Abstract: A pothead retaining sleeve apparatus, system and method. An electric submersible (ESP) motor pothead includes pivotable retaining sleeves, each pivotable retaining sleeve including a ball that seats within a socket inside the pothead, the ball rotatable in the socket such that each pivotable retaining sleeve is independently moveable around a spheroidal joint formed by the ball and socket. An ESP motor pothead system includes a pothead for electrically connecting a power cable to an electric submersible motor, each phase of the power cable extending through a retaining sleeve, the retaining sleeve extending through a conduit formed through an insulating block inside the pothead, the conduit including a spherical socket, the retaining sleeve including a tubular portion terminating at a ball seated within the spherical socket to form a ball and socket joint, and the tubular portion rotatable around the ball and socket joint during tying off of the phases.

Abstract: A pothead cable seal for electric submersible motors. An electric submersible motor pothead system including a pothead that couples a power cable to an electric submersible motor operable in well fluid, the pothead including a finger seal including a finger around each phase of the power cable and a radial flange, a compression plate that exerts a radial force on each phase from an axial load provided by the compression plate against the radial flange, a seal seat including sockets that receive each finger; a space extending between a portion of an outer diameter of each finger and a flared inner diameter of the socket of the seal seat, and a seal ring extending circumferentially around an outer diameter of each finger and tangent to the flange, the seal ring contacting the flared inner diameter of the seal seat and closing the space to the ingress of well fluid.
