Summary Fractured-reservoir relative permeability, water breakthrough, and recovery cannot be extrapolated from core samples, but computer simulations allow their quantification through the use of discrete fracture models at an intermediate scale. For this purpose, we represent intersecting naturally stochastically generated fractures in massive or layered porous rock with unstructured hybrid finite-element (FE) grid. We compute two-phase flow implicit FE/finite volume (FV) method (FE/FVM)...
Abstract Realistic simulation of structurally complex reservoirs (SCR) is challenging in at least three ways: (1) geological structures must be represented and discretized accurately on vastly different length scales; (2) extreme ranges discontinuous variations material properties have to associated with the accounted for computations; (3) episodic, highly transient often localized events such as well shut-in resolved adequately within overall production history, necessitating a adaptive...
Abstract Fractured reservoir permeability, water-breakthrough and hydrocarbon recovery cannot be extrapolated from experimental data obtained on cores. Instead computer simulations allow these processes to studied in discrete-fracture models at an intermediate scale. We represent intersecting natural stochastically generated fractures massive or layered porous rocks accurately with novel unstructured hybrid finite-element meshes. This high-resolution discretization allows us compute...

One of the largest problems for tokamak devices such as Kazakhstan Tokamak Material Testing (KTM) is operation scenarios' development and execution. Operation scenarios may be varied often, so a convenient hardware software solution required scenario management Dozens diagnostic control subsystems with numerous configuration settings used in an experiment, it to automate subsystem process coordinate changes related prevent errors. Most at KTM was unified using extra layer, describing...
