We describe a poreto reservoir-scale investigation of wettability variation and its impact on waterflooding. We use a three-dimensional pore-scale network model of a Berea sandstone to predict relative permeability and capillary pressure hysteresis. We successfully predict experimentally measured relative permeability data for the water-wet case, and demonstrate that the model captures experime...

Abstract Flue gas flooding is one of the important technologies to improve oil recovery and achieve greenhouse storage. In order study multicomponent flue storage capacity enhanced (EOR) performance water-alternating (flue gas–WAG) injection after continuous waterflooding in an reservoir, a long core system was built. The experimental results showed that factor gas–WAG increased by 21.25% could...

Waterflooding reservoir interwell connectivity characterization is the fundamental work in oil development, aiming to inverse vital connecting channels between injectors and producers. In this paper, we endow an artificial neural network (ANN) with strong interpretability through ordinary differential equation (ODE) of material balance equation, proposing a physical knowledge fusion (PKFNN). ad...
