Conventional gas is usually found in relatively large permeable rock reservoirs. In a conventional gas deposit, once drilled, the gas can usually be extracted relatively easily via vertical wells. Conventional gas has been extracted in Australia for many decades. ... Shale and tight gas mining processes require vast amounts of water

Another major technology often employed in producing natural gas from shale is horizontal drilling (see graphic on previous page). The shallow section of shale wells are drilled vertically (much like a traditional conventional gas well). Just above the target depth – the place where the shale

Feb 21, 2010 Tech Talk: Conventional Mining of Oil Shale Posted by Heading Out on February 21, 2010 - 11:05am So, there we have all this oil, sitting in these nice thick oil shale beds out West and just waiting to turn some local in Colorado into the next world's richest person

A conventional well simply involves drilling down, perforating, and letting the gas flow. Because it doesn’t involve de-watering or hydraulic fracturing, it’s thought to be safer than CSG or shale — but CSG and shale drilling exist in part because all the sweet conventional drilling spots have been drilled. Take Texas for example

Feb 01, 2013 Highlights We examine the impacts of (un)conventional gas and coal on air, water, and land. A shift from coal to shale gas would benefit public health. Shale gas extraction can affect water safety. We discuss technical solutions to fix the most crucial problems of shale gas extraction. We recommend hybrid regulations

Surface mining and retorting Land use and waste management. Surface mining and in-situ processing requires extensive land use. Mining, processing and waste disposal require land to be withdrawn from traditional uses, and therefore should avoid high density population areas. Oil shale mining reduces the original ecosystem diversity with habitats supporting a variety of plants and animals

Feb 18, 2013 Oil shale can be mined above and underground, crushed and then transported to a retort where it is heated to a high temperature, and the oil collected in a distiller. This results in an oil similar to that pumped up from conventional underground wells, but the process is more complex and therefore, more expensive at the present time

However, full-scale oil shale processing is expected to require 0.7 to 1.2 litres of water for every litre of oil produced, primarily for site remediation, drilling or mining, and upgrading of the synthetic crude. Power generation could be an important additional application for oil shale if traditional methods of steam condensation are used
