Mesure de propriétés monophasiques de milieux poreux peu perméables par voie instationnaire

Abstract : Among the multitude of petrophysical data used to describe a geological formation,some of them allow specifically to predict the production capacity, namely: the porosity,the intrinsic permeability and the Klinkenberg coefficient. In the particular case ofgas shales, these three essential properties are extremely difficult to measure precisely,because of the complexicity of these rocks. This thesis is the continuity ofworks led in I2M laboratory-TREFLE department, on the analysis and the improvementof the Pulse Decay method, which is the classical transient method of measurementused in the oil&gas industry to identify one or several of the properties ofinterest. The numerous weaknesses of the Pulse Decay method are here presented,as the strengths of the new method derived from the improvement of the Pulse Decaymethod, namely the Step Decay method, developed in I2M laboratory and patentedin partnership with TOTAL. More exactly, the performances of the Step Decaymethod are here studied numerically as well as experimentally, in homogeneouscondition, as in heterogeneous condition. This manuscript provides also the results ofan analysis dealing with the Pulse Decay method on cuttings, which forms a possiblealternative to the Pulse Decay method on plug but which reliability is highly questioned.
