Gas-extraction device () for extracting at least one gas contained in a drilling mud, the device comprising: &#x2014;an enclosure (), &#x2014;an equipment () for supplying the drilling mud to the enclosure (), &#x2014;an equipment () for introducing a carrier gas into the enclosure (), wherein the device comprises a flow regulator () able to regulate the flow rate of a gas flow containing at least carrier gas, and a pressure controller situated downstream of the enclosure () configured for locally setting a pressure lower than the pressure of the enclosure (), wherein the flow, regulator () is interposed between the pressure controller and the enclosure ().

Gas-extraction device and associated analysis assembly and method

A device () for automatically calibrating an analyzer () used for mud gas or fluid logging, comprising:

Device for automatically calibrating an analyzer used for mud gas or fluid logging, associated analysis system and drilling rig

The device comprises an extractor () having an outlet () at which a gas stream is sampled. The gas stream contains at least one hydrocarbon to be analyzed and at least one interfering compound. A transport line (), is connected to the outlet () of the extractor () to transport the gas stream to an analyzer (A) comprising a detector being able to measure at least one of the hydrocarbons to be analyzed contained in this gas stream. The device comprises a chemical reactor () located between the extractor () and the detector. At least a portion of the extracted gases is transported through the chemical reactor () where a selective catalytic reaction of at least one interfering compound is carried out without any substantial reaction of at least one of the hydrocarbons to be analyzed.
