Title: METHOD FOR DETERMINING THE MECHANICAL PROPERTIES OF RESERVOIR ROCK
Abstract:
At least one sample of reservoir rock is selected and the density, porosity, and composition of the rock in the selected sample is determined. On the basis of the values obtained, a petrophysical model of the reservoir rock is created. The thermal conductivity of the sample is measured. The thermal conductivity of the rock sample is calculated using the petrophysical reservoir model that was created. The measured and the calculated thermal conductivities of the rock sample are compared, and if the measured and the calculated thermal conductivity values coincide, the mechanical properties of the rock are determined using the petrophysical reservoir model that was created. If the measured and the calculated thermal conductivity values diverge, the petrophysical reservoir model that was created is adapted at least once by changing the model parameters. The adapted petrophysical model is used to calculate the thermal conductivity of the rock sample, and the measured and the calculated thermal conductivities are compared until the measured and the calculated thermal conductivity values coincide. When the measured and the calculated thermal conductivity values coincide, the mechanical properties of the rock are determined using the adapted petrophysical reservoir model.
