Stimulated reservoir volume (SRV), the highly permeable fracture network created by hydraulic fracturing, is essential for fluid production from low-permeable reservoirs. However, configuration of SRV and its impacting factors are largely unknown. In this work, we adopt stochastic discrete method to mimic natural fractures in subsurface formations conduct a global sensitivity analysis with Sobo...

accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...

The process of storing natural gas in geological formations involves applying pressure to force the into and out porous permeable reservoir. In response extraction/withdrawal storage/injection, reservoir compresses expands as a major consequences fluid pore variations. challenge associated with this type energy systems is learning variations within grid being injected and/or withdrawn. As such,...

To delineate the spatial distribution of high saturation gas hydrate reservoirs in low-angle subduction areas Makran Accretionary Prism, we conducted seismic data interpretation and impedance inversion hydrates Prism comprehensively analyzed characteristics Nankai Trough Japan Shenhu Area South China Sea. The results show that features thick sediments, developed transport systems “two-way suppl...

Rock typing is known as the best way in heterogeneous reservoirs characterization. The rock typing methods confine to various aspects of the rocks such as multi-scale and multi-modal pore types and size, rock texture, diagenetic modifications and integration of static/dynamic data. Integration of static and dynamic behavior of rocks and their sedimentary features are practiced in this study. Po...

The production characteristics of wells in the northwestern Cerro Prieto 111 area changed greatly when the CP-111 power plant went on line in 1986. Fluid extraction in the field more than doubled and reservoir-wide boiling started immediately, greatly increasing the enthalpy of produced fluids. Some well fluids showed a decrease in chloride due to adiabatic steam condensation in the well and se...

The current conceptual picture of steady-state multiphase Darcy flow in porous media is that the fluid phases organize into separate flow pathways with stable interfaces. Here we demonstrate a previously unobserved type of steady-state flow behavior, which we term "dynamic connectivity," using fast pore-scale X-ray imaging. We image the flow of N2 and brine through a permeable sandstone at subs...
