Leak-off and cleanup behavior of fracturing fluids in the presence of mobile hydrocarbons.
(1997)
Leak-off characteristics in the presence of mobile gas or oil saturation are significantly different compared to those observed in the presence of 100% brine saturation. In the case of mobile gas saturation, the spurt loss ...
A fully-coupled two-phase flow and rock deformation model for reservoir rock.
(1997)
In the application of most of the reservoir rock models to real engineering problems, the role of reservoir rock is frequently limited to its storage and delivery capabilities; the interaction of fluid flow with rock ...
Simulation of penny-shaped hydraulic fracturing in porous media.
(1997)
In another major step, this work derives a pseudo-explicit finite difference scheme (PEFD) to compute the nonlinear, coupled problem of modeling the HF propagation. It is fully implicit in the time marching and is thus ...
Influence of stress on the petrophysical properties of flow units in clean and shaly heterogeneous formations.
(1997)
The results show that increasing effective stress reduces the value of reservoir quality index under stress (RQIs) for clean formations. In addition increasing effective stress significantly reduces the value of reservoir ...
A new conceptual approach to shale stability.
(1997)
Based on this broad investigation, the most probable instability mechanism is the creation of cracks with subsequent penetration of the drilling fluid into the fractures. An innovative conceptual model to analyze wellbore ...
