Ionic liquid-enhanced solvent extraction for oil sands bitumen shows high recovery rates, less water use and no tailing water

Green Car Congress

Researchers from Tianjin University and the National Engineering Research Centre for Distillation Technology, Tianjin, China, report on the use of an ionic liquid (IL) with low viscosity to enhance bitumen recovery from oil sands by solvent extraction while reducing adverse impacts in the ACS journal Energy & Fuels.

USGS/BOEM study identifies method to differentiate between natural seepage and produced oils in waters off Southern California

Green Car Congress

Resource managers now have a method to determine the source of oil found in the waters off Southern California and differentiate between naturally seeped oils and those produced by offshore oil and gas production.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

The majority (62%) of the plantations were located on the island of Sumatra, and more than two-thirds (69%) of all industrial plantations were developed for oil palm cultivation, with the remainder mostly being Acacia plantations for paper pulp production. —Miettinen et al. Earlier post.).

Engineers propose new waterflood method for significant increase in oil recovery

Green Car Congress

Engineers from the University of Houston and the University of Texas report that waterflooding with a surfactant—thereby altering the wettability of oil reservoir rocks—can increase oil recovery from 62 to 85%. Carbonate rocks tend to be “oil-wet”—i.e.,

RPI researchers show power generation from water flow over graphene-coated surfaces; potential for autonomous microsensors for applications in oil and gas exploration

Green Car Congress

Researchers at Rensselaer Polytechnic Institute (RPI) and Rice University led by RPI Professor Nikhil Koratkar have shown that flowing water with various molarities of hydrochloric acid (HCl) over graphene generates induced voltages an order of magnitude higher as compared to carbon nanotubes.
