Devices, systems, and methods for gas lift gas

A gas lift gas recovery system comprising:

• an inlet separator system configured to receive production fluid for separation of liquids therefrom to recover gas lift gas, the inlet separator system comprising at least one separator vessel for receiving production fluid from a well and separating liquids from gas within the production fluid;
• a charge system including a high pressure (HP) leg for holding an HP portion of fluid and a low pressure (LP) leg for holding an LP portion of fluid, a liquid inlet for selective communication with the inlet separator system to receive liquids;
• and
• a sump system for holding liquids from at least one of the inlet separator system and the charge system, the sump system comprising a sump vessel arranged for selective communication with the charge system to transfer vaporous release to the charge system;
• a control system for operation to conduct selective communication of fluids, wherein the control system is configured to selectively communicate the sump system with at least one of the inlet separator system and the charge system to transfer liquids to the sump system;
• and
• a methane recovery system for recovering methane from at least one of the sump system and the charge system.

A gas lift gas preparation system comprising:

• a gas lift gas recovery system for recovering gas lift gas from well production fluid, the gas lift gas recovery system comprising:
• an inlet separator system configured to receive production fluid for separation of liquids therefrom to recover gas lift gas, the inlet separator system comprising at least one separator vessel for receiving production fluid from a well and separating liquids from gas within the production fluid;
• a charge system including a high pressure (HP) leg for holding an HP portion of fluid and a low pressure (LP) leg for holding an LP portion of fluid, a liquid inlet for selective communication with the inlet separator system to receive liquids;
• a sump system for holding liquids from at least one of the inlet separator system and the charge system, the sump system comprising a sump vessel arranged for selective communication with the charge system to transfer vaporous release to the charge system;
• and
• a control system for operation to conduct selective communication of fluids, wherein the control system is configured to selectively communicate the sump system with at least one of the inlet separator system and the charge system to transfer liquids to the sump system;
• and
• a gas compression system for compression of recovered gas lift gas from the inlet separator system, the gas compression system including at least one compressor arranged for communication with the inlet separator system to receive recovered gas lift gas, and in communication to provide compressed gas lift gas for gas lift.
