During drilling operations a radioactive source is often used to log reservoir properties. Incidents have occurred where the radioactive source has been damaged by the drill bit resulting in contamination of the drilling mud and the mud tank leading to potential radiation exposure of workers. Previously, drilling specialists have been unaware of this occurrence! To ensure protection of crew and equipment when using a radioactive source Tracerco has developed the TRACERCO™ Mud Monitor. At present this is used by all major drilling companies to ensure safe working conditions are maintained. The TRACERCO™ Mud Monitor is intrinsically safe (has been tested and certified for use in potentially explosive atmospheres, zones 0, 1 and 2). The instrument is easily clamped to the outside of the mud circulation system via the powerful magnet provided. A sensitive detector links with the directional drilling control system. The instrument continuously monitors background radiation levels. If an increase in radiation is detected the system gives a clear signal to the crew of downhole radioactive source leakage.
