Stranded Well Gas
Poor performing or remote wells are perfect candidates for our technology.
Stranded wells can be defined in two ways. The well is drilled and is either “low-btu” and below the required heating value limit to be injected into the pipeline or blended with other gas, or the well is located too far from the pipeline to justify extending a connection. Prometheus technology allows stranded well owners to recover their investment. This is significant as there are thousands of wells in the US that can be classified as stranded.
Prometheus’s stranded well-to-LNG system offers flexibility and outstanding economics to the end user. Although the natural gas supply is projected to last for the next 100 plus years, sometimes retrieving it is not economically or environmentally feasible. Because of its modular-scale principle and skid mounted systems, Prometheus can bridge this economic and accessibility shortfall.
Our Stranded Well Gas system is very similar to our Landfill Gas system, however, these gas resources do not have many of the volatile organic compounds as found in landfill gas. We can essentially eliminate much of the up-front purification necessary to process the gas.
Prometheus’s technology provides unique opportunities to develop a variety of potential feedstock sources to produce LNG for a diverse range of energy markets. By tapping waste gas and low-cost feedstock sources, Prometheus can offer unmatched economic and environmental benefits to end-users and other stakeholders.
