg-Lorain syncline |
Stratigraphic name of reservoir: | "Clinton" sands; reservoirs dominated by north-south trending, sinuous and elongate sandstone bodies of offshore bar origin |
Trap: | Stratigraphic; updip pinchout of reservoir sandstone |
Porosity: | F ave = 9.55%, range 2.2 to 13.9% |
Permeability: | Kave = 7.27 mD, range <0.01 to 43 mD |
Natural fractures: | Vertical fractures reported in core |
Diagenetic features: | Silica cement most common, local calcite cement |
Water saturation and volume/salinity of produced water: | Sw(ave) = 22.8%, range 9.2 to 95%; reservoir is generally lacking in produced water, all permeable zones are reported to be essentially water free, overlying Newburg zone (400 ft above "Clinton") contains water; Salinity = 200,083 ppm, sample number = 1 |
Gas/water and oil/water contacts: | |
Reservoir pressure: | 1,100 psi (0.31 psi/ft) |
Bottom-hole temperature: | |
Well spacing: | 20 acres per oil well; 80 acres per gas well |
Ultimate production (EUR per well): | The field has produced 2.6 MMBO through mid-1960 |
