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.

Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

In a paper published in the ACS journal Environmental Science & Technology , Stanford University assistant professor Adam Brandt reviews a number of recent life cycle assessment (LCA) studies calculating greenhouse gas (GHG) emissions from oil sands extraction, upgrading, and refining pathways—the results of which vary considerably.

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.

ExxonMobil Outlook: 35% growth in energy demand by 2040; hybrids to account for ~50% of new vehicle sales

Green Car Congress

By 2040, hybrids are expected to account for about 35% of the global light-duty vehicle fleet, up from less than 1% in 2010. In 2010 China had only about five light-duty vehicles per 100 people, while India had less than two per 100 people; this compares to about 75 vehicles for every 100 people in the United States.

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.

Stanford, UC Santa Cruz study explores ramifications of demand-driven peak to conventional oil

Green Car Congress

In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
