“…The first component was the fluid and the second component was a passive scalar. This component behaves as a passive component having no velocity and is advected by the background fluid [29,37,42,43]. LBM was used in the interpretation of the monitoring data from the natural gradient tracer test.…”

Fractured Gneiss aquifers present a challenge to hydrogeologists because of their geological complexity. Interpretation methods which can be applied to porous media cannot be applied to fractured Gneiss aquifers because flow and transport occur in fractures, joints, and conduits. In contrast, the rock matrix contribution to groundwater flow is not very important in Gneiss aquifers. Sodium chloride was injected into groundwater flow under steady state condition as tracer to determine transport parameters which are needed for transport modeling. QTRACER2 was used to evaluate the tracer test data. Lattice Boltzmann method was applied to simulate flow and tracer transport through a fracture zone in Gneiss. Experimental tracer data and the numerical solution by lattice Boltzmann method are compared. In general, the results indicate that a 2D Lattice Boltzmann model is able to simulate solute transport in fractured gneiss aquifer at field scale level.

“…To the extent of the authors' knowledge, the first attempt to model field scale reservoir production using a modified LBM was by Shadab Anwar, advised by Mike Sukop, in their model for fluid flow and solute transport in karst aquifers (Anwar, 2008). Although the method for treating the wellbore boundary was not specified in the dissertation, asymmetrical pressure profiles in the near-wellbore region present in their simulations suggest an alternative approach is needed for the formulation of inner boundary conditions.…”

In this paper, for the first time, a comprehensive methodology for the application of a generalized lattice Boltzmann model towards simulation of fluid flow within a hydrocarbon fractured reservoir is presented to validate its use as a reservoir simulation tool. The lattice Boltzmann method simulates fluid flow by defining a system with microscopic flow characteristics. In this method, the fluid consists of fictitious particles (mass fractions). These particles propagate (stream) and collide. The method assumes discretization of the physical system in both space and time. In space, the particles are allowed to move on lattice nodes. Interaction (possible collision) of particles is evaluated at these time steps. The interaction step is designed in such a way that the generalized Navier-Stokes equation is valid for the time-average motion of the particles.The focus of this work is the formulation of precise boundary conditions on the surface of fractures and the wellbore. In addition, the set of dimensionless parameters that govern the evolution of the pressure profile is redefined. Pressure profiles are presented visually throughout this paper to provide the reader insight how such a product would be utilized by the petroleum engineer.Most importantly, the methodology is tested against commercial software and results show excellent agree-ment for both homogenous and heterogenous reservoir cases. This strong agreement provides motivation for the oil and gas community to expand this model towards more complex subsurface conditions.
