Identification of gas reservoirs and determination of their parameters by the combination of radioactive logging methods
The paper proposes a new approach for using of combination of radioactivity logging, which allows determining a set of gas reservoir parameters (nature of saturation, true porosity, gas saturation coefficient) taking into account influence of the pressure and temperature conditions of occurrence. An...
