Abstract: The present invention provides a method for estimating the permeability of rock from a digital image of the rock. A three-dimensional image of a rock is obtained and segmented, and an image permeability is determined from the segmented image of the rock. Permeability correction factors are obtained from the segmented image and from a non-wetting liquid capillary pressure curve derived from the segmented image, and the permeability correction parameters are applied to the image permeability to obtain a corrected image permeability of the rock.

Abstract: A system and a process for recovering bitumen from oil sands are provided. The system includes a bitumen solvent comprised of at least 75 mol % dimethyl sulfide that is first contact miscible with bitumen, an oil sands material comprised of bitumen, and a contacting apparatus configured to receive the bitumen solvent and the oil sands material and to contact and mix the bitumen solvent and oil sands material to form a bitumen-containing extract and a bitumen-depleted oil sands material. The process includes the steps of providing the oil sands material; contacting the oil sands material with the solvent comprised of at least 75 mol % dimethyl sulfide to form the bitumen-containing extract and the bitumen-depleted oil sands material; and separating the bitumen-containing extract from the bitumen-depleted oil sands material.

Abstract: The present invention provides a method for estimating fluid saturation of a hydrocarbon-bearing rock from a rock image. The image is segmented to represent either a pore space or solid material in the rock. An image pore volume is estimated from the segmented image, and a corrected pore volume is determined to account for the sub-resolution pore volume missing in the image of the rock. An image-derived wetting fluid saturation of the rock is estimated using a direct flow simulation on the rock image and corrected for the corrected pore volume. A backpropagation-enabled trained model can be used to segment the image. A backpropagation-enabled method can be used to estimate the fluid saturation using an image selected from a series of 2D projection images, 3D reconstructed images and combinations thereof.

Abstract: The present invention provides a method for estimating hydrocarbon saturation of a hydrocarbon-bearing rock from a resistivity log and a rock image. The image is segmented to represent either a pore space or solid material in the rock. An image porosity is estimated from the segmented image, and a corrected porosity is determined to account for the sub-resolution porosity missing in the image of the rock. A corrected cementation exponent of the rock is determined from the image porosity and the corrected porosity and is used to estimate the hydrocarbon saturation. A backpropagation-enabled trained model can be used to segment the image.
