In 1976 there were 52 wells and 13 deep observation holes drilled to explore for and develop geothermal resources in the States of California, Idaho, Nevada, Oregon, and Utah. This was an increase of 27% over the total number of locations drilled in 1975. Of the 52 wells drilled during 1976, 39 (75%) are now considered to have successfully found at least potentially commercial quantities of steam or hot water, 8 are otherwise suspended, and 5 were abandoned. Two new fields were discovered, in the Imperial Valley and Nevada, and four important extensions to production were made at The Geysers. The drilling activity for 1976 is summarized by state and by operator. The total footage drilled was 437,752 feet, which represents an increase of 82,609 feet (23%) over the total footage drilled in 1975. As in 1975, the three operators most active in 1976 were Union, Aminoil, and Republic Geothermal, based on footage drilled.
