CO2 Storage in Depleted / Depleting Oil and Gas Fields
The high-level and seasoned consultants of A&A Consulting Team who have been working on CO2 projects, around the world, since the 1970s, have been providing state-of-the-art consulting services on CCS/CCUS, CO2 EOR, and other related projects, around the world, for many years. But 2022 has generated unprecedented momentum behind CCS/CCUS projects, not only in the US, but around the world, and A&A Consulting Team of high-level and seasoned consultants is delighted to be helping some of the major energy companies on their challenging CCS/CCUS projects.
Characterizing Depleted / Depleting Oil and Gas Fields for CO2 Storage
The high-level and seasoned consultants of A&A Geomechanics, Geosciences, Reservoir and Production Consulting Teams are experts in characterizing all aspects of depleted/depleting oil and gas fields, including, but not limited to:
• Site selection – primary and contingency storage sites with sufficient injectivity, storage capacity, and ability to contain CO2 for long period of time
• Reservoir characterization – porosity, permeability, heterogeneity, salinity
• Seal characterization – extent, sealing capacity, secondary seals
> Requires characterization of overburden
• Structural characterization – CO2 migration potential and path
• Formation mineralogy – reactions with CO2 and potential impact on injectivity and storage security
• Fault characterization – sealing capacity and potential for re-activation
• Hydrodynamics – can be advantageous, where is the water headed?
• USDW characterization
• All other related issues
