(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

Pore fluids are generally classified into movable fluid and irreducible fluid by one or two NMR T2 cut-offs (T2C). Fluid movability in shale may not be accurately characterized by pore size-based classification methods solely because of the complex pore structure and heterogeneity in pore size. In this study, we propose a nine-grid dual T2C model to characterize critical boundary of fluid and...

237. Study on the distribution characteristics of in-situ stress of Chang 7 reservoir in Ordos Basin

(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

In the Ordos Basin, the Chang 7 shale oil reservoir in northern Shaanxi is superimposed with multiple lithologies in the longitudinal direction. There are differences in the interlayer stress of the thin sand-shale-shale interbeds. The internal stresses in small layers are changeable, resulting in high hydraulic fractures and short extension distances. The effective reconstruction volume did...

260. Multimodal geo-dynamic flow characterization in heterogeneous carbonate reservoir: An integrated approach linking static and dynamic behavior

Mr Jiaheng Chen (Research Institute of Petroleum Exploration & Development, Beijing, China)

(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

Towards bioclastic limestone reservoirs, deposition and diagenesis are often inherently complicated, resulting in extremely strong reservoir heterogeneity, which significantly affect the flow mode and field development by waterflooding. A lot efforts have been put for the study of heterogeneity from the aspect of geology and reservoir separately. Geologists usually struggled on the impact of...

298. A probabilstic approach dedicated to the prediction of the reactive mass transport in porous media

Dr Thomas SAYET (Laboratory of mechanics Gabriel Lamé)

(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

It is known that the degradation refractory processes are mainly related to high temperatures and aggressive working environments. In industrial plants, refractories are in contact with complex chemical components such as slags, fumes, ashes, etc. An optimal design of the refractories rests on a multiphysics model which accounts for the significant physics that take place in the real process....

565. The yield surface of reservoir chalk from the North Sea: influence of age, mineralogy and water saturation.

Frédéric Amour

(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

The exploitation of chalk reservoirs in the context of hydrocarbon production and CO2 and thermal storage causes in situ changes in stress and saturating fluid, which in turn entail rock compaction, seafloor subsidence, wellbore instability and fault reactivation that can ultimately jeopardise the economic viability of a field [1,2]. The efficiency of new technology such as radial jet drilling...

458. Study on Microscopic Imbibition process in Variable Diameter Capillary Tubes

Dr Lihua Shi (China University of Petroleum (Beijing))

(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

Spontaneous imbibition plays an important role in water injection development of tight reservoirs. At present, few research focused on micro-imbibition law considering capillary diameter change in liquid-liquid system. In this study, based on Poiseuille's law and imbibition theory, the theoretical formula of spontaneous imbibition in variable diameter capillary under liquid-liquid system was...

464. Experimental Research of Spontaneous Water Imbibition in Oil-Saturated Reservoirs with Ultra-low Permeability

Prof. Hailong Dang (China University of Petroleum, Beijing)

(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

Spontaneous water imbibition (SWI) in porous media is of great importance in many industries.
It is useful to predict the oil production in the fractured reservoirs developed by water flooding
or associated with aquifers. The objective of this study is to investigate the combined effects
of interfacial tension (IFT), salinity, and wettability on spontaneous Imbibition of water in
ultra-low...

537. A macro-scale elasto-thermo-viscoplastic constitutive model for ‎saturated frozen soils

Mr Dana Amini (Research Assistant, Department of Civil Engineering, University of Manitoba, Winnipeg, Manitoba, Canada)

01/06/2022, 14:35

(MS12) Advances in modeling and simulation of poromechanics

Oral Presentation

Slow-rate time-dependent behavior (i.e., creep) of frozen soils is experimentally ‎observed in the literature. From ‎a ‎poromechanical point of view, frozen soil is a medium composed of a ‎deformable solid skeleton and a porous ‎‎space filled with unfrozen water and ice. In addition to pore ice, ice-rich permafrost can also contain thin ice lenses. ‎‎The rheological properties of saturated...
