Development and Application of a Method for Evaluating Hydrogen Permeability and Porosity of Salt Rocks

SPE Journal, Год журнала: 2025, Номер unknown, С. 1 - 19

Опубликована: Май 1, 2025

Summary The pressure pulse decay (PPD) method is widely used for measuring permeability in tight porous media. However, it can overestimate the of salt rocks to hydrogen due gas leakage at rock-sleeve interface, caused by hydrogen’s high diffusivity. In addition this, time-consuming, particularly materials such as rocks, and error measurements be 60%, making less reliable accurate assessments. We present a modified experimental setup analytical approach fast more determination porosity with hydrogen. Our results demonstrate that this configuration significantly improves accuracy least 10 times reduces duration experiments 4 compared conventional PPD method. validated our methodology through on rock samples sourced from Lotsberg Formation (LSF) Fort Saskatchewan, Alberta, Canada.

Pore-Scale Gas–Water Two-Phase Flow Mechanisms for Underground Hydrogen Storage: A Mini Review of Theory, Experiment, and Simulation

Applied Sciences, Год журнала: 2025, Номер 15(10), С. 5657 - 5657

Опубликована: Май 19, 2025

In recent years, underground hydrogen storage (UHS) has become a hot topic in the field of deep energy storage. Green hydrogen, produced using surplus electricity during peak production, can be injected and stored reservoirs extracted periods high demand. A profound understanding mechanisms gas–water two-phase flow at pore scale is great significance for evaluating sealing integrity UHS optimizing injection, as well space. The structure rocks, space channels fluids, significant impact on fluid processes. This paper systematically summarizes methods characterizing micro-pore reservoir rocks. applicability different techniques was evaluated compared. detailed comparative analysis made advantages disadvantages various numerical simulation tracking interfaces, along with an assessment their suitability. Subsequently, microscopic visualization seepage experimental techniques, including microfluidics, NMR-based, CT scanning-based methods, were reviewed discussed terms dynamic complex transport behaviors. Due to resolution, non-contact, non-destructive, scalable situ high-temperature high-pressure conditions, technology received increasing attention. research presented this provide theoretical guidance further characterization rocks scale.

Clarifying the distribution of temperature and pressure in wellbore cavern during hydrogen injection extraction is crucial for quantitatively assessing stability integrity. This paper establishes an integrated flow heat transfer model withdrawal, analyzing variations both cavern. The parameters natural gas within chamber were compared. specific conclusions are as follows.

As from cavity increases, 5 to 15 m, fluctuation rock diminishes progressively, with effect storage extending at least m. (3) influence thermal conductivity processes also better conductivity, deeper effects penetrate layers, capacity having most significant impact.
