Schlumberger

Schlumberger trucks with 2000 horsepower pumps direct water, sand and chemicals over 11,000 feet into the ground to create a fracture at a completion site on the Jonah Field in Sublette County, Wyo., pictured on April 9, 2015. The site currently operates four active drilling rigs on 24,000 acres of productive land with over 1,500 active wells that will consume roughly 2.5 million gallons of water and 3 million pounds of sand. In 2013, estimate proved reserves were over 1.5 trillion cubic feet equivalent of natural gas, making it the the eighth largest gas field in the North America and the fifth biggest oil producer in Wyoming. Jonah LLC completed the acquisition of the site from Encana Corporation in May 2013, and the deal included the adjacent Normally Pressured Lance (NPL) area of over 140,000 acres with the potential for 3,500 gas and oil wells.Alex Milan Tracy—Sipa/AP
