Periodic Report Summary 2 - TRUST (High resolution monitoring, real time visualization and reliable modeling of highly controlled, intermediate and up-scalable size pilot injection tests of underground storage of CO2)

Project Context and Objectives:

Design and implement a new integrated active and passive seismic monitoring system. Develop the (Kinetic Interface Sensitive) KIS tracers.

Determine of permeability changes as a proxy for the extent of the CO2 plume. Integrate surface and downhole measurements and monitoring results in an internet platform with online and real-time visualization tools. Model and modeling approach development, evaluation and validation against comprehensive sets of field data; Development of approaches for long-term and large scale (industrial) predictions of CO2 injection and storage. Design simulations of injection experiments, including testing of different injection scenarios. Interpretation and model matching of the injection experiments; Development of the operational models for the sites for large-scale and long-time predictions; Providing a field data case for model cross-validation and providing a first approach for such cross-validation.

Define optimal injection strategies and modes of injection in order to maximize the trapping while minimizing the reservoir pressure build-up and minimizing the energy usage and other major costs of the operation. Test some of the key injection strategies at Heletz. Extend the analyses, by means of modeling, to other conditions and site characteristics. Analyze results and suggest recommendations on best practices for injection, from the outlet of the supply line to the reservoir and the related pressure management.

Develop a new technology for remediation based on reactive fluid injection (self-carbonation solute). Determine the optimal fluid formulations and uses according to the local hydro-thermo-chemical properties of the reservoir. Conduct a controlled experiment of CO2 leakage in a poorly plugged or unplugged well at CNRS.

Develop and implement a site specific risk management procedure Heletz site, aimed at achieving a comprehensive risk assessment process, controlling and monitoring, communication of information, handling and minimizing residual risks (especially downhole, near the wellbore, and within the caprock) and detecting and handling possible failures of the seal or near-well completion. Use the risk management findings as input for further applications such as the development of guidelines, protocols for site licensing and certification, liability issues.

Ensure broad visibility of TRUST, by establishing a solid platform for sharing knowledge within the consortium as well as for reaching the widest audience possible, by means of modern IT technologies and social networks. Address issues of communication, social acceptance and liability in order to enable the project partners to fulfill their communication efforts and stakeholder involvement tasks.

Promote education, training and capacity building in the field of geological storage of CO2. Promote education and competence building by organizing formal educational courses for the international forum and related to this, develop course material for teaching. Promote education and competence building by affiliating of PhD students, Post-Doctoral scientists and Master students to the R&D work of TRUST.

Extrapolate the results of the project to the industrial scale application as well as to develop generic approaches for such upscaling. Upscaling of the monitoring strategies and network design for large scale; Preparation of protocols for site management; Formulation of best practices and recommendations and exploitation of results.

Project Results:
The consortium agreement was completed. The project manager and the Project Steering Committee carried out the project management according to the plan and without unsolvable problems. The Heletz facility instrumentation is now completed. We tested the monitoring technologies and prepared protocols for fluid sampling online onsite and analysis and storage for out of site analysis. The drilling of the shallow wells, to be instrumented for seismic monitoring is completed. The manufacturing of the downhole Electrical resistivity and Bragg sensors is completed. These have been successfully tested at the shallow site of Maguelone (France). The implementation of an active and passive seismic monitoring system is completed and will be deployed at Heletz during the winter of 2016. The development of KIS (Kinetic interface tracers) is continuing at the laboratory level. The use noble gases as tracers for the injection experiment at Heletz has been developed both at the modeling level and at the field level. The development of pressure tomography has been extended to heterogeneous formations and analyzed via modeling. The online visualization platform development has started and is tested at Heletz. A comprehensive set of simulations was carried out, to investigate the effect of different modes of injection to enhance trapping, with the objective to provide design guidance to Heletz CO2 injection experiments, including the impact of the temperature of the injected CO2. Model development included the integration of poro-elastic and thermo-elastic coupling terms into the IC Geomechanics Toolkit and the development of a more versatile code for the simulation of the reservoir and wellbore. Optimization of injection by temperature control, setting constraints on reservoir stability. We are developing combined models of capillary and dissolution trapping for the assessment of their combined impact on CO2 propagation and the concomitant risks of leakage. Simultaneously, we have developed stratified models of the flow of CO2-saturated brine, a key ingredient to predicting the rate at which CO2 may dissolve from the capillary fringe. The shallow wells located at CNRS premises have been prepared for the leakage mitigation experiment. Protocols for the injection of the mitigating solutions have been developed. The mitigating solutions have been developed and tested at the laboratory scale and procurement of the raw materials for the field experiment are underway. A strategy for the risk management at a CO2 injection site has been developed. It includes also the site management aspects. A specific procedure for the risk management at Heletz has been delineated and implemented on site. The project web site was completely redesigned and uploaded. Twitter and linkedIn were open. Public outreach has been dealt by approaching key experts in this area to our consortium meetings. An investigation of the liabilities problem for site certification and licensing has been completed. It identifies the existing regulatory framework in Israel that could be further developed to cover CO2 storage. A preliminary document for the establishment of an educational center at Heletz was outlined. The second TRUST course on CO2 storage was held in October 2015 in Montpellier with a substance participation of 29 students. Scientific dissemination included the contribution to a CCS book (Niemi, Bear and Bensabat, Springer, 2016), a special issue of the International Journal of Greenhouse Control (Niemi, Gouze and Bensabat) and a substantial number of peer-reviewed papers in scientific journals. Several evaluations of storage capacities have been conducted. Investigations on how to upscale local data to reservoir scale have been suggested. A statistical analysis of the TORIS database in order to understand typical characteristics of reservoirs has been conducted. Models are being tested for large scale industrial simulations of CO2 storage.
