Tight oil reservoirs have been a concerned of the industry due to their substantial influence on production. Due poor permeability, numerous problems are encountered while producing from tight reservoirs. Petrophysical and geomechanical rock properties essential for understanding assessing fracability reservoirs, especially enhance permeability. In this study, Saadi B reservoir in Halfaya Iraqi...

Fracture characteristics—such as orientation, type, fluid storage capability, and permeability—are complex yet essential information for understanding fractured reservoirs. Fractures are often perceived as permeable pathways, although many fractures partially or completely inhibit permeability within a reservoir. For example, opening-mode fractures (joints) may be partially or entirely sealed h...

The microscopic and geomechanical properties of igneous building stones include the level of alteration, presence of micro cracks, peak strength, porosity, proportion of detrimental minerals, etc. Porosity is reportedly of a devastating impact on the peak strength of igneous rocks. The quartz diorite rock samples in this study were selected from five quarries in Natanz, Iran and subject to micr...

This study addresses the problem of geological structure tightness for purposes enhanced oil recovery with CO2 sequestration. For first time in history Polish survey advanced methods, practical assumptions, and quantitative results detailed simulations were applied to a domestic reservoir as potential candidate combined sequestration project. An analysis capacity its was performed using numeric...

A significant portion of the world's oil reserves is contained in carbonates reservoirs. Because complex hydro-thermo-geomechanical-geochemical processes uptake from these reservoirs difficult. In recent decades, many efforts have been made to model fractured rocks. But on stochastic nature there has done only a few studies. Geochemical models deal with chemical reactions that take place into f...
