New focus on tar sands
By many analyses, we shall soon be approaching 'peak oil' production — the time when annual output begins to stall in the face of ever-increasing demand. Oil companies are therefore increasing efforts to locate new sources and, in the face of the large-scale environmental problems caused by the failure of a deep-drilling operation in the Gulf of Mexico, the successful development of Canada's ta...
متن کاملDoes the Alberta Tar Sands Industry Pollute? The Scientific Evidence
The extent to which pollution from tar sands industrial activities in northeastern Alberta, Canada affects ecosystem and human health is a matter of growing concern that is exacerbated by uncertainty. In this paper we determine whether physical and ecological changes that result from tar sands industrial activities are detectable. We analyze a diverse set of environmental data on water and sedi...
متن کاملThe Viability of Oil Extraction from Trinidad Tar Sands by Radio Frequency Heating: A Simulation Approach
Trinidad has tar sand resources of about 2 billion barrels of oil on land in the Parrylands/Guapo and Brighton areas. With an oil price of over USD 25 per barrel, the commercial extraction of oil from Trinidad tar sands is viable, but it requires a careful study. The relatively small extent of this tar sand (about 10,000 acres and with depths varying from surface to less than 500 feet) and with...
متن کاملNew Approach for Determination of Bitumen and Water Contents in Tar Sands
A new interpretive algorithm has been developed for bitumen spectra analysis in tar sands. This algorithm utilizes Low Field NMR method for measurements. With the use of appropriate basic components spectra database the algorithm extracts information on bitumen contents, immovable and movable water saturations. The basic components spectra database can be built by analysis of spectra for simila...
متن کاملSeparation of Bitumen from Utah Tar Sands by a Hot Water Digestion- Flotation Technique
To facilitate the efficient handling of large volumes ofinformation generated by logging exploration drill cores, acomputer data bank system (GEOBANK) has been developed tostore and retrieve the normally difficult to handle geologicinformation as well as the physical testing data. The data banksystematized the logging of drill core by first developing astandard list of a...
