Various models featuring horizontal wells with multiple fractures have been proposed to characterize flow behavior over time in tight and shale gas systems. Currently, only very little is known about the effects of nonideal fracture patterns and coupled primary-secondary fracture interactions on reservoir performance in unconventional gas reservoirs. We developed a 3D Voronoi mesh-maker that pr...

conclusions in middle-aged subjects with psc, we found a high rate of non-vertebral fractures and a moderately decreased bmd in lumbar spine and hip. fragility fractures had an impact on physical and mental aspects of hrqol. results in 32% of patients, bmd measured in the hip or spine was below 1.0 standard deviation. a history of fragility fractures (distal forearm and ribs) was reported in si...

Multiphase flow and transport phenomena within fractures are important because fractures often represent primary flow conduits in otherwise low permeability rock. Flows within the fracture, between the fracture and the adjacent matrix, and through the pore space within the matrix typically happen on different length and time scales. Capturing these scales experimentally is difficult. It is ther...

The current concept for high-level radioactive waste disposal at Yucca Mountain is for the waste to be placed in underground tunnels (or drifts) in the middle of a thick unsaturated zone. Flow modeling and field testing have shown that not all flow encountering a drift will seep into the drift. The underlying reason for the diversion of unsaturated flow around a drift is that capillary forces i...

conclusions although external fixation in open pediatric fractures and severe injuries is recommended, intramedullary nailing is also an effective method with low complications. combining pins and flexible intramedullary nails is effective in developing more stability and is not associated with more complications. background tibial fractures are the third most common pediatric long-bone fractur...

Abstract Fluid flow is strongly affected by fractures in unconventional reservoirs. It essential to deeply understand the characteristics with for improving production and efficiency of reservoir exploitation. The purpose this work develop an accurate numerical model evaluate transient-pressure response well intersecting fractures. meshes generated from Fullbore Formation Micro-Imager (FMI) ima...

This paper studies a model for flow in fractured porous medium with intersecting fractures. The fractures are treated as lower-dimensional manifolds and then physical transmission conditions express the pressure jump continuity of flux across Specific attention is borne to when several intersect. resulting system discretized mixed finite element, well-posedness both continuous discrete problems...
