HYDROPYROLYSIS OF OIL SHALE [PDF]
JES. Journal of Engineering Sciences, 2006 Oil shale from Ellajjun area southern region of Jordan hydrogenated at different conditions. The impact of temperature on weight loss and product distribution was investigated. The experimental runs were conducted at different temperatures. Hydrogen gas introduced after purging to the retort with nitrogen thus; to avoid oxidization during heating ...

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

On bitumens, oil shales, and oil coals [PDF]
Transactions of the Edinburgh Geological Society, 1873 Mr Taylor stated, that of late years we had gained some knowledge on the general subject of what coals and shales were. We were not now in the position we were in fifteen or twenty years ago, when fourteen scientific witnesses went before a very venerable court and said that a certain substance was Coal, while as many on the other side said it was not.

UFM‐Based Simulation of Competitive Multi‐Fracture Propagation in Horizontal Wells
Energy Science &Engineering, EarlyView.Simulation schematic of Competitive Multi‐Fracture Propagation in Horizontal Wells. ABSTRACT Multi‐stage hydraulic fracturing in horizontal wells is vital for stimulating unconventional reservoirs, yet uneven fracture propagation often restricts the effective communication volume of the reservoir.
