Abiotic geological sequestration takes on a similar method to storing carbon dioxide in formations. It consists of the liquefaction, transportation, and insertion of carbon dioxide into geologic layers. There are essentially four different geologic formations in which carbon dioxide can be injected into, old oil wells, coal seams, inert rock layers, and saline aquifers. The saline aquifers are positioned beneath reservoirs of freshwater with a water-resistant layer in between. Subsequently, carbon dioxide can then be injected into the aquifer to be sequestered by the brackish water. The carbon dioxide that is pumped into the saline aquifer is in such a state that the liquid it is being injected into has a higher density and viscosity. Additionally, it creates a gas and dissolves in the aqueous phase creating an environment that has multiple mechanisms. Another way to utilize carbon sequestration is to force carbon dioxide into reservoirs in order to dislodge oil or gas reserves for an economically profitable strategy also known as enhanced oil recovery (EOR). The aforementioned technique has the ability to increase the yield of dwindling or high viscosity fields, as well as, capture the carbon dioxide that would otherwise enter the atmosphere. This method of flooding carbon dioxide is one of the most prominent techniques of carbon sequestration because the technology for it has been developing for 40 years. Therefore, it has increased in efficiency and effectiveness, while…
