Summary In this paper, we describe a methodology to identify reservoir properties by using numerical techniques that combine finite element methods, streamline approach, and genetic algorithms. As model problem, consider the system of equations governing incompressible miscible displacement in two dimensions (2D) which solution furnishes tracer breakthrough profiles are parametrized as functions be determined. Given population initial parameters, after problem comparison each profile with...
Summary A new triple porosity model for reactive transport of gas in shale reservoirs is developed within the framework a reiterated homogenization procedure. Considering composed three different levels: nanopores kerogen organic matter, micropores between aggregates and impermeable inorganic matter (clay, calcite, quartz), induced fractures along with four separate length scales (nano, micro, meso macro) associated pore-sizes, up-scaling method based on asymptotic expansions formally...
In this paper we develop a new model to describe the hydrodynamics of gas flow in multiporosity shale reservoir including natural and hydraulic fractures. The matrix is envisioned as medium composed four levels porosity associated with nanopores, micropores, fractures five distinct length scales. bridging between at different scales accomplished within framework homogenization procedure. At finest (nano) scale, absorbed intra-kerogen nanopores. upscaling level gives rise storativity organic...
Abstract In this work, the finite element solution of flow miscible and immiscible incompressible fluids is addressed. A block-iterative scheme used to solve resulting equations in time, combined with element-by-element iterative techniques, a dynamic mesh partition algorithm where pressure equation always implicit transport may be treated as or explicit, an adaptive time step control strategy. Numerical experiments on CRAY Y-MP for five-spot patterns analysis problem water injection...
Summary We developed a new three-scale (micro/meso/macro) computational model based on reiterated homogenization procedure to describe coupled flow and geomechanics in carbonate rocks containing complex geological structures at multiple length scales, such as fractures mainly solution-collapse breccias. Within this framework we construct Hierarchical Karst-Fracture Model wherein larger objects are incorporated the mesoscopic explicitly, whereas high density smaller structures, which prevail...

As model problem consider the system of equations governing incompressible miscible displacement in two-dimensions whose solution furnishes tracer breakthrough profiles are parametrized as function be determined.
