HOUSTON – A new flow-channel hydraulic fracturing technique called HiWAY from Schlumberger is designed to maximize production by creating open flow channels within the propped fracture.
The technique changes the way fracture conductivity is generated, says Schlumberger, using a combination of placement, completion, fluid engineering, and process control to establish a network of stable channels within the fracture. The productivity is independent of the permeability of the proppant so that production flows through the channels rather than through the proppant pack. These channels extend from the wellbore to the end of the fracture, giving longer fracture half-lengths with better fluid and polymer recovery.
Schlumberger has successfully deployed HiWAY in Argentina, Russia, Mexico and the United States.
