Geophysical response to simulated methane migration in groundwater based on a controlled injection experiment in a sandy unconfined aquifer
Klazinga, Dylan R.; Steelman, Colby M.; Endres, Anthony L.; Parker, Beth L. (Elsevier, 2019-09)Geophysical methods have the capacity to detect and characterize gas-phase dynamics in groundwater. Suitable methods can be deployed at surface or within boreholes depending on the required depth of investigation, ... -
Methane gas transport in unconfined aquifers: A numerical sensitivity study of a controlled release experiment at CFB Borden
Klazinga, Dylan R.; Steelman, Colby M.; Cahill, Aaron G.; Walton, Kenneth Mark; Endres, Anthony L.; Parker, Beth L. (Elsevier, 2019-08)Subsurface leakage of natural gas from petroleum wells can impact freshwater aquifers. Accurate prediction of gas migration in the subsurface will depend on knowledge of permeability, porosity, and flow system conditions. ... -
Monitoring the evolution and migration of a methane gas plume in an unconfined sandy aquifer using time-lapse GPR and ERT
Steelman, Colby M.; Klazinga, Dylan R.; Cahill, Aaron G.; Endres, Anthony L.; Parker, Beth L. (Elsevier, 2017-08-01)Fugitive methane (CH4) leakage associated with conventional and unconventional petroleum development (e.g., shale gas) may pose significant risks to shallow groundwater. While the potential threat of stray (CH4) gas in ... -
Numerical investigation of the geophysical response to methane migration in an unconfined aquifer with implications for hydrocarbon wellbore leakage
Klazinga, Dylan R. (University of Waterloo, 2018-05-10)Methane gas leakage from oil and gas development can impact freshwater aquifers. Accurate depictions of gas migration in the subsurface will depend on knowledge of physical parameters and flow system conditions. Geophysical ...
