Abstract:
1. A subsea wellhead assembly provided on a borehole, the assembly comprising: a tree on a wellhead housing; tubing extending into the borehole; casing circumscribing the tubing to form an annulus therebetween; an annular member having a portion circumscribed by the tree; a bore axially formed through a wall of the annular member; an electrically conductive member disposed in the annular member bore and in electrical communication with a device disposed in the borehole; a connection having an end in electrical communication with the electrically conductive member, the connection comprising an annular ring connectable with a ring contact; a tubing hanger coaxially circumscribing the lower end of the annular member; a bore axially formed through a wall of the tubing hanger; an electrically conductive member in the bore in the wall of the tubing hanger; a second connector having one end connected to the electrically conductive member in the bore of the tubing hanger and an opposite end connected to the electrically conductive member in the annular member bore; and a feed member in electrical communication with the end of the connection opposite the electrically conductive member, so that the feed member is in communication with the borehole device when the annular ring and ring contact are connected.
