... Abstract In fractured buried reservoirs, the fracturing network has a significant impact on fluid circulation and productivity. In this work, we present the results of the analysis of outcrop fracture networks in the Upper Middle Eocene limestone hydrocarbons reservoir, located in Central...

... Abstract The fracture initiation pressure of conventional hydraulic fracturing is the highest, the fractures produced are limited in scale and single in fracture shape. The fracture initiation pressure of supercritical CO 2 fracturing in shale is about 11.58% lower than that of hydraulic...

... Abstract There is no more challenging task for today oil and gas production companies than simulating the production behavior of naturally fractured reservoir fields. These reservoirs are highly prosperous at their early stage of production, only to decline afterward. Previous behavior has...

... Abstract The use of numerical methods for the design of projects in rock masses is increasingly predominant with the increase in digital computing capacities. When the density of fractures is high, it is advantageous to adopt a homogenization approach. However, several difficulties related...

... ABSTRACT: This work presents numerical simulations of the excavation-induced fractures around galleries in Andra Underground Research Laboratory at Meuse/Haute-Marne department in France. An instrumented gallery with geological/geophysical surveys describing the surrounding fractures network...

... events that occurred in the vicinity of the de-stress cuts and long hole stopes. The results of the study have indicated that the first 1m of the yielding pillar towards the core of the pillar was extensively fractured.Moderate fracturing occurred between1.5 m to 2m within the yielding pillar and minor...

... stress in the tangential direction. Where this tensile stress is greater than the tensile strength of the rock, radial stress fractures develop. As the stress wave propagates outwards through the rock, it is followed by high-pressure gas associated with the reacting explosive. The gas expands...
