| Abstract | A steady state divided bar and a thermistor probe have been used to obtain thermal conductivity measurements of rock core samples from six boreholes and temperature measurements from two boreholes in northwestern Pennsylvania. When combined, these measurements yield uncorrected heat flow values for Clarion and Venango Counties of 1.73 HFU and 1.44 HFU respectively. Fully corrected for the effects of a secondary recovery experiment, the Alleghany River, Pleistocene climatic variations and the effects of topography, the heat flows are 1.84 HFU and 2.00 HFU. This is the highest heat flow reported in the Alleghany Plateau. A temperature gradient map constructed from 439 reported bottom hole temerature measurement of oil and gas wells in four states and heat production measurements for 41 samples of basement material indicated the above average heat flow is due to a shallow heat source. |
