Another Century of Oil? Getting More from Current Reserves (preview) On fourteen dry, flat square miles of California’s Central Valley, more than 8,000 horsehead pumps--as old-fashioned oilmen call them--slowly rise and fall as they suck oil from underground. Glittering pipelines crossing the whole area suggest that the place is not merely a relic of the past. But even to an expert’s eyes, Kern River Oil Field betrays no hint of the technological miracles that have enabled it to survive decades of dire predictions.When Kern River Oil Field was discovered in 1899, analysts thought that only 10 percent of its unusually viscous crude could be recovered. In 1942, after more than four decades of modest production, the field was estimated to still hold 54 million barrels of recoverable oil, a fraction of the 278 million barrels already recovered. “In the next 44 years, it produced not 54 [million barrels] but 736 million barrels, and it had another 970 million barrels remaining,” energy guru Morris Adelman noted in 1995. But even this estimate proved wrong. In November 2007 U.S. oil giant Chevron, by then the field’s operator, announced that cumulative production had reached two billion barrels. Today Kern River still puts out nearly 80,000 barrels per day, and the state of California estimates its remaining reserves to be about 627 million barrels. [More] rss.sciam.com |
Hoisting One for Wind Power: Climbing Crane Expected to Keep Vestas Turbines Spinning [Slide Show] Now that the United Nations climate talks have wrapped up in Copenhagen, nations agreeing to the accord drafted there are now obliged to keep their promises to cut greenhouse gas emissions . Wind power is one of the key sources of renewable energy expected to play an important role in helping to cut emissions and wean society from its dependence on fossil fuels, which means wind-power companies must be prepared to quickly fix mechanical problems that threaten to slow down renewable energy production.

Study: High Arctic's biodiversity down 26 percent since 1970 Mammals, birds and fish living in the High Arctic experienced an average 26 percent drop in their populations between 1970 and 2004 due to the loss of sea ice, according to a new report from The Arctic Species Trend Index, "Tracking Trends in Arctic Wildlife ."The 2010 report, commissioned and coordinated by the Whitehorse, Yukon–based Circumpolar Biodiversity Monitoring Program (CBMP), was presented Wednesday at the State of the Arctic Conference in Miami. It covers 965 populations of 365 species, representing 35 percent of all known vertebrate species found in the Arctic. [More] rss.sciam.com |
Head Spaces “Does ‘accommodate’ have one ‘m’ or two?” asked an editor in our open workspace. Almost before I could say “two,” the boss flew at us from her office. “Why aren’t you working?” she demanded. She seemed mollified by my explanation. She stalked back to her office chair, periodically watching us through the glass window in the wall.None of us focused too well for a while after that. But her whipsaw behavior was only part of the reason. As I now know--and as you will learn from “Cubicle, Sweet Cubicle,” by sociologists S. Alexander Haslam and Craig Knight--the workspace itself already had done most of the productivity damage. We could not put what we wanted atop our desks, lest we ruin the cohesive look. The seating was changed without discussion. The lack of control over our situation interfered with our concentration. It’s not difficult, however, to create better workspaces.
