Gasbuggy Postshot Investigations in GB-ER
Abstract
Postshot reentry of the emplacement hole began on December 12, 1967, and terminated at a total depth of 3,916 ft on January 10, 1968. The hole below 3,000 ft was drilled with water and gel because of wet hole conditions. Two voids (from 3,856 to 3,862 ft and from 3,907 to 3,916 ft) and a number of casing breaks encountered. Subsequent geophysical logging and short term flow tests suggests that the lower void could be considered part of the "chimney," but that it is only poorly connected with the major void volume. It is also felt that the chimney geometry is strongly influenced by horizontal fracturing, so that the chimney top is a poorly defined region of sags, or slump blocks. It must be recognized, however, that these conclusions are based on minimal data, and new information may alter them.
