Logs of stratigraphy, lithology, gamma, neutron porosity, density, and bedding orientation in the Cherry Flats test hole, Tioga County, Pennsylvania.

Under contract with the Pennsylvania Department of Conservation and Natural Resources (PADCNR) Bureau of Topographic and Geologic Survey (BTGS), ARM provided down-hole geophysical services as part of the integrated analysis of core, geophysical logs, gas isotopes, and specific-depth water quality samples from the Cherry Flats test hole was used to characterize the stratigraphy, water-bearing zones, and groundwater quality at a site in southern Tioga County, Pennsylvania.  The study was completed as a cooperative effort between the Pennsylvania Department of Natural Resources, BTGS and the U.S. Geological Survey (USGS).  The multi-disciplinary characterization of the test hole provided information to aid the bedrock mapping of the Cherry Flats 7.5-minute quadrangle by BTGS, and to help quantify the depth and character of fresh and saline groundwater in an area of shale-gas exploration.
