Conventional completion techniques are time intensive, require tubing manipulation and multiple well interventions, which make them less than desirable for extended-reach and deepwater applications. The ideal setting method for extended-reach and deepwater applications requires a one-trip system where the packer is run in on the completion string, actuated, and set without any tubing manipulation or well intervention. No single conventional setting method meets these requirements. Electronically enhanced remote actuation allows for reduction, and in some cases total elimination, of common well-intervention operations. A new, mud-pulse-frequency-based communication technique that actuates and manipulates downhole tools equipped with onboard electronics has been developed. The downhole tools are programmed at the surface to recognize 1 of 16 discrete actuation commands from a computer-controlled, portable terminal unit. Once in position, the tools are actuated on receipt of a specific command sent from the portable terminal unit. As many as 16 devices can be activated independently of one another in a single wellbore. Pulse-communication technology can be adapted to many types of downhole completion devices, including packers, sliding sleeves, and temporary plugs.
