“Pumping the volume of water we pump is probably unsustainable, not just in the US but internationally,” Schlumberger vice president of unconventional resources Chris Hopkins said during a conference in Houston.

Hopkins offered Schlumberger’s new Hi-Way fracture technology, which uses different linking agents to push pulses of proppant with the water, as one example of how industry can improve.

Across about 1900 fracturing jobs, the system has saved more than 60 million gallons of water and 200 million pounds of proppant, he said.
