A revolutionary cheaper way to find Oil and Gold!, by Keith Shaefer explains that: 

"A Saskatchewan entrepreneur could revolutionize oil exploration worldwide, with a new technology that uses readily available satellite data to determine if a property has commercial amounts of oil or gas underground.Robert Fisher, CEO of Leaf and Stone Resonance Services Inc.in Saskatoon, uses a process called “resonance coupling” that he says can tell if there is oil and/or gas on a property, onshore or offshore...The technology costs $100 per acre, and with oil companies paying up to $4,000 per acre in land costs for big resource plays in Canada (Cardium, Bakken etc), it could end up saving companies millions of dollars in exploration."
