... In this work, we extend the consideration on the stress-controlled flow rates beyond the transient flow region into the territory of the long-term stabilized (boundary-dominated) flow under stresses. These stresses impact both the matrix permeability and the hydraulic fracture conductivity. Let...

... (ACGS) has been proposed to enhance heat production in this research. The ACGS incorporates a hydraulic fracture, partitioned by a horizontal insulator for vertical zonal isolation of fluid flow in the fracture, into the closed-loop system's fluid circulation. Since working fluid flows through...

... the wellbore. Significantly larger reservoir exposure and reduced drawdown: While the increased connection length is a direct contributor to the reduced drawdown, the laterals also create access to higher reservoir pressures in previously isolated layers. Connections to naturally producing fractures...

The experimental device used for evaluating the self-supported fracture conductivity in this experiment is an unconventional oil and gas multifunctional flow testing and evaluation system, jointly developed by China University of Petroleum (East China) and Beijing Yongruida Technology Co., Ltd...

... The petrophysical properties of intergranular porosity are related to particle size, sorting, and intergranular porosity. Vuggy porosity systems that are interconnected (touching vugs) cannot be directly related to porosity but are related to fracture pore space geometry, large vugs, and collapse...

...Overview of the Decision Criterion for Acid Stimulation Techniques Abstract Most oil and gas wells are stimulated. In unconventional reservoirs, proppant fracturing is the preferred stimulation technique. However, in higher permeability conventional carbonate reservoirs, matrix acidizing...

... For more realistic description on hydromechanical behavior near high permeable fracture regions, it is necessary to capture more detailed fracture geometry with refined grid cells. Local Grid Refinement (LGR) is widely used to refine the grid size of the fracture regions and reduce...

...Introduction Abstract Lost circulation on drilling wells within the fractured limestone reservoir results in a significant loss of time when treating the losses. Furthermore, lost circulation can be detrimental to well productivity due to the damage caused by the influx of lost circulation...

... For reservoirs with smaller hydrocarbon columns, lower mobility, or limited number of layers that can be comingled with a near vertical- well, the EUR/recovery factors are often insufficient to justify a commercial development with vertical fractured wells. This is illustrated in Figure 2...

... these tight rock formations presents a unique challenge. Hydraulic fracturing, also known as fracking, has become a critical technology for unlocking the vast potential of unconventional reservoirs ( Liu et al., 2019 ). The process involves injecting a high-pressure fluid, typically a mixture of water, sand...
