Downhole wireless communication techniques and electronically enhanced remote-actuation completion equipment reduce, and in some cases eliminate, many common well interventions. To cope with increasing operating costs, today`s oil and gas companies are looking for economical ways to minimize well interventions without compromising reliability, safety, or ultimate well profitability. This becomes more important in extended-reach wells where completions are run in ultra-long horizontal and near-horizontal well bores. An electronically enhanced remote-actuation system consists of a downhole module and a surface unit, connected by a primary communication medium. The downhole module contains the actuation system, control system, a power source, and a communication receiver. The surface unit contains the communication transmission device and, if necessary, associated control systems. The communication medium carries the command one way, from the surface to the downhole module. Currently, three wireless communication options are available for remote actuation systems: low-frequency electromagnetic fields, absolute pressure, and frequency-based pulse wave energy.
