The present invention addresses to an improvement in a conventional packer, comprising the installation of an upper connector, a lower connector and an inner tube, adapted to allow the passage of hydraulic control lines and/or electrical cables internally to the packer mandrel, without interference with the passage of tools or flow. The conventional packer transformed according to the present invention aims at allowing controlling, from the surface, hydraulic equipment (sliding sleeve valves) or transmitting/receiving data from flow rate, pressure and temperature sensors (PDG—Permanent Downhole Gauge) that are positioned in the production string below the packer. The packer according to the present invention comprises an adapted upper connection (40), an adapted lower connection (50), and an inner tube (62), through which control lines or electrical cables internally pass.
A BOTTOMHOLE PACKER ADAPTED FOR SMART COMPLETION, characterized in that it comprises an upper adapter (40) fixed and screwed to the mandrel (64) of the packer (80) and a lower rotating adapter (70) and (50) also attached to the mandrel (64) of the packer (80), and an inner tube (62) sized for the length of the packer (80) and the internal diameter of the production or injection string, through which control lines or cables (60) internally pass from the PDG (Permanent Downhole Gauge) sensor (82), commanding hydraulic equipment (sliding sleeve valve) or transmitting data from PDG sensors (82) installed in the string that are positioned below or between packers.
