GEOLOGIC CARBON STORAGE (CS)
What is CO2 Sequestration?
Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide (CO2). It is one method of reducing the amount of CO2 in the atmosphere with the goal of reducing global climate change.
Geologic storage of CO2 is quickly becoming a crucial technical strategy for guaranteeing environmental sustainability by minimizing greenhouse gas emissions. It is necessary to develop technologies that will allow commercial deployment of CO2 subsurface geologic storage. Identifying ideal sites with adequate storage necessitates a rigorous and careful examination of the technical and non-technical characteristics of promising storage sites.
What We Do
Our team of CO2 subject matter experts provide a holistic approach or guidelines to carry out geologic storage projects, from inception to completion conduct.
For geologic storage projects, the workflow involves Site Screening, Site Selection, and Site Characterization. These stages correspond to three sub-classes within the Prospective Resources classification: Potential Sub-Regions, Selected Areas, and Qualified Sites, in descending order.
HOW WE DO IT
Site screening is the evaluation of Potential Sub-Regions within a larger area, such as a basin, in order to find Selected Areas that may be ideal for geologic CO2 storage.
During site selection, designated Selected Areas are assessed to see if a potential storage site can be discovered utilizing prior research and additional, existing data. Technical data that should be considered include information from available core samples, seismic surveys, well logs, records, and sample descriptions from active or plugged & abandoned wells, as well as other geologic data that is currently available. This stage will conclude with a list of the most promising Potential Sites to be evaluated during Site Characterization.
The CS team continues the evaluation of one or more of the higher-ranked Potential Sites in the final step, Site Characterization. Our team conducts a full site-specific examination of all geological issues for the selected Potential Sites at this stage, and either confirms or rejects a site as acceptable for designation as a Qualified Site. While the analysis in Site Screening and Site Selection is primarily based on existing data, Site Characterization will almost certainly require the acquisition of new, site-specific data (e.g., seismic, well logging, core analysis, injectivity tests) as well as the development of 3D models of the selected injection and confining zones.
