Abstract: A packer has a tubular body and a setting sleeve disposed around the tubular body, where the setting sleeve has an upper end, a lower end, and a slot formed through a wall of the setting sleeve. The slot has a perimeter defining a shape of the slot, the perimeter having a top wall with a positively sloping portion extending to a top peak. The slot shape also includes a first axial extension extending axially along the sleeve from a first upper portion to a first lower portion, a second axial extension circumferentially spaced apart from the first extension and extending axially along the sleeve from a second upper portion to a second lower portion, and a lateral extension extending from the first upper portion to the second upper portion. A load pin is directly or indirectly connected to the tubular body and extends through the slot.

Abstract: A technique facilitates generation of electric power in well environments. The technique involves combining a cooperating stator and rotor assembly to create an electromagnetic generator. The cooperating stator and rotor assembly utilize an electromagnet which works with a generator coil to create electrical power. Use of the electromagnet enables the electromagnetic field created during generation of electrical power to be selectively eliminated. Elimination of the electromagnetic field allows magnetic particles to be freely flushed from the electromagnetic generator.

Abstract: A completions assembly having an autonomous self-sustaining portion powered by an atomic battery. The atomic battery may be of a non-based beta voltaic variety configured to provide uninterrupted power to the autonomous portion of the assembly for substantially the life of the well. Thus, continuous monitoring of well conditions or low power actuations, via sensors and/or actuators of the autonomous portion, may be supported. As a result, the autonomous portion may be operated in a fully wireless manner without the requirement of hard wiring to the main bore/surface connected portion of the completions assembly.

Abstract: A technique facilitates providing a downhole completion with electrical power. The technique may comprise placing an independent completion in a wellbore section. The independent completion is provided with a removable power unit having a power generator coupled to a power storage device. The technique further comprises communicating data or other signals between the independent completion located in the wellbore section and a second completion located in a separate wellbore section.
