Witryna28 lut 2024 · Spontaneous water imbibition is an important mechanism in water-wet fractured reservoirs. For volume-fractured reservoirs, to evaluate the oil productivity and oil recovery through water counter-current imbibition, we propose an analytical method for optimizing the reservoir volume fracturing scheme. Based on the two-phase fluid … Witrynaimbibition gas-brine relative permeability (relperm) on reservoir core samples, e.g. as recommended by McPhee et al. (2015) it is very difficult to establish uniformly progressing brine saturation. This often leads to poor definition of the shape of the relperm function at lower brine saturations when gas has the highest mobility.

WitrynaImbibition is a kind of diffusion in which water is absorbed by solid colloids, resulting in a massive rise in volume.
