Canadian Government: Greenhouse gas emissions from tar sands may double by 2020

by

A newly-released report from the Canadian government reinforces the looming environmental impact of tar sands oil: As producers ramp up their activity, due in large part from a projected increase in demand from U.S. refineries, greenhouse gas emissions from Alberta’s tar sands could double by 2020 compared to 2010 levels.

U.S. shale gas: Less abundance, higher cost

by

Shale gas has become an important and permanent feature of U.S. energy supply. Daily production has increased from less than 1 billion cubic feet of gas per day (bcfd) in 2003, when the first modern horizontal drilling and fracture stimulation was used, to almost 20 bcfd by mid-2011. There are, however, two major concerns at the center of the shale gas revolution. Despite impressive production growth, it is not yet clear that these plays are commercial at current prices because of the high capital costs of land and drilling and completion. Reserves and economics depend on estimated ultimate recoveries based on hyperbolic, or increasingly flattening, decline profiles that predict decades of commercial production. With only a few years of production history in most of these plays, this model has not been shown to be correct, and may be overly optimistic.

When oil and gas are depleted

by

In this year, 2011, we are enjoying a lifestyle beyond the most optimistic dreams of past generations. We are benefitting from the whirlwind of achievements in science and technology during the last hundred years. There has never been a century like the one just passed, and there will never be another like it. Lifestyles will be very different when oil and gas are depleted.

Profits were up at the supermajors again in Q2 as high oil prices offset the rising cost of new production. Shell’s Peter Voser said that high prices were having an effect on demand for oil, especially in Europe – this could be seen reflected in flat UK growth figures and weak numbers even for major German manufacturing companies.
