... that utilizes an Advanced Dual Porosity Dual Permeability (A-DPDK) model with local grid refinement (LGR). A hydraulic fracture's conductivity is strongly dependent on the effective stress on fracture face. During production, increased effective stress could cause proppant embedment, crushing, and fracture...

... reservoirs of Surat basin, eastern Australia, have been fracture stimulated for more than a decade with ever evolving treatment designs. In a recent fracturing campaign, critical design changes led to improvements in well performance and in mitigating issues related to proppant flow back and fines production...

... and single trip multi-zone frac-pack completion systems. Despite some of the successes, the project economics of vertical fractured wells in the lower Wilcox remains challenging due to low recovery factors (8 – 20%) and low EUR/layer. This paper describes an alternative lower completion concept...

... Abstract The shale matrix is a multiscale porous medium featuring nanopores, macropores, and micro-fractures, exhibiting distinct transport mechanisms and phase behaviors. This study challenges the assumptions of local thermodynamic equilibrium within each matrix grid and recognizes...

... Abstract Hydraulic fractures are often assumed to immediately stop growing once pumps are shut off after fracturing treatments. However, fluid momentum and rock properties may allow propagation to continue temporarily post-shut-in. The objective of this study is to determine if and under what...

... for their ability to extract heat from hot, dry rock. However, issues remain in assuring safe drilling and proper fracturing owing to a lack of knowledge of damage factors and fracture sequences, both of which are crucial for regulating crack propagation. Conventional laboratory approaches often fail to capture...

... Abstract The interaction between natural and hydraulic fractures (HFs) results in the formation of complex fracture networks. A great deal of uncertainty exists around the geometry and connectivity of these fracture networks. The two primary objectives of this study are: (1) to show how...

... of underground formations and the lifting of overburden, GPS stores water within hydraulic fractures. This study aims to identify the most efficient GPS design to maximize energy storage in subsurface formations focusing on the hydraulic connection between the wellbore and the fractures. We developed...

.... Conventional reservoir mitigation strategies minimize condensate banking by maintaining flowing bottomhole pressures close to dewpoint pressures. However, using this approach with unconventional reservoirs raises concerns, as primary depletions and hydraulic fractures in long horizontal wells make maintaining...

... Abstract Good inter-well connectivity and high fracture network conductivity are crucial to the success of any enhanced geothermal system. Distributed fiber optic data from a geothermal fluid circulation test provides a direct measure of hydraulic connectivity of the wells through hydraulic...

... Abstract This paper is the progress report for the last two years of a three-year DOE funded project aimed at developing and constructing cost-effective hydraulic fracturing tools. These tools are intended to enable zonal isolation for subsurface heat exchange in Enhanced Geothermal Systems...

... Abstract The Sichuan Basin, China's largest shale gas development region, encompasses the natural fracture-rich Luzhou Block. The high-density non-uniform natural fractures in this area significantly influence the construction quality and efficiency of deep shale gas horizontal wells. Research...

... 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 material (LCM...

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...
