Title: Senior Geoscientist
Group: Clean Fossil Fuels, Subsurface Environment Team
Technology: CO2 storage, geothermal, and tight oil and gas

Andrew Wigston has a M.Sc. in Earth Sciences with a focus on sedimentology, geochemistry, and hydrogeology from Carleton University. He is a member of CanmetENERGY-Ottawa’s Subsurface Environment Group.

The focus of his work is the investigation of subsurface impacts of impurities in CO2 streams, in order to determine acceptable purity standards toward the end goal of reducing the cost of capture and purification. This work involves exposing reservoir, caprock, and wellbore materials samples to various CO2 streams in the group’s static high temperature reactor system and core-flood unit. The work also involves geochemical modeling as well as the analysis of liquid, gas, and solid samples via a suite of characterization methods.

In addition, Andrew is involved in improving wellbore integrity R&D, with the goal of reducing fugitive methane emissions. Alongside an industry partner, he is currently co-leading a Technology Roadmap to Reduce Wellbore Leakage. Furthermore, he is investigating novel wellbore remediation methods, including microbially-induced calcite precipitation.

Prior to CanmetENERGY, Andrew worked as a geologist in environment consulting on contaminated site assessment and remediation. He was heavily involved in the Geoscientific Site Characterization program for the Deep Geological Repository for low-level nuclear waste at the Bruce nuclear power generating site in Tiverton, Ontario.
