The critical desorption pressure is determined by pumping out an area within a well bore. As the pressure in that area is decreased, formation fluid from the surrounding rock matrix is drawn into the area. As the local pressure is decreased further, gaseous bubbles within the formation fluid will begin to form. The formation fluid is observed, and the formation of the gaseous bubbles is detected. The critical desorption pressure is determined based upon the presence of gas within the formation fluid. The concentration of gas within the formation fluid can then be determined based on the determination of the critical desorption pressure.

L'invention concerne la pression de désorption critique qui est déterminée par pompage d'une zone à l'intérieur d'un puits de forage. A mesure que la pression dans cette zone est diminuée, un fluide de formation à partir de la matrice rocheuse environnante est aspiré dans la zone. A mesure que la pression locale est davantage diminuée, des bulles gazeuses dans le fluide de formation commenceront à se former. Le fluide de formation est observé et la formation des bulles gazeuses est détectée. La pression de désorption critique est déterminée sur la base de la présence de gaz dans le fluide de formation. La concentration en gaz dans le fluide de formation peut ensuite être déterminée sur la base de la détermination de la pression de désorption critique.
