Research

The SaskCO2USER Project is grounded in seven key areas of research:

This research project led by the principal research team at the Gulf Coast Carbon Center at the Bureau of Economic Geology used the complex data sets extensively catalogued at the Weyburn and Midale fields. The project applied a risk-informed, system approach to determine minimum data set requirements for leakage detection and developed a modeling workflow for CO2 migration during post CO2-EOR storage.

This project, conducted by Schlumberger Carbon Services, used available data from the twelve years of research to provide guidance to CO2-EOR operators on cost effective monitoring strategies for the long-term storage of CO2.

This area of seismicity is related to the underground injection of fluids which includes CO2, waste fluids and brine that have become a heightened interest in CO2 storage projects. Under the leadership of the University of Bristol and Outer Limits Geophysics LLP, the natural seismicity of southern Saskatchewan was compiled and reviewed.  This data set was cross-referenced with a historical record of the regional fluid injection.

 Dutch-based TNO is advanced existing work at Weyburn. By adapting the existing algorithm, a history-matching method was developed with the goals of being flexible, efficient and effective. This algorithm was demonstrated on a synthetic data set before being applied to data from an operational CO2-EOR field.

Managed by Bissett Resource Consultants Ltd., the objectives of this wellbore project included: analyzing methods which provide an effective and reliable seal for CO2 and other injected fluids; a basic drilling program which would be used as a model for future operators; cost estimates; options for future horizontal well designs; and completion and abandonment procedures, tools and materials.

This Energy and Environmental Research Center (EERC) - led project focused on improving operational economics and mitigating the impacts of casing corrosion. By comparing case studies and in-situ results with existing laboratory work, scenarios emerged that were relevant to real-world experience.

This project, conducted by the Saskatchewan Geological Survey, investigated the effect of injected CO2 on rock framework and pore space.
