Abstract

See full text

A method of creating a step-change in proppant concentration in a fracturing fluid at a desired location within the conduit or wellbore of an oil or gas well includes connecting an in-line mixer at an end of a conveyance. The in-line mixer is then placed within a conduit proximate to the desired location, and a flow of a clean fluid is provided from an upper portion of the conduit past the in-line mixer and into a lower portion of the conduit. A proppant slurry is introduced into the conveyance and injected into the clean fluid from the in-line mixer to generate a first step-change from the clean fluid to a flow of a mixture of the proppant slurry and the clean fluid within the desired location.
