Hydraulic fracturing performance, affected by multiple factors, was essential to the economic exploitation of oil and gas in heterogeneous unconventional reservoirs. Multifactor analysis can gain insight into response reservoirs turn optimize treatment design. Based on characterizations geological setting a glutenite reservoir, hydraulic fracture (HF) initiation propagation process, as well sti...

Natural fractures are important conduits for fluid-flow and can control the deformational behavior of rock. The accurate evaluation of natural fracture geometry in the subsurface is difficult because of the sampling problems inherent to wellbores and indirect investigation methods such as seismic. Because of these limitations in observational capability, predictive models are needed to provide ...

This letter addresses the reservoir design problem in the context of delay-based reservoir computers for multidimensional input signals, parallel architectures, and real-time multitasking. First, an approximating reservoir model is presented in those frameworks that provides an explicit functional link between the reservoir architecture and its performance in the execution of a specific task. S...

Sand production is a common phenomenon in oil and gas reservoirs, which occurs when reservoir fluids exert sufficient drag force on rocks to erode the matrix. Numerical models for sand have been used understand sanding mechanisms forecast sand-production potential of formations design well completion, optimize production, prevent setbacks future operations. This paper presents mathematical mode...

In this study we evaluate the response of oceanic subsurface systems to thermal stresses caused by the flow of warm fluids through non-insulated well systems crossing hydrate-bearing sediments. Heat transport from warm fluids, originating from deeper reservoirs under production, into the geologic media can cause dissociation of the gas hydrates. The objective of this study is to determine wheth...
