Title	Agreement State Report - Well Logging Tool Ejected During Well Blow-Out
Event Description	The following information was received from the State of Texas via e-mail: Weatherford personnel were logging a well in Howard County, Texas when a blow out occurred. The logging tool was at 3500 feet when the tool and wireline were ejected from the well bore. The blow out preventer did not stop the tool and wireline from being ejected onto the surface. The crew evacuated the drilling rig due to the hazards associated with the high downhole pressure. Initially it was unknown whether the logging tool was still in the hole. A logging company manager conducted radiation surveys and found the tool, with the sources still in place near the logging truck. The sources were secured in their transport shields and returned to the company office for leak testing. At this point, there is no estimate of exposures to personnel at the well site. Texas Report # I-8726 * * UPDATE ON 04/22/2010 AT 1524 EDT FROM A. TUCKER TO R. ALEXANDER * * * The following update was received from the State of Texas via e-mail: The licensee notified the Agency [Texas Department of State Health Services] that leak test results on the cesium and the americium-beryllium sources were satisfactory. The licensee stated that a visual examination of the sources did not find any physical damage. Notified R4DO (J. Whitten) and FSME EO (C. Einberg).
