Show Rulison Drilling Reaches 6,520 Foot Depth DrilJjig of cement from the exploratory hole casing at the Project Rulison site near Grand Valley, Colorado has reached 6,520 feet. As of nocn, Tuesday, May 5, 1970, operations were underway under-way to niill out the casing liner and milling was continuing con-tinuing at about 5.870 feet. Drilling to penetrate the zone of broken nx?k (chimney) (chim-ney) in the natural gas formation for-mation fractured by a nuclear nu-clear explosion started April 28. Neither natural gas prc-s jlire nr rn&oacti.v'ity has-been has-been encountered as of Tuesday, although both are expected when chilling reaches reach-es the chimney area at alxmt 8,030 feet. Project engineers en-gineers expect drilling to be completed late in June. Then after sampling and analysis of the natural gas with highly high-ly sensitive racfiation de-tectiimi de-tectiimi instruments, production produc-tion testiirg will begin. The gas produced during the production Will be monitored mon-itored constantly for radioactivity. radio-activity. In conformance with the Atomic Energy Commission and Federal Radiation Ra-diation Council standards, the gas, as it is produced, will be flared (burned) from a stack at the Rulison site. Rullison is a joint government-industry project to determine de-termine the technical and economic feasilil'ity of stimulating stim-ulating natural gas production produc-tion by nuclear fracturing of rx-k formations (hat cannot otherwise be produced. The project participants ,-.re Austral Aus-tral Oil Company. Inc., Houston; Hous-ton; the Atomic Energy Commission, Com-mission, and tlie Department of (Hie Interior's Bureau of Mines. |
