The lattice Boltzmann method (LBM) is a relatively new technique in computational fluid dynamics. Its capability in coping with complicated boundary conditions arouses great interest from oil and gas industry. In this study, the LBM was used for the simulation of fluid in order to analyze the transport properties of a core sample. In addition, a combination of high-performance computing and the LBM provides the feasibility of obtaining high-resolution results. To this end, the OCCA portability library, an unified approach to multi-threading programming, was employed in the provided implementation, which enables the LBM code to utilize several different application programming interfaces (APIs) including open computing language (OpenCL), compute unified device architecture (CUDA), and open multi-processing (OpenMP). As a result, the OCCA accelerated code on a GPU had substantial speedups compared with an unoptimized serial code on CPU and realized the efficiency requirement of industrial production.
