..., and isolated fracture networks that are extracted from a field-scale fractured carbonate reservoir model. Discrete fracture-matrix (DFM) models were constructed using an unstructured grid with refinement of the matrix rock near fractures. High-resolution simulations of spontaneous imbibition, gravity drainage...

... Abstract In this paper we describe how we have used finely gridded single porosity reference models to simulate the behavior of gravity drainage in fractured secondary gas caps/gas invaded zones with and without block to block reinfiltration. These models were used as reference solutions...

... Abstract We develop a physically-motivated approach to modeling displacement processes in fractured reservoirs. To find matrix/fracture transfer functions in a dual porosity model we use analytical expressions for the average recovery as a function of time for gas gravity drainage and counter...

... index and entry capillary pressure on oil recovery by gravity drainage were investigated at both core scale and reservoir scale. The technique may be especially suitable for reservoirs in which it is difficult to measure relative permeability curves. Such reservoirs include gas-condensate reservoirs...

.... It is also demonstrated, that when a fractured reservoir is subject to a relatively large rate of pressure drop and/or it composed of relatively large blocks, the pseudo steady-state pressure concept gives large errors as compared with transient fromulation. In addition, when gravity drainage and imbibitum...
