HYDROPYROLYSIS OF OIL SHALE [PDF]
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
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.

Synthesis and analysis of jet fuel from shale oil and coal syncrudes [PDF]
Thirty-two jet fuel samples of varying properties were produced from shale oil and coal syncrudes, and analyzed to assess their suitability for use. TOSCO II shale oil and H-COAL and COED syncrudes were used as starting materials. The processes used were

Geological settings of the protected Selisoo mire (northeastern Estonia) threatened by oil shale mining [PDF]
The protected Selisoo mire in northeastern Estonia is located above valuable oil shale resources, partly in the permitted mining area. We describe in detail the geomorphology and geological setting of the mire to understand the natural preconditions for ...

On bitumens, oil shales, and oil coals [PDF]
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.
