Ravigopal Vennelakanti Anshuman Sahu, Ph.D. Umeshwar Dayal, Ph.D. OVERVIEW: Disruptive innovation in an unconventional oil and gas industry such as the shale industry offers a promise to change the world’s economies. Advances in technologies such as horizontal directional drilling and hydraulic fracturing have fueled growth in the industry. However, oil and gas industry operators are facing tou...

Although the oetiological association between soot and cancer of the scrotum was recognized by Percival Pott as early as 1775, the role of mineral oils in the production of skin cancer was not recognized until considerably later. Joseph Bell of the Edinburgh Royal Infirmary reported a case of carcinoma of the scrotum in a Scottish shale oil worker in 1876. Southam and Wilson (1922) pointed out ...

Oil and natural gas from deep shale formations are transforming the United States economy and its energy outlook. Back in 2005, the US Energy Information Administration published projections of United States natural gas supply that stressed the need to develop an import infrastructure (1): by 2025, imports would account for almost one-third of United States consumption. When we compare those fo...

It was back in the early 1980s. My thoracic surgical colleague asked if I could help him with one of his patients who had developed breathing problems after a lobectomy. The man was on a respirator, the consequence (it turned out) of a post-operative attack of asthma. By the time he had recovered, the pathologist reported the resected lobe to have contained not cancer but pneumoconiotic massive...

Oil prices remained relatively low but volatile in the 2015-17 period, largely due to declining and uncertain demand from China. This follows a prolonged decline from around $110 per barrel in June 2014 to below $30 in January 2016, due in large part to increased supply of shale oil in the US, which was spurred by the development of fracking technology. Most dynamic Cournot models focus on supp...

Oil shale is a potential source of oil that will supplement conventional sources for oil as our needs for fossil fuels begin to exceed our supplies. The resource may be mined and processed on the surface or it may be processed in situ. An overview of the potential technologies and environmental issues is presented.

This study considers the flux of radioactivity in flowback fluid from shale gas development in three areas: the Carboniferous, Bowland Shale, UK; the Silurian Shale, Poland; and the Carboniferous Barnett Shale, USA. The radioactive flux from these basins was estimated, given estimates of the number of wells developed or to be developed, the flowback volume per well and the concentration of K (p...

In this study, sedimentary organic matter of oil shale rejects, calschist, shale fine and the so called retorted shale from Irati formation was characterized. EPR was used to analyse the samples regarding loss of signal in g = 2.003 associated to the organic free radical with the calcined samples and washing with hydrogen peroxide. The radical signal was detected in all samples, however, for th...

Nuclear Renewable Oil Shale Systems (NROSS) are a class of large Hybrid Energy Systems in which nuclear reactors provide the primary energy used to produce shale oil from kerogen deposits and also provide flexible, dispatchable electricity to the grid. Kerogen is solid organic matter trapped in sedimentary shale, and the formations of kerogen oil shale in the western United States are the large...
