Michael H. Trippi
Michael Trippi is a Geologist with the USGS Geology, Energy & Minerals (GEM) Science Center in Reston, VA.
Mr. Trippi began his professional career as a geologist with the USGS in April 2000, working primarily on investigations and assessments of coal (including coal bed methane in the Powder River and Appalachian Basins, and coking coal of the United States) and petroleum systems (including Devonian shale gas and oil shales of the Appalachian Basin). He continues to work in these same areas to date.

Thermal maturity of northern Appalachian Basin Devonian shales: Insights from sterane and terpane biomarkers
To better estimate thermal maturity of Devonian shales in the northern Appalachian Basin, eleven samples of Marcellus and Huron Shale were characterized via multiple analytical techniques. Vitrinite reflectance, Rock–Eval pyrolysis, gas chromatography (GC) of whole rock extracts, and GC–mass spectrometry (GCMS) of extract saturate fractions were evaluated on three transects that lie across previouAuthorsPaul C.

Geographic information system (GIS) information may facilitate energy studies, which in turn provide input for energy policy decisions. Prior to this study, no GIS file representing the occurrence of coal-bearing units in India or Bangladesh was known to exist.

Between 1999 and 2007, the U.S. Geological Survey (USGS) investigated coalbed methane (CBM) resources in the Wyoming portion of the Powder River Basin. The study also included the CBM resources in the North Dakota portion of the Williston Basin of North Dakota and the Wyoming portion of the Green River Basin of Wyoming.

This report contains a simplified provisional correlation chart that was compiled from both published and unpublished data in order to fill a need to visualize the currently accepted stratigraphic relations between Appalachian basin formations, coal beds and coal zones, and key stratigraphic units in the northern, central, and southern Appalachian basin coal regions of Alabama, Tennessee, KentuckyAuthorsLeslie F. Ruppert, Michael H. Trippi, Ernie R. SlucherGeologic controls on thermal maturity patterns in Pennsylvanian coal-bearing rocks in the Appalachian basin
Thermal maturation patterns of Pennsylvanian strata in the Appalachian basin were determined by compiling and contouring published and unpublished vitrinite reflectance (VR) measurements. VR isograd values range from 0.6% in eastern Ohio and eastern Kentucky (western side of the East Kentucky coal field) to greater than 5.5% in eastern Pennsylvania (Southern Anthracite field, Schuylkill County), cAuthorsLeslie F.

U.S. Geological Survey (USGS) regional geologic cross section C-C' (Ryder and others, 2008) displays key stratigraphic intervals in the central Appalachian basin. For this cross section, strata were correlated by using descriptions of well cuttings and gamma ray well log traces.
