It is well known that most particle technology studies attempting to predict secondary
properties based on primary properties such as size and shape begin with particle …

The poor proppant-carrying capacity of SC-CO 2 fracturing (SCF) negates its potential
advantages for the exploitation of deep unconventional gas reservoirs over traditional water …

Water-soluble polymers, as thickeners, are the vital component of high temperature-resistant
fracturing fluids. With the expansion of oil and gas exploration and development to deep …

We performed mechanical tests on several, mainly European black shales with different
mineralogical composition, porosity and maturity. The uniaxial and triaxial compressive …

Producing natural gas from shale gas reservoir presents a great challenge to petroleum
industry due to its low permeability nature. The process of gas release and production from …

For the past decade, hydraulic fracturing has been an effective way of stimulating low-
permeable reservoirs to increase hydrocarbon productivity. The development of clean and …

The past two decades have seen a tremendous focus by energy companies on the
development of shale gas resources in North America, resulting in an over-supply of natural …

In order to study the mechanism and relief method of coal seam water blocking effect (WBE)
to improve the efficiency of gas drainage, the causes and the influencing factors of the coal …

The economic production of gas and oil from shales requires repeated hydraulic fracturing
operations to stimulate these tight reservoir rocks. Besides simple depletion, the often …

In this study, a gemini zwitterionic viscoelastic surfactant with a sulfonic group, named VES-
S, was synthesized. The surface activity properties of VES-S were found to show an ultra-low …
