Oral Presentation

Traditional porous media wave theory, such as the Biot theory and BISQ model, typically rely on the idealized assumption of smooth cylindrical pores. However, in actual reservoirs, pores often manifest as structures with non-smooth walls and varying diameters, where pores and throats alternate, making them far more complex. These real-world conditions pose new challenges, especially in...

Oral Presentation

Predicting production of tight/shale oil has been attracting people's discussion. In this paper, a new method for dynamic analysis and predicting production of multi-fractured horizontal tight/shale oil wells is provided.
After horizontal well fracturing, the boundary-dominated flow is occurred in the fracture, transient linear in the pressure sweep area is assumed as a series of...

Oral Presentation

Airports on South Pacific islands are often built on coral sand foundations. The coral sand particles of the foundations are characterized by high porosity, irregular shapes, and particle fragile. The hydro-mechanical coupling responses of the coral sand foundation caused by the cyclic aircraft load are still unknown. This research focuses on the increase in porous pressure and softening of...

645. Interaction Mechanism Between Hydrate Phase Transition and Deformable Sediment Structure under Cold Seep System

Oral Presentation

Cold seeps under seafloor manifests the migration of methane-rich fluid from the sedimentary subsurface to the seabed and into the water column, and even reach the atmosphere. As an important way of methane cycling on the Earth, the cold seeps are often accompanied by the occurrence of methane hydrates, which are hydrocarbons resources with the high hydrogen to carbon ratio. However, the...

752. Micromechanical Coupling of Irregular Particles and Fluid

(MS12) Advances in computational and experimental poromechanics

Oral Presentation

Exploring the complex interplay between granular materials and accompanying fluids is an intricate problem, as their morphological properties add layers of complexity to the interplay of inertial, viscous, frictional, and elastic forces, which can make modeling such systems difficult. Here, we introduce a novel coupled framework designed to study the impact of particle morphology on granular...

85. Adsorption induced Effective Stress in Porous Media

(MS12) Advances in computational and experimental poromechanics

Oral Presentation

Adsorption and capillarity, in the order of high free energy to low, are the two soil–water interaction mechanisms controlling the hydro-mechanical behaviour of soils. Yet most of the poroelasticity theories of soil are based on capillarity only, leading to misrepresentations of hydro-mechanical behaviour in the low free energy regime beyond vaporisation. This inability is reasoned to be...

47. Prediction of CO2 Injectivity into Low-temperature Water Zones below Natural Gas Hydrate Reservoirs for Non-Leaking Storage

Oral Presentation

Abstract

The potential leakage of carbon dioxide (CO2) from traditional underground carbon storage reservoirs has become a growing concern. This study suggests a novel approach — injecting CO2 into subsea water zones situated under natural gas hydrate reservoirs. The objective is to store CO2 within the water zones in hydrate form, thereby minimizing the risk of future CO2 leaks. Assuming a...

400. Evaluation of Relative Diffusivity of Hydrogen-Methane System for Underground Hydrogen Storage in a Depleted Gas Reservoir Using a Novel Pore-Scale Reactive Transport Model

Oral Presentation

The depleted gas reservoir is considered as one of attractive ways for underground hydrogen storage (UHS). However, due to the chemical reaction during UHS, the diffusion coefficient of the H2-CH4 binary system is more difficult to evaluate. The objective of this paper is to establish a novel pore network model merging H2 reactive transport to evaluate the relative diffusivity of the H2-CH4...
