Scientists Weigh Use of Bacteria for Cleaner Fossil Fuel Production
May 18 — Much of the world’s oil reserves lies in giant tar sand stretches in places like Alberta and Venezuela. While the oil industry uses an energy-intensive and fairly dirty process to make steam to cook the oil out of the tar sands, underground bacteria simply eat the crude oil and break it down into methane, or natural gas.
In nature, that process takes millions of years. A small group of cross-disciplinary microbiologists with their feet both in the oil industry and academic geochemistry wants to speed up the work. They are trying to get these bugs to break down carbon much faster to produce a steady supply of commercial natural gas, and to enhance the recovery of crude.
Interest in using microbes that grow naturally in oil fields, coal beds and shale deposits is growing, according to a group of industry insiders at the Biotechnology Industry Organization (BIO) 2010 convention last week in Chicago.
“We’ve garnered the attention of large oil and gas producers around the world,” said Mark Finkelstein, vice-president of science at Colorado-based Luca Technologies. “The recent emphasis on climate change and natural gas bodes well for our technology.”
