Multi‐porous extension of anisotropic poroelasticity: Consolidation and related coefficients

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 48, Issue 8, Page 2179-2206, 10 June 2024.
Abstract We propose the generalization of the anisotropic poroelasticity theory. At a large scale, a medium is viewed as quasi‐static, which is the original assumption of Biot. At a smaller scale, we distinguish different sets of pores or fractures that are characterized by various fluid pressures, which is the original poroelastic extension of ...

Tectonically induced travertine deposition in the Middle Miocene Levač intramountain basin (Central Serbia)

Sedimentology, Volume 71, Issue 4, Page 1214-1244, June 2024.
ABSTRACT Travertines are terrestrial carbonates that are commonly associated with fault activity in extensional and transtensional basins. The faults serve as conduits for the rising and mixing of carbonate‐enriched fluids with thermal and meteoric CO2 inputs promoting travertine precipitation at the surface.

Models for naturally fractured, carbonate reservoir simulations [PDF]

, 1998
This report outlines the need for new tools for the simulation of fractured carbonate reservoirs. Several problems are identified that call for the development of new reservoir simulation physical models and numerical techniques. These include: karst and

Pressure transient test analysis of vuggy naturally fractured carbonate reservoir: field case study [PDF]

, 2009
Well pressure transient analysis is widely used in reservoir management to obtain reservoir information needed for reservoir simulation, damage identification, well optimization and stimulation evaluation. The main objective of this project is to analyze,

Adaptability of joint water plugging of s-MPG and MSRG in fractured-vuggy reservoirs in Tahe Oilfield

Youqi dizhi yu caishoulu
The proven reserves of fractured-vuggy reservoirs in Tahe Oilfield are large， and the geological conditions featuring high temperature and high salt are more obvious than the sandstone reservoirs in the eastern area.

Production optimization for water flooding in fractured-vuggy carbonate reservoir - From laboratory physical model to reservoir operation

, 2020
Conventional physical model experiments of carbonate reservoirs are limited to the investigation of production patterns and mechanisms for a single well or a well group, and cannot effectively optimize the oil production at the reservoir scale.

Fracture and vug interaction behavior considering acid etching effect

Youqi dizhi yu caishoulu
Fractured-vuggy carbonate reservoirs are characterized by low porosity， low permeability， and strong heterogeneity. Acid fracturing is the primary technical means to increase the production of this kind of reservoir， and the key to fracturing ...

A Unified Theory for Upscaling Fractured, Vuggy Reservoir Models ��� The Development of Novel Transfer Functions [PDF]

, 2016
More than half of the world s oil and gas reserves are found in carbonate reservoirs. Most carbonates are fractured, vuggy reservoirs which can be defined as reservoirs that contain matrix, fractures and vugs. Vugs in such reservoirs can be isolated or

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

, 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
