A New Reality for Fracturing Fluids | Schlumberger

The chemical engineering objectives of a ,fracturing fluid, fall into three categories: Initiate and propagate a hydraulic fracture; Convey a propping ,agent, into the fracture; and; Ensure the proppant pack and formation connect efficiently to the wellbore with minimal damage. Most optimization has historically concerned the first two points.
