| ENS 42987 | 20 September 2006 06:00:00 | Agreement State | Agreement State Report - Abandoned Source | The state provided the following information via fax: Precision Energy Services abandoned a 2 Ci source of Cs-137 (serial number 06926B) down a hole at a depth of 3064 feet. The tool string got stuck on September 20, 2006. The first attempt to retrieve the stuck tool string succeeded in retrieving the Am/Be neutron source but also caused the tools to break apart. The section of the tool string with the Cs-137 source was stuck at a depth of 3064 feet. Red-dyed cement plug was set with open-ended drill pipe at 3060 feet to 2860 feet. Production casing was run and cemented at 2850 feet, with float shoe, 41 feet of cement filled shoe joint, and float collar. The deflection device was dropped on the float collar and 20 feet of red-dyed cement was dumped on the device on November 1, 2006. An identification plaque will be placed on the well. | ||
| ENS 42302 | 2 December 2005 06:00:00 | Agreement State | Aggreement State - Abandoned Well Logging Source | The following information was received from the State of Louisiana, Department of Environmental Quality, via facsimile: Precision Energy Services abandoned two sources in Well Logging operations. The logging tool was initially stuck on December 2, 2005 and abandoned on December 7, 2005. A 20 Ci source of Americium-241 (Beryllium) and a 2 Ci source of Cs-137 were abandoned at a depth of 6197 Feet. All abandonment procedures were followed. Deflection devises and cement were filled to a depth of 5902 Feet. Louisiana Event Report ID Number: LA 050010. THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy. Although IAEA categorization of this event is typically based on device type, the staff has been made aware of the actual activity of the source, and after calculation determines that it is a Category 2 event. Note: the value assigned by device type "Category 3" is different than the calculated value "Category 2 | ||
| ENS 41903 | 2 August 2005 05:00:00 | Agreement State | Agreement State Report - Stuck Well Logging Source | The State provided the following information via facsimile: On August 2, 2005, Precision Energy Services had a 2 Curie source of Cs-137 and a 20 Curie source of Am/Be 241 get stuck down hole at a depth of 11,300 feet. The well depth is 12,000 feet. Precision Energy Services is trying to retrieve the well logging tool that has the two radioactive sources in it. The well is offshore in Louisiana waters.
