Synchrotron 4D X‐Ray Computed Tomography of a Porous Limestone: Influence of Porosity on Deformation Mechanisms at Multiple Scales

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract This study investigates the relationship between deformation mechanisms and heterogeneity of porosity of a porous carbonate rock across several scales. The Saint Maximin limestone (SML), characterized by centimeter‐scale alternations of dense and porous zones, serves as a model rock to examine the evolution of deformation modes.

Implications of Fracture Networks in Elastic Response of Heterogeneous Carbonate Reservoirs

Earth and Space Science, Volume 12, Issue 8, August 2025.
Abstract In this research, we explored how various fracture parameters could influence the elastic response of heterogeneous carbonates. Herein, 16 core plugs from a fractured carbonate formation are subjected to a comprehensive analysis including CT‐scanning, optical and electron microscopy, and XRD analysis to identify and characterize open fractures

Study on the mechanism of gas-water two-phase flow in carbonate reservoirs at pore scale

Petroleum
Carbonate gas reservoirs generally contain water, leading to uneven water invasion, explosive water flooding and other prominent phenomena, which is an important factor restricting the efficient development of gas reservoirs.

Bayesian Seismic–Petrophysical Inversion for Rock and Fluid Properties and Pore Aspect Ratio in Carbonate Reservoirs

Geophysical Prospecting, Volume 73, Issue 6, July 2025.
ABSTRACT Seismic characterization of carbonate reservoirs is a challenging task due to the complex structure of carbonate rocks, where the seismic response is affected by multiple factors such as pore volume and shape as well as changes in mineralogy due to dolomitization and silicification.

Investigation on Water Invasion Mode and Remaining Oil Utilization Rules of Fractured-Vuggy Reservoirs: A Case Study of the Intersection Region of S99 Unit in Tahe Oilfield

, 2023
Fractured-vuggy reservoirs are a new target in carbonate oil and gas exploration and development. Because of well-developed reservoir bodies, including fractures and caverns, bottom water invasion can be observed in oilfield development, with low ...

Numerical Investigation of Interaction Mechanism between Hydraulic Fracture and Natural Karst Cave Based on Seepage-Stress-Damage Coupled Model

Energies, 2022
Oil/gas is mainly distributed in caves for fractured-vuggy carbonate reservoirs, it is therefore of significance to effectively connect caves for successful carbonate reservoir development.

Analysis of Flow Behavior for Acid Fracturing Wells in Fractured-Vuggy Carbonate Reservoirs [PDF]

Mathematical Problems in Engineering, 2018
This study develops a mathematical model for transient flow analysis of acid fracturing wells in fractured-vuggy carbonate reservoirs. This model considers a composite system with the inner region containing finite number of artificial fractures and wormholes and the outer region showing a triple-porosity medium. Both analytical and numerical solutions

Sedimentology and reservoir characterisation of Lower Jurassic clastic sedimentary rocks, Salt and Trans Indus Ranges, Pakistan: Evidence from petrography, scanning electron microscopy and petrophysics

The Depositional Record, Volume 11, Issue 2, Page 698-717, April 2025.
In this study, sandstones of the Lower Jurassic Datta Formation (DF‐LJ) in the Salt and Trans‐Indus Ranges are investigated regarding composition, diagenesis, provenance and reservoir properties using petrography, scanning electron microscopy (SEM) and petrophysical analysis.

Modified Starch Gel Foam: Research and Application in Naturally Fractured-Vuggy Carbonate Reservoir

, 2017
Tahe oilfield is one of the most important naturally fractured-vuggy carbonate oil fields in China. The characteristics of this type of reservoirs are greatly complex due to its multiple flow units: matrix, fractures and vugs. Gas flooding is a practical

The Effect of Hydrothermal Alteration and Microcracks on Hydraulic Properties and Poroelastic Deformation: A Case Study of the Blue Mountain Geothermal Field

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Geothermal energy plays a vital role in decarbonizing electricity and heat supply. Effective utilization of geothermal resources hinges on identifying or generating permeable reservoir zones and understanding how effective pressure variations affect fluid circulation and reservoir properties by poroelastic deformation.
