Core Laboratories is offering an industry led consortium to address and understand the risks and challenges associated with geological storage of CO2. Each year the topics are voted on by member companies. Historical year’s programs will be accessible by new members.
Modeling and Upscaling
- Nitrogen and CO2 Flow Comparisons – Relative permeability testing using a variety of methods to determine whether and under what conditions nitrogen can be used as a proxy for supercritical CO2
- Sensitivity Analysis – Reservoir modeling to determine sensitivity of plume size and injectivity properties to various input parameters related to relative permeability testing
- Mineralogical modeling – Development of a model to predict reactions between supercritical CO2 and various rock minerals matched to results from flow tests
Injectivity and Flow
- Geochemical Alterations – Determine the geological, petrophysical, and geomechanical changes from mineral dissolution and precipitation
- Relative Permeability – Assessment with physical lab measurements and digital evaluations on mobility of CO2-brine-oil including trapping,dispersion and fingering of CO2
- Solubility – Evaluate the extent of CO2 solubility in various brines and hydrocarbons
Aquifer Seal Analysis
- Geochemical Alterations – Determine the geological effects on seals with extended exposure to low pH fluids
- Seal Capacity Limits – Measure Threshold Entry Pressure on aquifer seal layers using low pH fluids, while monitoring changes over extended exposure times. Measure Interfacial Tension and Contact Angles on CO2 water samples for more accurate seal capacity simulations.
- Seal Capacity Calculator – Capillary Pressure Toolkit with ability to modify interfacial tension and contact angle for CO2 capacity evaluation from MICP data
- Seal Capacity Analogs – Deepwater Seal Analog data set available to consortium members
- Cement Integrity – Address leakage hazards on legacy wellbores and provide quantitative comparisons of cement blends
