Abstract: A technique facilitates the anchoring and use of a downhole tool. The technique may be utilized with operations in which fluid is pumped or otherwise flowed through a tubular to the downhole tool. The operations are performed after the downhole tool has been fixed relative to the wellbore and while the tubular remains connected to the downhole tool. In some operations, the downhole tool is manipulated from the surface via the tubular to control placement of the fluid flowing down through the tubular.

Abstract: A valve assembly connectable between first and second downhole components that each have first and second internal flowpaths. The valve assembly comprises a first valve operable to selectively fluidly couple the first internal flowpaths of the first and second downhole components, as well as a second valve operable to selectively fluidly couple the second internal flowpaths of the first and second downhole components.
