Displacement-imbibition coupling oil production is a critical technique for enhancing oil recovery (EOR) during water injection development in tight/shale reservoirs. However, the role of pore-throat structures in reservoir rocks during displacement-imbibition processes and their impact on microscopic mechanisms and flow dynamics at different pore scales remain unclear. This study integrates...

Well-stimulation techniques are designed to mitigate formation damage phenomena. Matrix acidizing, a standard stimulation method, involves injecting an acidic fluid into the formation near the well to dissolve rock matrix minerals, create dissolution channels, enhance permeability, and restore well flow. Hydrochloric acid (HCl) is the most commonly used acid for this purpose; however, its high...
Pore Water Pressure management within porous media, particularly in tailings dams, is essential for ensuring the structural integrity of mining operations and mitigating environmental risks. This research applies Digital Image Processing (DIP) techniques to determine displacement fields in a laboratory-scale tailings dam model under controlled conditions. The implications of this research...
In this talk, we survey recent advances in finite-volume type discretizations for mechanics and poromechanics. We will in particular discuss three classes of discretizations. 1) Multi-point stress finite volume methods (MPSA). 2) Two-point stress finite volume methods (TPSA). 3) Multi-point stress mixed finite element methods (MSMFE).
Being finite volume methods, the three classes of...
