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

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.

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 ...
