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

open access: yesMathematical 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

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Research on the Behavior of Fracture Closure in Ultradeep Fault‐Controlled Carbonate Reservoirs and Its Impact on Productivity

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
The Shunbei fault‐controlled reservoir fracture development has a strong stress sensitivity. With the extraction of oil and gas, the effective stress on fractures and the matrix rock increases, resulting in the gradual closure of the fractures, thus reducing the inflow capacity.

Study on Water Injection Indicator Curve Model in Fractured Vuggy Carbonate Reservoir

open access: yes, 2021
Fractures and cavities are very well developed in fractured vuggy carbonate reservoirs in Tahe Oilfield, showing obvious constant volume or approximate constant volume characteristics, and the development of karst vuggy reservoirs is characterized by ...

Rock‐buffered versus fluid‐buffered geochemistry of structurally controlled, hydrothermal dolomite: Insights from the Sichuan Basin, China

open access: yesSedimentology, Volume 72, Issue 7, Page 2087-2120, December 2025.
ABSTRACT Structurally controlled hydrothermal dolomitization, commonly driven by high‐pressure, high‐temperature fluid–rock reactions, offers insights into the tectonic evolution of sedimentary basins and the geochemical composition of their diagenetic fluids.

Cooling and Exhumation History of the Paris Basin Southeastern Margin Revealed by Δ47 /U–Pb Carbonate Thermochronology

open access: yesTerra Nova, Volume 37, Issue 6, Page 421-430, December 2025.
ABSTRACT This study applies Δ₄₇/U–Pb thermochronology to the Middle Jurassic carbonates exposed in the southeastern margin of the Paris Basin. By integrating clumped isotope analyses and U–Pb dating of diagenetic carbonates, we reconstruct the thermal and exhumation history of the sedimentary succession.

Wellbore Flow Behavior and Natural Flow Cessation Prediction in Ultra‐Deep Wells: A Case Study of Shunbei Oilfield

open access: yesEnergy Science &Engineering, Volume 13, Issue 11, Page 5385-5400, November 2025.
This study develops a framework for predicting flow cessation in ultra‐deep wells, featuring a crude oil property correction model accounting for ultrahigh pressure/temperature effects, a revised liquid holdup model with field‐fitted coefficients, and an integrated pressure drop model coupled with nodal analysis to link reservoir inflow and wellbore ...

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

open access: yes, 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

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

open access: yesJournal 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

open access: yesEarth 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
