Abstract

A subsurface earth formation or petroleum reservoir, either previously or presently producing petroleum hydrocarbons, such as oil and natural gas, is analyzed. From production data, the actual fluid flux of the hydrocarbons to each well penetrating the formation is obtained. By analyzing the actual fluid flux in the formation, areas in the formation where little if any hydrocarbon flow occurred are located. The areas so located are likely to contain dormant oil, which may be produced by new wells.
