Three‐dimensional simulation of the acidizing process under different influencing factors in fractured carbonate reservoirs

open access: yesEnergy Science & Engineering, 2023
Matrix acidizing is widely used to enhance oil/gas production in the exploitation of carbonate reservoirs. In this work, a three‐dimensional (3D) hydro‐chemical‐thermal (H‐C‐T)‐coupled model was presented to improve the understanding of the acidizing ...

Effects of fracture aperture and roughness on hydraulic and mechanical properties of rocks : implication of seismic characterization of fractured reservoirs [PDF]

open access: yes, 2005
Roughness and aperture are two important characteristic parameters controlling fluid flow in natural joints and fractures. It has been demonstrated by many authors that knowledge of roughness does not directly lead to that of aperture, and aperture ...

Numerical study failure characteristics of natural fracture under induced stress

open access: yesEnergy Reports, 2023
Hydraulic fracturing is an effective method for developing oil and gas in unconventional reservoirs. The openings of natural fractures directly affect the complexity of the fracture body.

A new approach to upscaling fracture network models while preserving geostatistical and geomechanical characteristics [PDF]

open access: yes, 2015
A new approach to upscaling two-dimensional fracture network models is proposed for preserving geostatistical and geomechanical characteristics of a smaller-scale “source” fracture pattern.

Fractal model and Lattice Boltzmann Method for Characterization of Non-Darcy Flow in Rough Fractures. [PDF]

open access: yes, 2017
The irregular morphology of single rock fracture significantly influences subsurface fluid flow and gives rise to a complex and unsteady flow state that typically cannot be appropriately described using simple laws.

UNDERSTANDING NATURALLY FRACTURED RESERVOIRS

open access: yesScientific Contributions Oil and Gas, 2022
Naturally fractured reservoir differs from clastic reservoirs in the sense that the concepts of porous media which were usually applied for clastic reservoir analysis must be modified. This means that handling naturally fractured reservoir is also different compared to handling clastic reservoir.

Water Intrusion Characterization in Naturally Fractured Gas Reservoir Based on Spatial DFN Connectivity Analysis

open access: yesEnergies, 2020
In this study, the non-intrusive embedded discrete fracture model (EDFM) in combination with the Oda method are employed to characterize natural fracture networks fast and accurately, by identifying the dominant water flow paths through spatial ...
