Univ. of Calgary team developing nanocatalysts for underground upgrading of heavy oil and bitumen; possible “next generation” of oil sands production

Green Car Congress

Researchers at the University of Calgary are developing ultra-dispersed (UD) nanocatalysts for the in situ upgrading of heavy oil and bitumen from deep reservoirs. One of the challenges of such an approach is the placement of the catalyst deep into the heavy oil plume by transporting a catalyst suspension through the sand medium.

New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. g CO 2 e/MJ for US conventional crude oil recovery. This range can be compared to ∼4.4

U. Calgary analysis of energy balances and emissions of SAGD oil sands production finds need for improved processes; some operations not thermally efficient or net generators of energy

Green Car Congress

Plot of cumulative steam-to-oil ratio (cSOR) vs. ratio of energy produced in form of chemical energy contained in bitumen if combusted to energy injected in form of steam (75% efficient steam generation). From Gates and Larter (2013). One of the key challenges in producing bitumen and heavy oil is their high, variable viscosity.
