World's Most Powerful Land Drilling Rig
The world's largest oil company recently broke its own industry record for the longest "extended-reach" oil well. Such wells begin vertically on land and then curve to bore through layers of rock under the seabed to offshore reservoirs.
Exxon Mobil Corp.'s reach now stretches farther than anyone else's, more than seven miles from the frigid shores of Sakhalin Island off Russia's east coast, where the Chayvo oil field holds potentially a billion barrels of oil.
The well is 8,350 feet beneath the Sea of Okhotsk and 38,322 feet from shore to reservoir - about the length of 125 football fields. It blows past Exxon's previous record of 37,016 feet.
"It's almost an underground pipeline," said Joel Kiker, vice president of drilling for Exxon Mobil's development arm.
The 230-foot-tall Yastreb rig on the Chayvo project, operated by Houston-based Parker Drilling, also holds a title — the world's most powerful land drilling rig.
