Geochemical Exploration For Gas-Charged, Trenton/Black River Hydrothermal Dolomite, New York DIRECT GEOCHEMICAL derived a robust multi-component geochemical model to explore for gas in Trenton Black River hydrothermal dolomitized breccia reservoirs in the Appalachian Basin of New York State. Geochemical studies at Glodes Corner and Terry Hill South gas fields were funded by the New York State Energy Research and Development Authority (NYSERDA). In the case of the Terry Hill South, there is a spatial correlation of thermally desorbed iso-butane, iso-pentane, iso-hexane and ethene with the surface projection of the gas field.

Ethene Z-scores superimposed on iso-C4-C6 factor scores. The hydrocarbons were thermally desorbed from soils collected along roads that cross the 9000-foot deep Terry Hill South gas field in Chemung County, New York.

Ca-Mg-Sr-Pb-Zn-Tl factor scores superimposed on iso-C4-C6 factor scores. This metal factor probably reflects Mississppi Valley Type mineralization along the cross-cutting fault.

Normal hexane superimposed on iso-C4-C6 factor scores. Note the spatial correlation of hexane with the cross-cutting fault.
