section - Appalachian Plateau surface anticline
1 BRADFORD SANDSTONES - turbidity deposits (in our area). Best sands deposited in paleo-bathometric lows where marine currents were continuations of fluvial systems that emptied into the basin.
EUR: 100 - 225MMcf/well
2, 3, 4 MARCELLUS SHALE - deposited in restricted basin. High in kerogen. Natural fractures are essential for reservoir characteristics. It may be analogous to the Barnett Shale.
5, 6, 7, 8 HUNTERSVILLE CHERT & ORISKANY SANDSTONE - (in our area) 150 feet of thickness. Brittle. Reservoir is dependent on natural fractures from folded "pop-up blocks".
EUR: up to 16Bcf/well
9, 10 BALD EAGLE SANDSTONE - thick, brittle rock. When differentially compacted over growth faults, natural fractures provide good reservoir characteristics.
11, 12 TUSCARORA SANDSTONE - same comments as Bald Eagle.
13, 14, 15 UTICA SHALE, TRENTON LIMESTONE, BLACK RIVER DOLOMITE - natural fractures enhanced by basement derived hydrothermal solutions may create high quality reservoirs. Theorized to be numerous in occurrence, the reality is that they may be narrow and very hard to find with a drill-bit.
EUR: 10Bcf or more/well
16 GATESBURG SANDY DOLOMITE - future?
17 BASAL CAMBRIAN SANDSTONES - future?
