| Abstract | Collected information during 2017-2018 provided interesting and unexpected results. For instance: 1) borehole logging in wells drilled with two different techniques provided different results. Thus, two
additional wells will be drilled next year to provide more info. This represents a great opportunity to reconcile data, as hammer-drilled wells are much less expensive than diamonddrilled wells, but validity of data from the former wells needs to be
ascertained; 2) results from barometric and water-level monitoring provided new information for the interpretation of the confinement conditions (unconfined, semi-confined or confined) of each well; 3) Regular groundwater monitoring revealed that,
contrary to what the traditional indicators such as gas dryness ratio and delta-13C(CH4) seemed to indicate, only one well would in fact contain thermogenic gas, while the other thermogenic?like samples would rather correspond to microbial methane
affected by oxidation, based on calculations using documented isotopic fractionation factors; 4) The study of the re-processed seismic lines led to the re?intepretation of the deformation of evaporite deposits of the Windsor Group and its impact on
sedimentary packages. |
| Summary | (Plain Language Summary, not published)
The Environmental Geoscience Program (EGP) provides scientific research projects by the Geological Survey of Canada to advance knowledge related to the
development of Canada's natural resources. The scientific breakthroughs presented at this annual meeting of the EGP are at the root of responsible resource management by the natural resources sector. The body of research also contributes to the
implementation of regulations that protect Canadians and their environment |
