Application of Tip Screen-Out Fracturing Technique
Tip Screen-Out (TSO) fracturing technique is used to deliberately create a proppant screen-out or bridging condition around the perimeter of the fracture to prevent further propagation and height growth. Continued pumping results in “ ballooning” or an increase in the fracture aperture with continued increasing fracture pressure. The increased aperture results in a greater propped width and increased fracture conductivity. The TSO designs are generally performed in moderate to high-permeability reservoirs that require greater conductivity than achieved with conventional hydraulic fracturing. The implementation of TSO over the past decade has resulted in substantially greater fracture conductivities and improved proppant placement. Consequently, these applications have gained popularity in the industry, especially in high permeability reservoirs, where inadequate conductivity and formation damage have been problems. The increases for width and conductivity also mitigate nondarcy (or turbulent) flow effects in the fracture for high-rate wells, particularly gas wells.
