the development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. in petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. in this study, which is a...

The article presents a theoretical and experimental substantiation of the method directional unloading reservoir in fields with low-permeability reservoirs. relevance is due to reduction hydrocarbon resources modern conditions need create new efficient environmentally friendly technologies develop deposits hard-to-recover reserves, primarily results study stress-strain state vicinity well, both...

In the production development stages of volatile oil reservoirs and condensate gas reservoirs, especially in early production, phenomenon high gas–oil ratio often occurs. As a result, prediction results are greatly deviated from actual situation, which seriously affects implementation potential excavation increases operation for reservoirs. Therefore, accurate identification is key to improve e...

We develop a stochastic Gross-Pitaveskii theory suitable for the study of Bose-Einstein condensation in a rotating dilute Bose gas. The theory is used to model the dynamical and equilibrium properties of a rapidly rotating Bose gas quenched through the critical point for condensation, as in the experiment of Haljan et al. #Phys. Rev. Lett. 87, 210403 !2001"$. In contrast to stirring a vortex-fr...

The study of flooding gas condensate reservoirs at different stages depletion (25, 50, 75% the dew point pressure and maximum condensation pressure) with potential hydrocarbon content 100, 300 500 g/m 3 voidage replacement by using injection (50, 100 150%). results showed a positive effect water on increase recovery factor, but decrease in production compared to basic options development drive....

The main challenge facing the oil industry is to reduce development costs while accelerating recovery with maximizing reserves. One of the key enabling technologies in this area is intelligent well completions. Intelligent well technology (IWT) is a relatively new technology that has been adopted by many operators in recent years to improve oil and gas recovery. Intelligent well completions emp...

Traditional methods of coal seam gas drainage rely on the use of reservoir pressure reduction to promote gas desorption from the coal matrix. Studies in coal mining gas drainage operations, particularly in coal seams that are deeply undersaturated and have low permeability, found the rate of reservoir pressure reduction was prohibitively slow. In such conditions, lengthy production delays have ...

Recovery of both latent heat and condensate from boiler flue gas is significant for improving boiler efficiency and water conservation. The condensation experiments are carried out to investigate the simultaneous heat and mass transfer across the nanoporous ceramic membranes (NPCMs) which are treated to be hydrophilic and hydrophobic surfaces using the semicontinuous supercritical reactions. Th...
