Abstract
Implementations described and claimed herein provide systems and methods for increasing production performance in a Steam Assisted Gravity Drainage system. In one implementation, an upper mating unit of an inverted shroud assembly is received with a lower mating unit of the inverted should assembly in a slidable relationship. The upper mating unit is coupled to a pump-intake assembly. The lower mating unit is coupled to a motor-seal assembly. The slidable relationship secures the pump-intake assembly to the motor-seal assembly. A motor of the motor-seal assembly is directly cooled by opening the motor to a production well based on an exterior attachment of the motor-seal assembly relative to an inverted shroud.
Claims19
A system for increasing production in Steam Assisted Gravity Drainage operations, the system comprising:
- an inverted shroud configured to contain a pump-intake assembly of an Electric Submersible Pump;
- a lower mating unit coupled to the inverted shroud and configured to couple to a motor-seal assembly of the Electric Submersible Pump opposite the inverted shroud;
- and
- an upper mating unit disposed within the inverted shroud and configured to couple with the lower mating unit and the pump-intake assembly.
A method comprising:
- coupling an upper mating unit to a lower mating unit, the upper mating unit configured to couple to a pump-intake assembly;
- coupling the lower mating unit to an inverted shroud, the lower mating unit configured to couple to a motor-seal assembly;
- securing the upper mating unit within the inverted shroud;
- and
- increasing production in a Steam Assisted Gravity Drainage operation based on a relationship between a first outer diameter of the inverted shroud and a second outer diameter of the motor-seal assembly.
A system for increasing production in Steam Assisted Gravity Drainage operations, the system comprising:
- an inverted shroud configured to house a pump-intake assembly;
- a lower mating unit coupled to the inverted shroud and configured to be secured to a motor-seal assembly via an exterior attachment relative to the inverted shroud;
- and
- an upper mating unit disposed within the inverted shroud, configured to couple to the pump-intake assembly.
