NMR‐Based Quantitative Characterization of Water Imbibition in Deep Shale Rocks Under Different Pressures and Temperatures

Geofluids, Volume 2025, Issue 1, 2025.
Unconventional tight/shale gas reservoirs have gained significant attention in the energy sector. The importance of temperature and pressure in shale imbibition lies in their profound influence on the kinetics, rate, and ultimate amount of water uptake, which directly impacts the efficiency of gas production.

Evaluating the stability and volumetric flowback rate of proppant packs in hydraulic fractures using the lattice Boltzmann-discrete element coupling method

Journal of Rock Mechanics and Geotechnical Engineering
The stability and mobility of proppant packs in hydraulic fractures during hydrocarbon production are numerically investigated by the lattice Boltzmann-discrete element coupling method (LB-DEM). This study starts with a preliminary proppant settling test,

Numerical Investigation of Fracture Compressibility and Uncertainty on Water-Loss and Production Performance in Tight Oil Reservoirs

Energies, 2019
Multi-stage hydraulic fracturing along with horizontal wells are widely used to create complex fracture networks in tight oil reservoirs. Analysis of field flowback data shows that most of the fracturing fluids are contained in a complex fracture network,

An Analytical Formulation for Correcting the Relative Permeability of Gas‐Water Flow in Propped Fractures Considering the Effect of Brinkman Flow

Water Resources Research, Volume 60, Issue 11, November 2024.
Abstract Gas‐water flow in propped fractures can be commonly observed in various practical applications, including hydrocarbon development, geothermal exploitation, contaminant transport, and geological carbon storage. The fluid flow in a propped fracture can be regarded as Darcy type if only the resistance from the propping materials (e.g., cement in ...

The combination of acidizing and hydraulic fracturing for the stimulation of a tight gas reservoir in Minas Gerais

REM: International Engineering Journal
The combination of acidizing and hydraulic fracturing, or proppant-acid fracturing, seems to be a very logical approach to achieve the maximum stimulated volume in tight gas reservoirs, since the acid solution can stimulate the deep microfracture network

Permeability of large‐scale fractures with ununiform proppant distributions in coalbed methane development

Energy Science &Engineering, Volume 12, Issue 7, Page 3157-3170, July 2024.
Overall permeability of fractures with uniform random distribution of proppant. Abstract The coalbed methane (CBM) productivity is directly determined by the fracture permeability during hydraulic fracturing, which is regulated by the distribution of proppants.
