3D SEISMIC SURVEY PAYS OFF AT NEVADA DRILLSITES

Independents report glowing success from the first 3D seismic survey in Nevada's Railroad Valley. Apache Corp., Houston, and Balcron Oil, Billings, Mont., a division of Equitable Resources Energy Co., Pittsburgh, have completed Devonian Guilmette oil wells in recent weeks on locations picked with 3D seismic data. The wellsites are about 1 mile apart in Nye County, where a group led by the two companies acquired an 11 sq mile 3D seismic survey in December 1992 and January 1993. Processing
