| Title | Mississippi Agreement State Report - Stuck Well Logging Source |
| Event Description | The State provided the following information via email:
[The State] received notification on 6-5-06 from Schlumberger that they had logging tool stuck in the Patterson #2 exploration well located at Midway Dome, Lamar County, Mississippi. Logging tool containing a 1.7 curie Cesium -137 source and a 16 curie Americium- 241:Be source was stuck below 12,000 feet. Operating company was fishing for logging tool string. Schlumberger discussed initial procedure of abandoning sources with DRH. During fishing operations logging tool containing sources was pushed to a depth of 14,854 feet. The fishing operation was successful in retrieving the tool string containing the Americium-241:Be source but they did not get the density tool skid containing the Cesium-137 source back. Licensee stated that tool would be cemented in hole with 200 feet of cement and whip stock deflection device. Plan was later modified to drill into cement plug and set casing 160 feet above the abandoned source prior to re-drilling the well to the side of the abandoned source. Schlumberger took survey readings of the recovered source and tool string and did not observe any readings out of the normal readings. Leak tests were also taken of the Americium-241:Be source, with no evidence of leaking. 30 [-day] written report required from licensee. Licensee must also place a plaque on the well bore signifying that abandoned source is in well bore. |
