A University of Utah geophysicist has received private funding for the seventh consecutive year for his research in locating minerals and petroleum with electromagnetic techniques.

Dr. Gerald W. Hohmann says the goal of his computer-aided research is determining what resources lie beneath the earth's surface by measuring electric and magnetic fields at the surface.

"These techniques provide information about the electrical resistivity, which is different for each type of rock. By this means, one can locate sedimentary rocks that may contain oil and gas reserves," says Hohmann.

This year, Hohmann's research is sponsored by Amoco Production Co., Arco Oil and Gas Co., BHP/Utah International, Chevron Resources, Unocal Corp. and CRA, an Australian mining company.
