Self-Contained HydroFlame Process Development Using GAGD

One of the major bottlenecks facing CO2 EOR projects is the CO2 supply crunch, with most of these projects requiring pure CO2 for their operations. CO2 needed for these projects is mostly tapped from underground resources, defeating the “sequestration” benefit of CO2 EOR, which is touted as its secondary benefit. Furthermore, 293.2 Billion cubic feet of natural gas was flared/vented from just the Permian shale oil basin last year in 2019 and this number has been steadily trending up over the past 3 years. Due to lack of compression/pipeline infrastructure, this gas is flared rather than being piped to gas hubs for sale. Small to medium operators do not have the economic wherewithal to invest in these capital-intensive infrastructures and are content in selling the oil, which fetches a higher market price, in preference to gas. In the current tight oil production scenario, there is no economic incentive for the operators not to flare the associated gas and that is why we have been seeing the upward trend in flaring/venting over the years. GAGD which doesn’t need pure CO2 for its operation can help eliminate the flaring/venting by working in tandem with Hydroflame process. Rather than flaring, this natural gas would be diverted to a Hydroflame unit, that would use the energy content of the otherwise flared/vented natural gas for its operations and then use the burnt gases in a downstream GAGD process. This would help mitigate the colossal amount of flaring/venting ongoing in the shale plays. This holistic concept of produced water treatment, recycling and elimination of flaring in a self-contained process is illustrated below.

Self-Contained HydroFlame Process using Flare-Natural-Gas as Fuel
for Produced Water Treatment and Flue Gas Injection for Enhanced Oil

 

HydroFlame process would burn flare gas, that is currently being wasted in flares, in order to heat the produced water to knock out the calcium and magnesium carbonates and sulfates whose solubility decreases with increasing temperature. After utilizing their heat content, the exhaust flue gases from the HydroFlame unit will then be compressed and injected into oil bearing formations to produce oil thereby eliminating CO2 emissions.
