ABSTRACT:
A method for indicating the proximity of a hydrocarbon reservoir by measurements of thermal gradients in dry holes. Due to the lower thermal conductivity of hydrocarbon-containing rock, the thermal gradients within such rock are abnormally high when compared to normal subsurface thermal gradients and the anomaly extends well beyond the boundaries of the reservoir. Geothermal gradients are measured along the entire length of deep boreholes, which have proved to be dry, or in shallow test boreholes. A comparison of the shape of such gradient curves to theoretical curves indicates the presence of a hydrocarbon deposit spaced laterally from a deep dry hole or below a shallow surface test hole.
