Abstract
Official abstract text for this publication.
A downhole tool for removing debris from a wellbore comprises a body having a bore, a collection member, and a means for creating a hydraulic barrier within a wellbore annulus. The hydraulic barrier within the wellbore annulus restricts upward movement of a debris laden fluid within the wellbore annulus causing the debris laden fluid to be directed toward the collection member. Thus, the hydraulic barrier facilitates removal of debris from the wellbore.
First claim
Opening claim text (preview).
What is claimed is: 1. A downhole tool for capturing debris within an annular space, defined between an outermost surface of the tool and a wall defining the surrounding wellbore, the downhole tool comprising: a mandrel having an upper end, a lower end, a mandrel bore defined by a mandrel inner wall surface and at least one port extending from said bore on said inner wall surface to an outermost wall surface of the tool such that flow through said port creates a hydraulic barrier…
