Deviation from Darcy Law in Porous Media Due to Reverse Osmosis: Pore-Scale Approach

Shale and tight hydrocarbons are vital to global energy dynamics. The fluid flow in sub-micron pores of oil reservoirs varies from bulk flow. Darcy law is widely accepted model creeping petroleum reservoirs. However, traditional reservoir modeling approaches fail account for the mechanisms that govern accuracy simulators has been improved by incorporating influence effects. there still factors affect mobility need investigation. a chemical potential gradient on was modeled solving transport diluted species equations. findings indicate when acts opposite direction hydraulic pressure (reverse osmosis), exists limiting threshold below which non-linear pattern deviating equation observed. Furthermore, simulation based pore parameters shows effect added, resultant flux 8–49% less. Hence, including will improve dynamics velocity.
