Strippers contribute to independence

摘要

Stripper wells provide a substantial portion of current US supplies of oil and natural gas. These days there is much talk about drilling in the Arctic National Wildlife Refuge and offshore US on the Pacific and Atlantic coasts. According to Dr. David Greene, Oak Ridge National Laboratory, this is driven by the fact that petroleum provides more than 40% of the world's primary energy and nearly all the fuel for the world's transportation system. Even with all of the advanced diagnostic tools available, finding new oil has become harder and more expensive.
