In the life of oil production can defined into three steps, primary, secondary, and tertiary. Primary recovery include natural mechanisms such as rock expansion, gas cap, solution gas, secondary that use injection water or to maintenance reservoir pressure, enhanced (tertiary recovery) special materials is chemicals fluids, injection, polymer injection. this research done Arabic gum flooding by...

Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after acidizing. To understand the acidizing effect on reservoir rock, the formation rock is analyzed on different scales. An acidizing laboratory te...

This research was conducted to determine how the incorporation of different poroelastic equations would affect measured rock matrix bulk modulus in laboratory. To do this, three experimental methods were used measure modulus, Ks, seven sandstone specimens taken from Świętokrzyskie mine Poland. Those based on governing poroelasticty theory. The has a substantial impact strength against external ...

optimization of reservoir parameters is an important issue in petroleum exploration and production. the ant colony optimization(aco) is a recent approach to solve discrete and continuous optimization problems. in this paper, the ant colony optimization is usedas an intelligent tool to estimate reservoir rock properties. the methodology is illustrated by using a case study on shear wave velocity...

The bank slope of the Three Gorges Reservoir is affected by seasonal water level fluctuations, which leads to deterioration rock mass, resulting in a series geological disasters such as landslides and mudslides. Therefore, thoroughly understand degradation mechanism mechanical characteristics under wetting–drying cycles, uniaxial compression tests triaxial were used reveal relationship between ...

Accurate prediction and understanding of the disorder microstructures in the porous media contribute to acquiring the macroscopic physical properties such as conductivity, permeability, formation factor, elastic moduli etc. Based on the rock serial sectioning images of Berea sandstone acquired by the core scanning system developed by our research group, the reconstructed rock model is establish...

The studied deposit is located on the territory of Republic Tatarstan (Russia). reservoir formation represented by bituminous sandstone. being developed steam-gravity drainage (SAGD). researchers noted that has variability petrophysical parameters in thickness. correct adjustment lithological model will allow us to assess characteristics its thickness, which can better predict and elastic prope...

determination of porosity, permeability, and pore volume compressibility of reservoir rocks and those variations with effective stress changes are of great interest in petroleum engineering. this paper has studied the influence of pore types of carbonate reservoir rocks on pore volume compressibility as well as klinkenberg permeability and porosity at different stress values. in the current stu...
