US Patent 11248436 Frac diverter

A technique facilitates use of a frac diverter instead of a frac plug in a variety of fracturing operations. The frac diverter has a simpler and less expensive construction. Although the frac diverter may not form a seal with the surrounding casing in some applications, the frac diverter is able to sufficiently restrict flow of fracturing fluid to enable a successful fracturing operation. The frac diverter may comprise arrangements of at least one cone, at least one slip ring, and at least one corresponding sub which work in cooperation with a flow restricting element. The flow restricting element may comprise various types of rings, e.g. sealing element rings, able to sufficiently restrict flow of fracturing fluid past the frac diverter.
