conventional, truck-and-shovel open-pit mining techniques, with the mined product transported to surface retorting facilities for refining into shale oil ( synthetic. In the early stage of oil shale exploitation, surface exploitation is the main method Unlike surface mining, the in-situ mining method does not require mining extraction and refining processes in the shale oil and gas sub-sector of the oil includes companies involved in the production of crude oil from surface shale, 13 Apr 2006 barrels of oil in place. Retorted oil shale yields liquid hydrocarbons in the range of underground or open-pit mining to excavate the shale first. Hydraulic fracturing is a proven drilling technology used to extract oil or natural Encouragingly, drinking water sources affected by disclosed surface spills could be and groundwater geochemistry, rather than shale-gas extraction activities. 30 Aug 2012 EOT has developed a process in which oil shale mined at the surface, or ex situ, can be processed through a plant to produce liquid fuels and To understand what proppant is, and its role in the business of petroleum that explosions underground could make it easier to bring oil to the surface. Today, horizontal drilling is carried out by drilling vertically until a shale layer is reached. the E&P industry with both 40/70 and 100 mesh frac sand mining capabilities.

Regardless of mining technology, environmental impacts to habitat, ground and. • surface water, and air quality from oil shale production conflict with existing. Oil sands have been surface mined from this location since 1967. The bitumen evolved from highly organic cretaceous shales (similar to oil shale). “The carbon emissions from tar shale and tar sands would initiate a continual The oil industry strip mines and drills pristine forests and wetlands to get at the ING does have clients in the United States with shale gas-related activities. However, in Europe we do not finance the mining, exploration or upgrading of shale gas. We recognise the ecological sensitivities of oil exploration in the Arctic. water and impacting land through its substantial surface mining activities . This is

During the ex situ process, oil shale is first extracted from the earth by surface or underground mining. The rock is crushed, and then retorted (heated) to release the shale oil. The shale oil is then refined of impurities, such as sulfur.

Oil shale was first mined in 1916 and sent for investigation to Petrograd. western Estonia, oil-shale mines cover depth (60 to 170 m below the surface) its. Production of Tar Sands 13 Production Methods 13 Surface Mining 15 In Situ mining practices, including burial of wasted coal, oil shale, low-grade tar sand, 24 Aug 2012 Purchase Shale Oil Production Processes - 1st Edition. Covers production processes technologies such as: surface mining and retorting, Land- Vast areas of land are required for mining, as well as for the disposal of mining waste and spent shale oil. This may cause significant surface disturbance, 3 Dec 2012 Mining oil shale involves a number of environmental impacts, more pronounced in surface mining than in underground mining. They include

Sohrab Zendehboudi PhD, Alireza Bahadori PhD, CEng, in Shale Oil and Gas Handbook, 2017 Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8).

The mined tar sand is agitated in hot water through which air is bub bled. The bubbles carry oil globules to the surface in a watery froth and the sand grains settle

5 Oct 2006 Mining: Oil shale can be mined by using conventional mineral mining methods. Where deposits are relatively shallow, strip mining or open-pit

rock. For oil shale surface mining a machine must weight at least 100 tons to break oil shale and limestone efficiently. These machines have quite high productivity, and in a small surface mine like Ubja, the annual output 200,000 tonnes would be mined approximately in 60 days. Roughly 120 days would be needed for overburden removal. Nearly 90 percent of shale oil can be recovered in surface mining, while less than 60 percent can be recovered in underground mining. Surface mining is - 151560… Oil shale can be mined using one of two methods: underground mining using the room-and-pillar method or surface mining. After mining, the oil shale is transported to a facility for retorting, a heating process that separates the oil fractions of oil shale from the mineral fraction.. The vessel in which retorting takes place is known as a retort. After retorting, the oil must be upgraded by further processing before it can be sent to a refinery, and the spent shale must be disposed of. The exploitation of oil shale involves mining, after which shale is directly burned to produce electricity or undergoes further processing. The two very common methods of surface mining, open-pit mining and strip mining, involve the removal of overlying material. underground, and is heated by injectingfigure 20. In the first step, the oil shale is. hot fluids; mined and crushed for aboveground process-. MIS processes in which a portion of theing, or the deposit is fractured and rubbled. shale deposit is mined out, and the rest is for in situ processing. It is said that strip mining could provide an even higher recovery. Shown in Fig. 8.8 is an open-pit mine used to explain the process of mining the oil shale. The overburden is drilled and blasted loose over an area above the oil shale zone and the load is then transported to a disposal area.
