Bitumen production from the Canadian oil sands provides a point of reference that could be used to observe and better manage the land and water impacts of a rapid transition to unconventional fuels, suggests Dr. Sarah Jordaan of the Energy Technology Innovation Policy Research Group, Department of Earth and Planetary Sciences, Harvard University.

Two new lifecycle studies have found that direct greenhouse emissions from producing, transporting and refining oil-sands derived crude, while greater on average than those from conventional crudes, can also overlap the conventional crude range, depending upon a number of factors.

The “wet” part of a DCT means it uses oil to improve lubrication and cooling. A “dry” DCT does not use oil, but is the more fuel efficient of the two types. Note: For our purposes here, a continuously variable transmission (CVT) does not have gears, so is not part of this comparison. The tail end is where things get interesting.

The impact of rising oil prices on North American light tight oil (LTO) production is said to be a “Catch 22”, the title of Joseph Heller’s popular 1961 novel set in WWII. Too many analysts continue to believe drilling and service has the same problem with rising oil prices. by David Yager for Oilprice.com.
