(MS12) Advances in computational and experimental poromechanics

Oral Presentation

The drilling of geothermal energy, CO$_2$ sequestration, and wastewater injection all involve the pressurized flow of fluids through porous rock, which can cause deformation and fracture of the material. Despite the widespread use of these industrial methods, there is a lack of experimental data on the connection between the pore pressure rise, the deformation, and permeability changes in...

320. Pore-scale Analysis of Carbonate Acidification Based on CT Scan Imaging: An Experimental Investigation

Victoria Farçal Rocha da Costa (Federal University of Pernambuco)

(MS12) Advances in computational and experimental poromechanics

Oral Presentation

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...

506. DETERMINATION OF DISPLACEMENT FIELDS USING DIGITAL IMAGE PROCESSING IN A TAILINGS DAM TEST MODEL UNDER INCREASING PORE WATER PRESSURE

(MS12) Advances in computational and experimental poromechanics

Oral Presentation

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...

657. Finite volume methods for poromechanics

(MS12) Advances in computational and experimental poromechanics

Oral Presentation

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...

699. New insights into unsaturated soil mechanics: analytical derivation of pore-pressure coefficients using a generalized effective stress framework

Angelica Tuttolomondo (EPFL)

(MS12) Advances in computational and experimental poromechanics

Oral Presentation

Geotechnical operations such as slope excavation, earth dam construction, and drawdown scenarios often involve rapid mechanical loading or unloading in unsaturated soils. These dynamic processes typically progress so quickly that they do not allow for pore water and air migration, thereby inducing significant changes in pore water and air pressures. Accurately predicting these pressure changes...
