Technology Description:

Cimarron Energy aims to develop a cost-competitive flare and control system to achieve over 99.5% methane destruction and removal efficiency (DRE) from the current 98% DRE. The proposed system will include a novel flare apparatus to overcome all observed difficulties in achieving high DRE for flares, a microprocessor based electronic controller, an image-based closed-loop feedback system, and flow meters for high-pressure (HP) and low-pressure (LP) flare gas streams sent to the flare. The HP gas is associated with oil extraction and contains a large fraction of methane. The LP gas is tank vapor from the crude oil storage tank and contains methane plus higher molecular weight hydrocarbons. The emissions performance of the flare and control system will be verified in oil fields. The proposed system and its components can be integrated with the majority of flares used in upstream oil and gas production sites.

Potential Impact:

REMEDY addresses methane emissions from domestic oil, gas, and coal value chains, accounting for 78% of U.S. primary energy.


REMEDY systems will reduce the environmental footprint from the production and use of domestic resources.


A key REMEDY process performance metric is to reduce net greenhouse gas emissions > 87% on a life cycle basis. This metric ensures proposed solutions provide a holistic environmental benefit. If successful, REMEDY processes have the potential to reduce U.S. methane emissions by at least 60 million tons of CO2e (carbon dioxide equivalents) per year.


REMEDY goals call for 87%+ methane reduction while meeting a levelized cost less than $40/ton of CO2e.
