Project Description

C-Crete Technologies is developing a new protocol integrating a collection of advanced synthesis and characterization techniques, a thorough combination of lab-simulation and field tests, as well as cost-benefit and socioeconomics analysis to achieve the most beneficial and cost effective CO2 barrier technology. The core synthesis strategy is a bottom-up approach to further develop the knowledge base related to nanoparticles and nanocomposites and apply it to a new cement-based porous nanoparticles (CPNP)-sealant product (Figure 1). The technical results are being coupled to a cost-benefit/ socioeconomic analysis that incorporates materials/method cost structures and risk and environmental priorities to quantitatively evaluate the impact and benefits of the new product and technology.

Project Benefits

This project is providing a new phase space that provides a paradigm for material design and engineering to mitigate wellbore leakage in existing wells and improve reservoir efficiency. A CPNP-sealant material that is able to be pre-programmed using a range of ingredients to best fit it to various complicated well/reservoir environments. The environments are found under a variety of temperatures, pressures and chemical conditions. The final CPNP-sealant product will be easily integrated to existing remedial technologies to efficiently mitigate CO2 leakage to meet the DOE’s Carbon Storage Program goal of 99 percent storage permanence.
