Linc Energy is the world leader in UCG for cleaner energy solutions like power generation and fuel production. As a company Linc Energy is always looking for ways to innovate its activities to new heights for better commercial outcomes. Upon reviewing Enhanced Oil Recovery (EOR) and its capabilities, Linc Energy has diversified its business strategy to become the leader in both UCG and EOR.
In basic terms, the primary waste product from UCG is carbon dioxide, which can be used in the EOR process to sweep stranded, remaining oil from near depleted oil fields. With Linc Energy’s accelerated presence in the United States and leading capabilities in UCG, it makes perfect sense for the company to use high value carbon dioxide from UCG for EOR.
In a commercial sense, using carbon dioxide from the UCG process ensures that nothing is wasted. Just as UCG unlocks the energy trapped in deep coal, too deep to mine, carbon dioxide can be inserted into depleting oil fields to harvest the remaining oil. The EOR process can draw an additional 10 to 20 per cent of the original amount of oil already taken from a well.
From an environmental point of view EOR is a form of carbon capture and storage. By their very nature, oil fields trap fluids, like oil, in the subsurface. The oil migrates from the source to a place where it can no longer move. This is known as a geologic trap. It is this same ‘trapping’ tendency that makes old oil fields the perfect place to inject carbon dioxide, because when you put it there, it stays there.
As a diversified energy company, Linc Energy is certainly doing its part to be as productive and environmentally conscious as possible. Any carbon dioxide that Linc Energy can sequester to generate more energy to help supply traditional global needs is a positive step. Quite simply, Linc Energy is turning what could be simply ‘waste’ into a useful substance to produce more energy.
