The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

open access: yesDeep Underground Science and Engineering, EarlyView.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Entropy‐Stabilized Pd/HEO Bifunctional Catalyst for Selective Aqueous‐Phase Hydrogenolysis of Cellulose to Ethylene Glycol

open access: yesEcoEnergy, EarlyView.
An entropy‐stabilized Pd/HEO catalyst integrates Lewis acid and hydrogenation sites within a robust oxide–metal interface, enabling efficient and selective conversion of cellulose to ethylene glycol (68.3%) in water. ABSTRACT The selective conversion of cellulose into ethylene glycol (EG) under aqueous conditions is an attractive yet challenging route ...
