Title	Texas Agreement State Report - Abandoned Well Logging Source
Event Description	On August 30, 2004, Schlumberger Technology Corporation was logging the Allar #1 well, operated by Famcor Oil, Inc., API # 42-407-30612, located in San Jacinto County, Texas. The well logging tool string became stuck during logging operations in the 11,998 foot well. The source string is below 3,319 feet of drill pipe stuck in sand-shale and sand-shale interfaces. Multiple attempts at recovery were conducted between 10/22/2004 and 10/29/2004. The Licensee notified the Agency of probable abandonment on 10/28/2004. The tool string contained two sealed radioactive well logging sources. The Licensee has not informed the Agency of the manufacturer of the sources. However, the 16 Curie Am-241/Be Neutron source, Model NSRF, Serial No G5053, is stuck and cemented in place at 8,326 feet [mine depth (MD)] , and the 1.7 Curie Cs-137 Density source, Model GSRJ, Serial No. Al 927, is stuck and cemented in place at 8,339 feet MD. Both sources were last leak tested on April 3, 2004, and were current on the date the sources became stuck in the well bore. Two-hundred feet of red oxide dyed cement is spotted on top of the stuck drill pipe from 4,984 feet to 4,750 feet. A used drill bit was placed as a deflection device at 4,750 feet. An additional 208 feet of cement was place on top of the drill bit, with the top of the cement located at 4,550 feet. The job was completed on October 30, 2004. A required plaque was ordered on November 19, 2004, and will be placed on the well head when received. Texas Incident No. I-8185
