A numerical well testing method for fractured-vuggy reservoirs based on fast marching method

open access: yesYouqi dizhi yu caishoulu
In fractured-vuggy reservoirs, triple media consisting of fractures, vugs, or pores significantly affects oil and gas flow. However, traditional well testing interpretation methods have been proven to be ineffective in accurately describing the flow ...

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

open access: yesGeophysical 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.

Elastic Exploring Law Analysis of the Deep Vuggy Reservoir

open access: yes, 2011
The deep cave is an important storage space in the fractured-vuggy reservoir in the Tahe oilfield, with large differences in spatial structure and the complex relationship between oil and water features, so far, mainly in elastic energy as the driving ...

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

open access: yesThe 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.

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

open access: yesJournal 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.

Characteristics of Oil-Water Relative Permeability and Influence Mechanism in Fractured-Vuggy Medium [PDF]

open access: yes, 2011
The fracture system of fractured-vuggy reservoir is dominated by orthogonal fracture, and the vug system develops along the fracture. In view of this characteristic, two different kinds of models were made in this paper: the fracture medium model and the

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

open access: yes, 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 ...

Research on Conductivity Mechanism and Saturation Model Development of Fractured‐Vuggy Carbonate Reservoirs

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Carbonate rocks exhibit complex pore structures composed of matrix pores, vugs, and fractures, which result in non‐Archie behavior in resistivity measurements and present significant challenges for reservoir evaluation. The rapid advancement of digital rock physics offers new approaches to address the complexities in saturation assessment of carbonate ...
