... Abstract This paper presents a study of the relationship between permeability and effective stress in tight petroleum reservoir formations. Specifically, a quantitative method is developed to describe the correlation between permeability and effective stress, a method based on the original...

... acid and propped fractures is always necessary. This paper presents an outline of the propagation mechanism of acid fractures including reaction kinetics and fluid leakoff, and the resulting penetration. Upon closure, the impact of the effective stress upon fracture conductivity is shown using...
