Abstract (en)
[origin: WO2013155343A1] A method and apparatus is disclosed for remotely and selectively controlling fluid flow through tubular string disposed within a wellbore and further control fluid flow between the tubular string inner flow passage and the annular flow passage. The present invention further discloses a method of selectively and remotely receiving and interpreting a form of command or information at a desired apparatus within the wellbore caused by the operator on earth surface.
