.../formation column height ratio of 0.3, the flow in the matrix can indeed be approximated by one-dimensional flow. For larger values of the ratio, simulations using the onedimensional flow approach are significantly overestimating the gravity drainage rate (for a fracture spacing/formation column height...

... at the top completion, DWS dramatically accelerated the recovery process; A five-fold increase of the oil production rate was reached without changing the rate at the top completion - by adjusting the drainage rate at the bottom completion. The results also showed a 70-percent increase of oil recovery...

... of the Peclet Number (N Pe ) determines the order of the error if the convective term is neglected. To estimate the upper limit of N Pe we used Equation (4) which indicates that the interface velocity, hence the drainage rate, is proportional to the square root of oil mobility at steam temperature...

... fracture blocks on drainage rate and eventual recovery. Drainage rate and eventual recovery may be increased by a greater overburden pressure, and fewer fractures for a given height of medium. In some cases these factors may also be increased by reducing the cross-sectional area for flow across me...

The main conclusion of this paper is that the combination of gravity and capillarity forces generally provides conditions for a pronounced reinfiltration process in fractured porous...
