The payout marked the latest in a series of board decisions that allowed the oilfield suppliers top executives and founders to rake in tens of millions of dollars as shareholders saw the stock price plummet to pennies.
It can also liberate oil from tight rock units as has been done with the Bakken Shale and Niobrara Shale. The hydraulic fracturing process and the chemicals used with it cause the greatest amount of concern to environmental advocates who watch the natural gas industry.
Rasmus gave an undisclosed amount of money for a new 4,000-square-foot entertainment facility - dubbed the Rasmus Family Club that opened in 2017 at Notre Dame stadium, where its storied football team plays. At same the time, Affleck-Graves served as the universitys chief financial officer and, as a Hi-Crush director, was signing off on deals that put millions of dollars in Rasmus pocket.
Since 2014, the board has approved 640 million in company purchases of three sand mines and other assets in which Rasmus and his two co-founders each held a 12.78 stake, according to regulatory filings. The sales grossed the founders a combined 245.5 million, a windfall that came at the expense of other shareholders.

The crew sets up the rig and starts the drilling operations. First, from the starter hole, the team drills a surface hole down to a pre-set depth, which is somewhere above where they think the oil trap is located. There are five basic steps to drilling the surface hole

Jan 26, 2018nbsp018332What is shale gas and how much is there globally Shale gas is a form of natural gas mostly methane, found underground in shale rock. It is classified as unconventional because it is found in shale, a less permeable rock formation than sandstone, siltstone or limestone in which conventional gas is found, and it is generally distributed over a much larger area.
Estimates of global deposits range from 2.8 to 3.3 trillion barrels 450215109 to 520215109 m3 of recoverable oil shale in place. Heating oil shale to a sufficiently high temperature causes the ...

Four basic steps are involved in the aboveground processing of oil shale mining the ore either through underground or surface mining, crushing the ore to a size that can be handled by the retort, retorting heating the crushed shale to pyrolysis temperatures, and upgrading the oil obtained by pyrolysis of the organic content of the shale.
Hi-Crush has been one of the leading providers of sand for the Texas boom in fracking, a drilling method that involves blasting sand and water into shale rock to release oil.
Oil produced by in situ processes is generally much lighter and is likely to require less upgrading than oil produced in aboveground retorting. Nevertheless, various upgrading steps are required, including hydrotreating, in part using the higher hydrogen content of the wellhead product. In addition, gas produced from in situ retorting is likely to be sourthat is, containing hydrogen sulfide and carbon dioxide, and those impurities too must be removed.
This invention relates to a process for extracting bitumen from oil shale, and more particularly, to a process and apparatus for extracting bitumen using supercritical solvent techniques.
Oil shale deposits are very extensive worldwide, and found in all major continents. Estimated oil shale reserves could provide hundreds or thousands of times more synthetic crude than conventional crude resources. In the United States alone, it is estimated that over seven trillion barrels of oil are contained in oil shale reserves. These reserves are found mainly in the Green River formation of Utah, Colorado and Wyoming, and in the Devonian-Mississippian Eastern Shale Deposits between the Appalachian and Rocky Mountains.
Efforts to utilize this resource fall primarily into two classes Retorting processes and solvent extraction processes. Retorting may be further subdivided into in-situ and surface processes. Both retorting processes and existing solvent extraction processes require the addition of large amounts of heat to convert the kerogen in the oil shale to bitumen. Retorting requires high temperatures, on the order of 950 F., and surface retorting utilizing gaseous heat transfer media require very large processing vessels for efficient production.
An environmental problem associated with retorting processes is a large up to 3 increase in volume of spent shale for disposal compared to the original shale ore. This is due in part to the high temperature vaporization of the shale oil within the shale ore particles being processed. This rapid vaporization process swells the particles and results in a net volume increase. This prohibits easy disposal of the spent shale in the original mine.
The challenge in the processing of oil shale is to limit the production of gas to the amount required to fuel the process, while at the same time, minimizing the production of carbon which represents lost resource. Thus, it is desirable to recover the converted kerogen bitumen without the conversion to secondary lighter products. Upgrading to the desired final products is more efficient in downstream processing.
Separation of shale oil from spent shale without vaporization implies using solvent extraction. Solvent extraction is based on dissolving the converted hydrocarbon products under reaction conditions. Conversion of kerogen results in disintegration of the shale particles. The extent of this disintegration will be a primary consideration in the design of an oil shale process.
Solvent extraction methods heat the shale in the presence of a solvent to temperatures of about 100 F.-1000 F. and may require hydrogenation to achieve the conversion. Solvent processes generally exhibit better yields than the retorting processes, and a number of variations of the solvent process exist. However, the prior art oil shale solvent processes have problems in separating the spent shale particles from the solvent and bitumen. None use supercritical pressure to maintain the solvents in the fluid state at the elevated temperatures.
