Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. Accounting for evaporative emissions (e.g., —Parajulee and Wania. Source: Parajulee and Wania.

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.

and are destined to rise significantly with the use of heavy oils, tar sands, and bitumen as combustion sources. The researchers synthesized published data and provided a quantitative summary of the global biogeochemical cycle of vanadium (V), including both human-derived and natural fluxes. —lead author William H.

Methane hydrate—natural gas trapped in an ice-like cage of water molecules—occurs in both terrestrial and marine environments. Post-cruise analyses will determine the in situ concentrations, the physical properties, the lithology, and the thermodynamic state of methane hydrate bearing sand reservoirs.

Oil and gas services company Schlumberger defines artificial lift as any system that adds energy to the fluid column in a wellbore with the objective of initiating and improving production from the well. maglift de-waterers deeper mature wells, and supports retrofit installation through small diameter production tubing.
