Abstract
A slip assembly adapted to be used with a downhole tool which comprises metal slip inserts attached to a slip carrier made of a non-metallic material, such as composite material. As such, the non-metallic slip carrier can eliminate 60-70% or more of the metal used in conventional slip assemblies. Through use of the disclosed slip assembly, downhole tools may be set, while also reducing the metallic material used therein and, thus, greatly reducing the drill out time.
