U.S. Geological Survey Open-File Report 98-216
Appendix M
Kantz Corners gas field (KC)
| Location: | Crawford (Cochranton and Geneva 7½ min. quads) and Mercer (Hadley and New Lebanon 7½ min. quads) Counties, Pennsylvania |
| Discovery date: | 1977 |
| Depth (ft): | 5,100 to 5,200 |
| Hydrocarbon type and GOR: | Nonassociated gas |
| Structural setting: | Regional southeast-dipping homocline with local anticlinal noses |
| Stratigraphic name of reservoir: | Medina Group (Grimsby Formation and Whirlpool Sandstone) |
| Trap: | Probable water-block mechanism; no updip pinchout of sandstone reservoirs |
| Porosity: | Grimsby Formation: F
ave (log) = 6.5%, range 5 to 11.5%; F ave
(core) = 4.9%, range 4 to 6.5% Whirlpool Sandstone: F ave (log), range 4 to 5.9; F ave (core) = 3.9%, range 2.7 to 5.4% |
| Permeability: | Grimsby Formation: Kave = <0.1
mD, range <0.1 to 0.64 mD Whirlpool Sandstone: Kave = <0.1 mD; K = 0.0156 mD also reported |
| Natural fractures: | Natural fractures are the probable cause of a 2.7 mD zone in a core of the Whirlpool Sandstone |
| Diagenetic features: | |
| Water saturation and volume/salinity of produced water: | Sw(ave) = 34.8% in nearby Geneva gas field; Salinity(ave) = 257,000 ppm, range 210,000 to 310,000 ppm, sample number = 5 |
| Gas/water and oil/water contacts: | |
| Reservoir pressure: | 1,182 psi (0.21 psi/ft) |
| Bottom-hole temperature: | 112°F |
| Well spacing: | 80 acres |
| Ultimate production (EUR per well): | |
