The most common method of extracting shale oil is by surface mining. The in situ combustion process is used for extracting shale oil from far below the surface. The extracted shale oil then undergoes pyrolysis at 842 to 932°F (450 to 500°C) to produce oil shale (synthetic crude oil), shale gas and residue (solid). 16.4 Methods of oil shale utilization. The following are the methods of development of oil shale deposits as a solid fuel. The choice of mining method is determined by the depth of the oil shale seam below the surface. Opencast mining is a cost-effective and productive solution. It poses little or no hazard to miners. But opencast mining is environmentally destructive, leaving an indelible mark on the landscape. Shale oil extraction methods are more flexible than traditional oil well drilling. The initial drilling only accounts for 40% of the total cost. Extracting the oil costs roughly $1 million for each well. That made shale oil extraction profitable when oil reached $100 a barrel.

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  technology of factory drilling platforms, as the key technology of shale oil and gas the proposed economic evaluation and analysis method, and the calculation  14 Jan 2007 The Hom-Tov process uses oil shale as a catalyst to extract combustible The oil shale extraction method is suitable for organic matter from  17 Nov 2008 The Energy Policy Act of 2005 (EPAct) identified oil shale as a While either mining method is well-practiced, the expended shale that remains  10 Feb 2011 Then drillers tapped oil in a shale formation under South Texas called the Eagle Ford. Drilling permits in the region grew 11-fold last year. Now 

10 Feb 2011 Then drillers tapped oil in a shale formation under South Texas called the Eagle Ford. Drilling permits in the region grew 11-fold last year. Now 

These are thick Cenozoic lacustrine (lake-formed) deposits which are relatively easy to mine and process compared to carbonate-rich oil shales (marls)  In this way, we are able to use the oil shale more effectively, reduce the need for mining and the required area for storage. The process uses its own energy. The Marcellus is just one shale layer from which drillers are attempting to extract oil and natural gas. 3. The fracturing of the shale in this part of the drilling process   Current Methods of Extraction. Recently, oil and gas companies have been extracting these resources from unconventional reservoirs, such as shale formations. 9 Aug 2019 The mining method uses 2.5 barrels of fresh water required per barrel of Light tight oil and shale oil are extracted by using horizontal drilling 

17 Nov 2008 The Energy Policy Act of 2005 (EPAct) identified oil shale as a While either mining method is well-practiced, the expended shale that remains 

The USGS assesses potential for undiscovered oil and gas resources in and unconventional (continuous) oil and gas resources (such as shale gas) for more   Shale Oil Production Methods. Above Ground. Retorting. • Mining of ore. • Well known technology. • Large environmental impact. – Popcorn effect. – Large open   In Brazil, oil shale is mined in open pits and is retorted for shale oil, liquefied (2 ) the mineral composition of the original shale and the type of retort process;  17 Dec 2019 Though some of these methods had existed for years, they were Before the surge in shale drilling, U.S. crude production had been steadily  3 Feb 2019 The oil field is now the world's second most productive. to replicate and standardize the most effective drilling and fracking methods worldwide. The shale-drilling frenzy in the Permian has enabled the United States not  Shale oil can be produced from a number of black shale deposits in Kansas. of the U.S. Bureau of Mines, production of oil and oil products from shales in this most generally held is that oil shale is the end product of a process involving the   OIL SHALE VALUE CHAIN: FROM MINING TO END PRODUCTS. 15. Mining permits and volumes . Use of by-products of the energy generation process .

This heating process can be done either above ground or while the oil shale is still in the ground. To do it above ground, the rock just has to be mined and then 

Shale oil extraction is usually performed above ground (ex situ processing) by mining the oil shale and then treating it in processing facilities. Other modern technologies perform the processing underground (on-site or in situ processing) by applying heat and extracting the oil via oil wells. Oil shale must be mined using either underground- or surface-mining methods. After excavation, the oil shale must undergo retorting. This is when the mined rock is exposed to the process of pyrolysis -- applying extreme heat without the presence of oxygen to a substance, and producing a chemical change. The most common method of extracting shale oil is by surface mining. The in situ combustion process is used for extracting shale oil from far below the surface. The extracted shale oil then undergoes pyrolysis at 842 to 932°F (450 to 500°C) to produce oil shale (synthetic crude oil), shale gas and residue (solid). 16.4 Methods of oil shale utilization.

In this way, we are able to use the oil shale more effectively, reduce the need for mining and the required area for storage. The process uses its own energy.

These deposits sometimes form oil shale. Capstones are usually made of shale or salt. The upside During the drilling process, rock is analyzed for signs of oil.
