Finding the right ,fracturing, recipe can help achieve even flow distribution and cluster efficiency, both of which can help contribute to increased production. “You want to ensure that you’re engaging the different clusters within a stage effectively and trying to get even flow across those clusters,” said Scott Gale, senior strategic business manager, production enhancement at Halliburton.

Effectively, the fracking process is pushing the water down into the rock formation, trying to wedge the rock cracks open. The sand fills in between the cracks that the hydraulic fluid has propped open. Once the fracking is done, much of the water comes back up the well as flowback wastewater.

The major part of these ,flowback, fluids were subjected to treatment in a special station in the well site area and stored for reuse in hydraulic ,fracturing, to be performed on other wells. The rest was treated as industrial waste ,fluid, and sent to be subjected to specialized methods of ,utilization,.

The hydraulic fracturing fluid shifts the pressure created into the groundwater to build fractures in the rock formations of the reservoir and to hold and position the proppant in the splits so that they stay “propped” exposed after the injecting pressure is turned off (Koplos, Tuccillo, and Ranalli).

Hydraulic fracturing technologies use a fluid as the medium to break reservoir formation. Hydraulic fractures are created by the means of fluid injection. It is accomplished by thrusting the fracturing fluid into the drilled borehole with a force high enough to elevate downhole pressure to surpass the strength of the formation (fracture pressure).
