Coupled Geomechanics and Flow Modeling of Fractured Reservoirs considering Matrix Permeability Anisotropy

Geofluids, 2022
The effect of geomechanics is crucial in the modeling of fractured reservoirs since fractures can be more stress-sensitive than the rock matrix. In fractured reservoirs, the microscale fractures are often homogenized into the matrix continuum leading to ...

Fracture Detection and Numerical Modeling for Fractured Reservoirs

Energies, 2019
The subsurface fractures could impact the fluid mechanisms dramatically, which makes the modeling of the hydraulic and natural fractures an essential step for fractured reservoirs simulations. However, because of the complexities of fracture patterns and

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

Energies, 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 ...

Forest Reorganization Sustains Carbon Sequestration Under Climate Change

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract Forests currently mitigate anthropogenic climate change by sequestering substantial amounts of carbon, but future carbon dynamics are expected to vary across the temperate forest biome. Previously cold‐limited ecosystems with low disturbance activity could increase their carbon uptake, while water‐limited ecosystems with high disturbance ...

From Empirical Models to Physics‐Informed Neural Networks: The Evolution of Oil Production Forecasting

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Production forecasting for oil and gas wells is a decisive element of field‐development planning because it directly guides recovery strategy design, production optimisation and risk management. Conventional methods, including empirical decline‐curve analysis (DCA) and full‐physics numerical simulation, are limited either by their inability to capture ...

Disentangling Compound Effects of Changing Disturbance and Regeneration Across Temperate Forest Landscapes

Global Ecology and Biogeography, Volume 34, Issue 10, October 2025.
ABSTRACT Aim Global change alters many ecological processes simultaneously. Yet, the interactive and compound effects of these changes remain difficult to quantify. Here, we addressed the question of how changes in disturbance and regeneration processes interactively alter temperate forest landscapes across three continents.

Numerical Study of Elasto-Plastic Hydraulic Fracture Propagation in Deep Reservoirs Using a Hybrid EDFM–XFEM Method

Energies, 2021
Rock yielding may well take place during hydraulic fracturing in deep reservoirs. The prevailing models based on the linear elastic fracture mechanics (LEFM) are incapable of describing the evolution process of hydraulic fractures accurately.

Numerical Simulation of Deep Coalbed Methane Development Based on Embedded Discrete Fracture Model: A Triple Medium Flow Approach

Energy Science &Engineering, Volume 13, Issue 6, Page 3045-3062, June 2025.
ABSTRACT China is rich in coalbed methane resources, especially with significant potential for deep coalbed methane development. As shallow coalbed methane resources gradually deplete, the development of deep coalbed methane has become a research focus.

Dual Porosity Simulation of Gravity Drainage Mechanism Induced by Geological Acid Gas Storage in Naturally Fractured Reservoirs

Energy Science &Engineering, Volume 13, Issue 6, Page 3151-3170, June 2025.
ABSTRACT Acid gases, containing CO2 and H2S, are by‐products of gas sweetening. Geological sequestration of these gases in naturally fractured reservoirs (NFRs) is a practical method to reduce greenhouse gas emission. An industrially accepted approach to simulate fluid flow in NFRs is the dual‐porosity method; however, this method needs multiple ...

Selecting the number of factors in multi‐variate time series

Journal of Time Series Analysis, Volume 46, Issue 1, Page 113-136, January 2025.
How many factors are there? It is a critical question that researchers and practitioners deal with when estimating factor models. We proposed a new eigenvalue ratio criterion for the number of factors in static approximate factor models. It considers a pooled squared correlation matrix which is defined as a weighted combination of the main observed ...
