| Title | Louisiana Agreement State Report - Lost Well Logging Tool |
| Event Description | [On the morning of May 29, 2008], a Pulsed Neutron Generator (Source #183619) belonging to Baker Hughes Oilfield Operations, Inc. dba Baker Atlas, containing approximately 900 millicuries of Tritium (H-3) was lost into the waters of the Mississippi River. The events were as follows:
A commercial hotshot carrying two complete Pulsed Neutron Tools was dispatched to the Hilcorp dock in Cocodrie, La., from the Baker Atlas facility in Broussard, La. at approximately 3 A.M. this morning [5/29/08]. The tools arrived at the Hilcorp dock at approximately 5 A.M.. The shipment was verified by the Hilcorp dock dispatcher and loaded onto a Hilcorp contracted Crew Boat. Note: there were no Baker Atlas employees included in the transport of this shipment. The Baker Atlas crew was already at the rig when this equipment was ordered. The shipment arrived at Hilcorp S/L 3090 #7, in the Little Pass field at approximately 7 A.M.. At arrival, the Hilcorp company representative noted that the aluminum tubes containing the Baker atlas downhole tools were not strapped down and were extended over the rail of the boat. The Hilcorp representative alerted the Baker Atlas crew, who conducted an inventory of the equipment and found that one tube containing both the upper section and lower section [containing the 900 milliCurie H-3 source] of a Pulsed Neutron Generator Tool was missing. The Hilcorp representative dispatched the crew boat back to the dock to conduct a visual search of the route and dock, but nothing was found. Due to the weight and density of the equipment, it is most likely that the tube (and tools in it) sank to the bottom of the river. Note: the rig is approximately 20 nautical miles from the dock. The customer (Hilcorp) has accepted financial responsibility for this loss and does not believe that a search for the missing equipment would be cost effective. The State of Louisiana considers this event closed. Louisiana DEQ Event Report ID: LA0800011 THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. 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 Less than Cat 3 event. Note: the value assigned by device type "Category 3" is different than the calculated value "Less than Cat 3 |
