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 12):
A method of stimulating production of hydrocarbons from a well bore having a casing, the method comprising:\n establishing within the well bore a plurality of frac stages isolatable from each other; and for each of the plurality of frac stages,\n forming a plurality of perforations in the casing along a first section of the well bore; \n pumping into the wellbore under pressure the predetermined amount of a hydraulic fracture fluid containing proppant or acid; and \n after a predetermined amount of hydraulic fracture fluid containing proppant or acid has been pumped into the well bore, introducing into the flow of hydraulic fracture fluid containing proppant or acid entering the well bore, without stopping pumping, a batch of diverters, the batch of diverters containing fewer diverters than the number of perforations in the plurality of perforations for seating against a portion, but not all, of the plurality of perforations to temporarily obstruct and seal them at least partially, thereby diverting the hydraulic fracture fluid containing proppant or acid toward the remaining ones of the plurality of perforations not being obstructed for fracturing the subterranean formation adjacent to them; and \n continuing to pump the hydraulic fracture fluid containing proppant or acid under pressure into the well bore; \n wherein each of the plurality of 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 hydraulic fracture fluid flowing through the well bore during pumping that is substantially smaller than the first and the second surface areas.
