ABSTRACT:
A system and method are provided for direct connecting downhole control hydraulics through an oil field hanger, where the hanger is coupled to a wellhead, to hydraulic lines extending outside the wellhead. Further, the direct connection allows hydraulic system integrity with reduced contamination and leakage. Hydraulic tool ports, formed on the hanger, are coupled with hydraulic lines extending downward to a hydraulic tool. Side ports, formed in the hanger, are fluidicly coupled to the hydraulic tool ports. Hydraulic lines extending outside the wellhead are directly coupled with the side ports by accessing the side ports through access openings in the wellhead when the ports are aligned with the access openings. The system can still maintain pressure within internal spaces of the wellhead after the connection by sealing the access openings with flanges, where the hydraulic lines extend through openings in the flanges that are also sealed around the lines.
