  • Method for determining the thermal conductivity of an impregnated porous medium
    Patent number: 9494537
    Abstract: This invention relates to methods for determination of thermophysical properties of porous media filled with fluid, gas, or other mineral medium, and can be used, in particular, in the oil and gas industry. When implementing the method, it is necessary to initially determine a composition of a saturated porous medium and thermal conductivity coefficients of its components. A three-dimensional image of a sample of the porous medium is obtained by X-ray scanning. A thermal conductivity coefficient of the medium is determined by solving thermal conductivity problems, based on decomposition of a computational domain followed by composition.
    Type: Grant

  • Method for core thermal conductivity determination
    Patent number: 8873700
    Abstract: A method for core sample effective thermal conductivity provides for scanning a core sample by X-ray micro-computed tomography scanner and transferring a three dimensional scan image to an image analysis computer for processing. Then a layer thickness to be analyzed is set and a layer with maximum thermal resistance is defined within the image. The value of core effective thermal conductivity is defined by the allocated layer.
