Piri Technologies Establishes a New Subsidiary, Digital Pore Solutions

Piri Technologies has established a new subsidiary, Digital Pore Solutions, to provide advanced computational analyses for characterizing porous materials and multiphase flow and transport in them, with applications related to energy and environment. The computational modeling group at Digital Pore Solutions, LLC, currently works on incorporating more complex, but very important physics of multiphase flow processes, such as mass transfer and convection between different phases, into a more comprehensive dynamic flow model. A dynamic modeling approach is applied to better account for the complex dynamics of multiphase flows. In this dynamic flow model, viscous, capillary, and gravity pressure drop all are considered. Wetting-phase corner flow in capillary elements and adjustments of corner interfaces between wetting and non-wetting phases are also consistently modeled. To upscale and simulate the flow processes in core-scale porous media, a heavily parallelized computing scheme is utilized with the help of an in-house high-performance computing cluster consisting of 60 nodes and more than 1,000 computing processors. This dynamic flow model provides a platform to investigate various flow processes in porous media at the core scale using fundamental pore-scale physics. Currently, our in-house code developers have a dynamic code capable of modeling the largest sample sizes of anyone else in the pore network modeling business. Comprehensive modeling is able to predict or verify capillary pressure curves and relative permeability for both drainage and imbibition processes.
