Oil and gas exploration has taken off this year, amid mutterings of phrases like "peak oil" and "solar power." Analysts estimate that the top independent oil and gas producers spent between 13% and 15% of their capital spending on exploration, up from 8.6% in 2005. The spending has paid off, and discovery after discovery should prompt investors to check out the best E&P outfits as potential investments.
