... in formation fluid, acid and alkali, leak-off, core damage, and fracture conductivity of the developed SPFF were tested. The test results show that the leak-off volume and core damage level of SPFF were less than that of conventional fracturing fluid, thereby effectively reducing the damage to the reservoir...

... subjected to fracture generation and subsequent production. The fracture generation of the child wells was directly modelled in the reservoir simulator with hydraulic fracture conductivity as an exponential function of pressure. The conductivity-pressure relationship of the newly created hydraulic fractures...

... and stage spacing. The HHF model was used to observe changes in volume, permeability and fracture connectivity in undepleted areas close to the fracture network. These areas reveal possible candidates for refracturing. A refracturing scenario that restores fracture conductivity and increases the drainage...

.... However, these different gases showed different performance in both of lab scale and field pilots conducted in shale reservoirs. In this paper, numerical simulation methods of compositional models have been incorporated with LS-LR-DK (logarithmically spaced, locally refined, and dual permeability) models...

... of fracture closure during shut-in and production periods is modeled by adjusting the fracture volume and fracture conductivity dynamically. Non-Darcy behavior due to high gas velocity in fracture and matrix desorption are considered. The coupled effect of multi-phase flow, gravity and geomechanics...

... (2013). The current objective is to study the impacts of sand pumping designs on PFF fracturing efficiency by conducting numerical modeling. In the first step, discrete element method (DEM) and lattice Boltzmann method (LBM) are employed to simulate proppant particle compression, rearrangement...

... would be in orientations not parallel and perpendicular to σHmax. Natural fractures probably contribute more to the unpropped rather than the propped conductivity because of the challenge of proppant transport around corners. The question remains whether there are any shale plays with a high stress...

..., the efficiency of thermal stimulation is mostly constrained by how much the formation area/volume that can be stimulated in a reasonable period of time. Due to the low heat conductivity of coal, it is not possible to heat up a large drainage area/volume by heating the surface of vertical hydraulic fractures...

Also hydraulic conductivity of induced and natural fractures was measured on core plugs at reservoir conditions to assign conductivity values to primary, secondary and tertiary flow paths...

Filter cakes form on the faces of the fracture during injection causing a major pressure drop between the fracture and the reservoir during...

Microseismic event locations were also imported, relative to the treatment wellbore, measured during the time the fracturing treatments were conducted. Microseismic data was used to determine which grid blocks to include in a stimulated reservoir...

First, we use analytical solutions and show that bilinear flow is short unless matrix permeability is extremely low or natural-fracture spacing...

Although it is often anticipated that the fractures are infinitely conductive, the general belief is that the production increases with the proppant amount injected. This paper presents an approach to assess the optimum proppant amount injected...

... . In addition, the non-Darcy flow is found to impose a significantly impact on the early-stage bilinear/linear flow regime, resulting in an additional pressure drop that is similar to lowering the fracture conductivity. The pressure response can be classified into two categories by a penetrating ratio of 0.5...
