A method for installing an electric submersible pump (ESP) in a well includes installing a plug in the well below a well tree. An upper and lower master valve on the tree are closed. Closure elements are removed from the lower master valve and replaced with gate seats, and a replacement gate block. The replacement gate block has a seat for a cable hanger. The upper master valve is opened. The plug is removed and the ESP extended into the well on an electrical cable. A cable hanger is affixed to the cable and is seated in the seat. The cable hanger has sealing elements to engage the seat and an electrical connector. The electrical connector is oriented to enable access through a side opening in the replacement gate block.

Method and system for deploying an electric submersible pump in a live well

Master valve and cable hanger system for deploying and making electrical connection to an electric submersible pump. A landing for the cable hanger () is in the through bore below the valve closure element. The landing has a seal area and a bore transverse to the through bore penetrating into the seal area for allowing electric connection to the pump. The cable hanger has a seal section having longitudinally spaced apart seals engageable with an interior of the seal area, electrical contacts disposed between the seals, and a lockdown profile. Flow ports are arranged to bypass seal area and seal section. A blanking plug () is disposed in the transverse bore to seal the seal area prior to insertion of the cable hanger.
