This paper aims to analyze the effects of mineralogy on petrophysical properties and
evaluate the performance of eight permeability estimation models in tight oil sandstones …

Water flooding and gas injection are two traditional secondary development methods for
tight oil reservoirs. Water injection has the problem of small injectivity due to low permeable …

Tight oil sandstones have obscured flow characteristics because of their complex pore
structure and ultralow permeability. In this study, representative elementary volume (REV) …

Tight oil sandstones have complex pore structure due to multiple pore types and multiscale
pore size ranging from several nanometers to dozens of microns. In this study, petrophyiscal …

Abstract Knowledge of pore structure and adsorption capacity provides guidance for better
studying the origin, hydrocarbon distribution, and productivity of shale gas reservoir. In this …

Enhanced oil recovery (EOR) potential in unconventional oil reservoirs looks promising but
remains largely elusive because the industry is just beginning to realize that primary …

Rate-controlled porosimetry is a powerful technique for studying the pore structure of porous
media and the physical properties of porous media. This technique involves injecting and …

Integrated characterization methods from micro-scale to macro-scale were applied to
thoroughly study petrophysical properties of the Upper Triassic Xujiahe fractured tight gas …

The optimal selection of fracturing interval for the exploitation of tight oil reservoirs is very
important for formulating a development program. In this study, the reservoir quality and the …
