Optimization of fracturing parameters for tight sandstone gas reservoirs

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Due to the poor physical properties of tight sandstone, the pore throat is small and the connectivity is poor. In the process of development, fracturing construction is often needed. Reasonable fracturing construction parameters are the key and difficult points of fracturing design, and also the key factor to determine the success of fracturing. Aiming

Preferential Paths of Air-water Two-phase Flow in Porous Structures with Special Consideration of Channel Thickness Effects. [PDF]

open access: yes, 2019
Accurate understanding and predicting the flow paths of immiscible two-phase flow in rocky porous structures are of critical importance for the evaluation of oil or gas recovery and prediction of rock slides caused by gas-liquid flow.

Permeability and permeability anisotropy in Crab Orchard sandstone:experimental insights into spatio-temporal effects [PDF]

open access: yes, 2017
Permeability in tight crustal rocks is primarily controlled by the connected porosity, shape and orientation of microcracks, the preferred orientation of cross-bedding, and sedimentary features such as layering. This leads to a significant permeability

Mineral characteristic of rocks and its impact on the reservoir quality of He 8 tight sandstone of Tianhuan area, Ordos Basin, China

open access: yesJournal of Natural Gas Geoscience, 2019
Tight sandstone reservoirs have low porosity, low permeability, and strong heterogeneity; therefore the reservoir quality becomes the main concern in an exploration.

Tomography of atomic number and density of materials using dual-energy imaging and the Alvarez and Macovski attenuation model [PDF]

open access: yes, 2016
Dual-energy computed tomography and the Alvarez and Macovski [Phys. Med. Biol. 21, 733 (1976)] transmitted intensity (AMTI) model were used in this study to estimate the maps of density (ρ) and atomic number (Z) of mineralogical samples.

Event-based contact angle measurements inside porous media using time-resolved micro-computed tomography [PDF]

open access: yes, 2020
Hypothesis: Capillary-dominated multiphase flow in porous materials is strongly affected by the pore walls' wettability. Recent micro-computed tomography (mCT) studies found unexpectedly wide contact angle distributions measured on static fluid ...

Interfacial adsorption characteristics of surfactant‐modified nanoparticles: Equilibrium and dynamic effects of salinity at the oil–water interface

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Surfactant‐modified nanoparticles adsorb at the oil–water interface, enabling interfacial stabilization and microemulsion formation. Abstract This study systematically investigated the interfacial behaviour of silicon dioxide (SiO2) and aluminium oxide (Al2O3) nanoparticles (NPs) functionalized with cationic (CTAB), anionic (SDS), and nonionic (Triton ...
