"In Exxon Deal, Signs of the New Gusher"
"Over the last decade, a handful of the nation’s small energy companies pulled off a coup. Right under the noses of the industry’s biggest players, they discovered huge amounts of natural gas in fields stretching from Texas to Pennsylvania.
One of these companies, XTO Energy, grew almost unnoticed into the nation’s second-largest gas producer, amassing a substantial portfolio of gas fields, and developing expertise in the complex technology needed to extract the gas from beds of a dark rock called shale.
Now, the biggest energy companies are paying attention.
Exxon Mobil, the world’s largest publicly traded oil and gas producer, said Monday that it had agreed to buy XTO in an all-stock deal valued at $31 billion, the biggest oil and gas deal in four years."Source: NYTimes, 12/15/2009
