This Tech Talk will demonstrate an extension to our LBM fluid flow solver to account for single-phase and two-phase flow.
Large percentage of reservoir has heterogeneous structure e.g. carbonate and shales. The numerical analysis of multi-phase fluid flows using digital rock is a complex and challenging problem especially for rocks exhibiting pores with multiple length scales. Micro-CT imaging focuses on a single scale and there is a tradeoff between enough resolution to capture the most relevant pore types and large enough volume to be statistically representative. Some pore types are left under-resolved in micro-CT images, and ignoring their contribution to flow simulation can lead to large errors, particularly for two-phase flow simulations
This Tech Talk will demonstrate an extension to our LBM fluid flow solver to account for single-phase and two-phase flow in under-resolved porous regions in addition to resolved pores and presented simulation results for absolute permeability, capillary pressure and relative permeability.
