Abstract (en)
[origin: WO2006114512A1] A device (53) comprises an enclosure (63) and means (65, 67) for circulating a drilling mud in the enclosure (63). The inventive device is also provided with means (69) for introducing a gas carrier into the enclosure (63), which comprises a pipe (113) provided with a unit (121) for adjusting the gas carrier flowrate. The device (53) comprises a gas extracting pipe (71) open into the enclosure (63). The gas introducing means (69) comprise a sensor (123) for measuring a pressure at a point located downstream of the adjusting unit (121) and means (117) for controlling the flowrate of the gas carrier injected through said adjusting unit (121) according to the difference between a pressure measured by the sensor (123) and a determined gas extraction pressure.
