Oil sands GHG lifecycle study using operating data finds lower emitting oil sands cases outperform higher emitting conventional crude cases; a call for more sophisticated tools and reporting

Green Car Congress

Well-to-wheel (WTW) greenhouse gas emissions for in situ SAGD and surface mining pathways generated employing GHOST/TIAX/ GHGenius combination and comparison with SAGD, mining and conventional crude oil literature pathways (all results are on a HHV basis). 74% of WTW emissions in our oil sands pathways.

Report finds diluted oil sands bitumen not more corrosive than comparable heavy crude in pipelines

Green Car Congress

Transmitting oil sands production. Generally, bitumen is diluted either with naphtha-based diluents, NGL liquids, ultra light sweet crudes, condensates, and so on with a density of 650 - 750 kg/m 3 to produce dilbit, typically with a 30:70 diluent to bitumen ratio. it won’t flow through the pipeline with modification.

Study finds plausibly high volumes of Canadian oil sands crudes in US refineries in 2025 would lead to modest increases in refinery CO2 emissions

Green Car Congress

An analysis of the US refining sector, based on linear programming (LP) modeling, finds that refining plausibly high volumes of Canadian oil sands crudes in US refineries in 2025 would lead to a modest increase in refinery CO 2 emissions (ranging between 5.4% to 9.3%) from a 2010 baseline, depending upon the supply scenario.

EIA projects world energy use to increase 53% by 2035; oil sands/bitumen and biofuels account for 70% of the increase in unconventional liquid fuels

Green Car Congress

Worldwide energy consumption will grow by 53% between 2008 and 2035 with much of the increase driven by strong economic growth in the developing nations, especially China and India, according to the reference case in the newly released International Energy Outlook 2011 (IEO2011) from the US Energy Information Administration (EIA).

State Department issues Draft Supplemental Environmental Impact Statement on Keystone XL Pipeline: climate change impacts

Green Car Congress

The US Department of State (DOS) has released its Draft Supplemental Environmental Impact Statement (SEIS) in response to TransCanada’s May 2012 application for the Keystone XL pipeline that would run from Canada’s oils sands in Alberta to Nebraska. The pipeline would primarily transport crude oil from the WCSB and Bakken regions.

Chevron leveraging information technology to optimize thermal production of heavy oil with increased recovery and reduced costs

Green Car Congress

Chevron’s focus on optimizing the thermal management of the Kern River field has resulted in a steady drop in the steam:oil ratio (barrels steam water per barrel oil), resulting in improved economics of the field even with slowly declining production. Data: California DOGGR. Click to enlarge. Source: Chevron. Click to enlarge.

State Department releases final environmental impact statement on Keystone XL Pipeline Project; analysis of GHG emissions

Green Car Congress

Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oil sands using different production processes relative to gasoline produced from reference crudes. The proposed Project is not likely to impact the amount of crude oil produced from the oil sands. Click to enlarge.
