ABSTRACT:
A cable that delivers power, signals, or information is wet connected downhole. The lower portion of the cable can be in an auxiliary conduit to a main tubular and be installed already connected to sensors, instruments or other downhole equipment. The connection is made up downhole to connect a string with its auxiliary conduit to the portion of the string and its auxiliary conduit that are below. The cable already in the hole has an upper end ferrule for connection to a ferrule on the lower end of a cable delivered into the upper auxiliary conduit after the wet connect is made up. When the ferrules connect they are held together and a signal goes to the surface that they have connected. The auxiliary connected conduits have a lateral conduit in fluid communication for use in delivery of the cable with circulating fluid.
