Abstract:
Low profile diverters for, and the use of such diverters in, fracing operations to stimulate production of oil and gas are capable of seating against and temporarily sealing perforations, even when frac fluid is being pumped at high rates and pressures, or in horizontal or highly deviated well bores, where conventional ball sealers cannot be reliably used because of high flow rates and pressures.

Claim (Index 1):
A method of stimulating production of hydrocarbons from a well having a casing through which has been formed a plurality of perforations, the method comprising:\n pumping into the wellbore under pressure a hydraulic fracture fluid containing proppant or an acid; after pumping a predetermined amount of the hydraulic fracture fluid containing proppant or acid into the well bore, introducing into the flow of hydraulic fracture fluid entering the well bore, without stopping pumping, a predetermined number of diverters for seating against a portion, but not all, of the plurality of perforations to obstruct and temporarily seal them, thereby diverting the hydraulic fracture fluid containing proppant or acid toward the remaining ones of the plurality of perforations not being obstructed; and continuing to pump the hydraulic fracture fluid containing proppant or acid under pressure into the well bore; wherein each of the diverters has, when seated on one of the plurality of perforations, a first surface facing the perforation opening and a second surface facing generally in the direction of a center line of the well bore, the area of the first surface being greater than the area of the perforation opening, and wherein each of the diverters, when seated, presents a cross-sectional area to the flow of hydraulic fracture fluid containing proppant or acid through the well bore during pumping that is substantially smaller than the first and the second surface areas.
