1. A method for deploying submergible equipment, the method comprising the steps of:
- electrically and mechanically coupling the equipment to a lower interface member, the lower interface member including a first field matable electrical connector;
coupling a tensile support member to an upper interface member, the upper interface member including a second field matable electrical connector coupled to a power cable assembly;
coupling the upper and lower interface members to one another so as to mate the first and second connectors;
extending the tensile support member into an operating location; and
actuating a remote release assembly to uncouple the upper and lower interface members from one another and the first and second connectors from one another.

Abstract
A controlled release method for a submergible completion is disclosed wherein upper and lower interface assemblies are separated from one another in a predictable manner. A separation or release assembly is actuated remotely for forcing the interface assemblies apart. The release assembly may shear pins extending between portions of the interface assemblies. The interface assemblies may include multi-conductor electrical plugs or connectors which are separated during release.

14. A method for releasing powered submergible well completion equipment, the submergible well completion equipment being suspended in an operating location via a conduit and coupled to an above-ground location via at least one conductor extending within the conduit for supplying electrical power to the equipment, the method comprising the steps of:
-
providing an interface assembly coupled between the conduit and to the at least one conductor at a first end and to the equipment at a second end, the interface assembly including a remotely actuatable release assembly; actuating the release assembly to separate the equipment from the conduit and the at least one conductor. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method for controllably releasing a submergible pumping system deployed in a well, the pumping system being positioned in the well via a connection assembly secured to the pumping system and to a tensile support member, the method including the steps of:
-
providing a release assembly coupled to the connection assembly and actuatable by pressurized hydraulic fluid; applying a pressurized hydraulic fluid to the release assembly to displace a movable release element within the release assembly; and displacing the tensile support member with respect to the pumping system to release the pumping assembly. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
