Gas emissions abatement systems and methods for repurposing of gas streams

Abstract

Systems and methods are provided for utilization in gas recovery conversion to truncate greenhouse emissions that result from gas flaring and venting in production operations. The disclosed stimulates responsible production versus unremitting flaring or venting that further burgeon emissions intensity. Industry lacks incentives and alternatives where common practice is to flare, vent to facilitate oil production. Flaring, venting augment methane emissions contrary to regulations. Seeking compliance but counter to national interests, producers can opt to shut-in or defer production. The systems and methods herein achieve exemplary processing, conditioning, compression, and storage of repurposed value-added gas streams to abate methane and other emissions intensity. The systems, methods and sequencing result in portable, scalable, autonomously operable well site configuration that repurposes surfacing gas volumes, and revalues reserves that would have otherwise been flared, vented, or abandoned. Abatement of methane and greenhouse gas emissions and their deleterious effects embedded in current hydrocarbons production.
