Core description from GB-1 (Gasbuggy 1) in the northeastern part of the San Juan Basin, Rio Arriba County, New Mexico

The core herein described came from the first test hole drilled for Project Gasbuggy--a project designed to stimulate gas production by the use of nuclear explosives from the Pictured Cliffs Sandstone in the northeastern part of the San Juan Basin, N. Mex. Project Gasbuggy is a cooperative experiment principally involving the El Paso Natural Gas Co., the Atomic Energy Commission, and the U.S. Bureau of Mines. Permission to describe the core from the well was kindly granted by these three organizations.
