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.

Method for estimating fluid saturation of a rock

Methods and systems for treating a subsurface hydrocarbon formation are described herein. A method for treating a subsurface hydrocarbon formation includes applying electrical current to a one or more heating elements positioned in a first tubular located in an opening in the subsurface hydrocarbon formation; providing fluid through a second tubular positioned in the first tubular in the subsurface hydrocarbon formation such that a portion of the fluid flows between the first tubular and second tubular and along a length of the tubulars; allowing the fluid to flow into a hydrocarbon layer in the subsurface hydrocarbon formation; and allowing heat to transfer from at least one of the heating elements and the fluid to a portion of the hydrocarbon layer in the subsurface hydrocarbon formation.
