"The 5th Annual In-Situ Energy Recovery Technology short course was presented on August 7-8, 1980 at the AMFAC Hotel in Albuquerque, New Mexico. This year we had over 100 attendees, counting guests and speakers. The new course format was well suited to the needs of the majority of attendees. The new approach was to devote the first morning period to an overview and to the basic generic technology of in-situ processes; followed by, three half-day sessions covering underground coal gasification, in-situ oil shale extraction, and other in-situ energy recovery technologies such as geothermal, solution uranium mining, and unconventional gas recovery."
