Patent ID: 8453742

Claim:
A standing vortex apparatus for selective fluid diversion in operations in a wellbore having a wellbore inner diameter, the wellbore being disposed in a hydrocarbon producing strata, the standing vortex apparatus comprising: a body operable to be disposed within the wellbore, the body having an outer surface, the outer surface capable of rotation about a longitudinal axis of the body, the body having an outer diameter that is less than the wellbore inner diameter, such that when the body is disposed within the wellbore, an annular area is created between the outer surface of the body and the wellbore inner diameter; a fluid delivery injection system in fluid communication with the body, the fluid delivery injection system operable to deliver an erosive fluid to the annular area; and a means for rotating the outer surface about its longitudinal axis at a predetermined speed, such that circulation of the fluid in the annular area is controlled.
