Title	Agreement State Report Involving Lost Well Logging Source
Event Description	After performing services to determine the oil/water contact interface and the gas/oil interface levels the wireline with the source was being retracted. The wireline was attached to 1 11/16" tool in the salt dome. During retraction, the source evidently got hung on entry to the hole to the surface. It is felt that the crew was inattentive or possibly did not use proper procedure. The 'stuck' source broke loose of the wireline at the established weak point of connection between the tool and the wireline. Retrieval of the source is deemed unrecoverable. This is the second incident of this type in the same field. The source is a Gulf Nuclear, Model CSV-F74, Cs-137, 100 millicurie source. The probable depth of this source is estimated at approximately 4,000 feet. Investigation on site continues. A written report will be submitted to this Agency [Texas Department of Health]. Texas Incident No.: I-8142 Event Location: Bryan Mound Strategic Petroleum Reserve, Brazoria County, Texas, Well # BM 104B
