When linkage is achieved between the boreholes there is an abrupt pressure drop and a change in gas composition; from a gas high in methane and low in carbon monoxide to one high in carbon monoxide and low in methane. To be successful the method requires that the flow be controlled and ...
Besides using it as a source of boat caulk, the Spaniards failed to capitalise on the oil wealth of coastal California. However, settlers in the 1800’s quickly took advantage of the oil seeps, and oil was mined for use as a lubricant, road pavement, and lamp fuel. These oil miners ha...
Keith Winning (CB&I) described ongoing attempts to close the gap between CAD and GIS and how a Pods based GIS model could be used in the design and build phases of a project. This requires a change in perspective, from Pods as a repository of as-built data to its use across design and...
A national GHG inventory, monitoring and reporting program is in preparation for six GHGs. However, as Nawyaz observed, ‘GHG emissions and climate change are global problems. The ideal solution [would be] a global policy that puts a price on all pollution across all countries and pollution-...
After the change in the flow velocity and the drawdown, the arch collapses and a new one is generated. For the lowest values of bond strength (Г = 5 J/m2), the sand arches have been reformed as well, but they were unstable and quickly collapsed until 0.005 s. It was noticed that ...
The change in surface behaviour is therefore signif- icantly higher than what would be deduced from macroscopic, batch experiments based on bulk composition. There are only two deviations from this behaviour: Ba, where the difference could equally well be an artefact in the simulations from the ...
Other environmental problems aren’t quite so obvious. Lorne Stockman, a senior research analyst with the climate advocacy group Oil Change International, worries that the coming bankruptcies this year “are an environmental nightmare in the making,” with “wells left to rot as bankruptcy proceedings...
He typically changes the oil in the Peterbilt four or five times a year at $159 each change. "That is $759 a year." He said. "I didn't have to get my hands dirty changing the oil at all for a year thanks to AMSOIL and the by-pass filter system." ...
Just-in-time food delivery system dominates. 1-3 days of supply all up and down the food distribution chain. Climate change poses a major challenge to the finely tuned temperature, rainfall, etc. of our highly concentrated food regime. Must restore diversity of natural web, use diverse rotatio...
The production of petroleum from Canada's oil sands is on the rise with much of it destined for U.S. refineries. As the U.S. takes stock of its greenhouse gas emissions, scientists report in the ACS journal Environmental Science & Technology that the cur
