Multi-functional sleeve completion system with return and reverse fluid path

Abstract

Provided is a multi-functional well completion apparatus and method of operation thereof that offers the ability, in a single trip and with limited running tool manipulation, to perform a sand control frac or other fluid stimulation operation and reverse out operations that has improved reverse out flow rates. Furthermore, a combination of dropped balls and hydraulic pressure open one or more sleeves for selective access to a plurality of isolated zones. Additionally, a combination of concentric pipe and internal flow paths creates a reverse flow path. This reverse flow path provides a live annulus during treating, the ability to take returns, and the ability to reverse excess proppant from the wellbore.
