Title	California Agreement State Report
Event Description	The following information was obtained from the California Department of Health Services, Radiologic Health Branch, Granada Hills (transmitted text in quotes): Licensee reported to Radiologic Health Branch-Granada Hills (RHB-GH) that on 3/7/05 two well-logging sealed sources became stuck in a well bore at a depth of 9137 feet (top of tool string). Sources are ~35-45 feet below that. The sources involved are a 1.5 Ci Cs-137, GSR-J 1958, source and a 16 Ci AmBe-241, NSR-F 1441, source, nominal activities. For the last day the 'fishing' company, Baker Hughes, has been attempting to retrieve the sources which became detached [on] 3/7/05, [at] ~2200 [hrs. PST]. They will continue to do so but, if that's not successful, it's appearing as if the sources will be deemed irretrievable. This occurred on the 'Aera Ventura Avenue' well site, Ventura County, CA. The well is designated 'McGonigle 39.' If deemed irretrievable, the well will likely be sealed in place with a cement plug. Licensee will provide further details shortly and follow with written report. California Incident Number 0510# 030805.
