Abstract
Steam assisted gravity drainage (SAGD) operations extract viscous bitumen from the subsurface. During routine operations, fugitive gas can present as a surface casing vent flow (SCVF) or a gas migration (GM) in soils. Depending on regulatory thresholds, these fugitive gases can be classified as serious or non-serious. The presence of hydrogen sulfide (H2S) automatically classifies a well as serious by regulators. Thus, accurate detection and quantification is necessary to meet and exceed regulatory policies and provide the highest standards of environmental health and safety for the energy sector. This thesis investigates the impacts temperature and steam present during SAGD operations can have on the sample collection and detection of reduced sulfur species (RSS). Field results obtained from different sample techniques, handheld instruments, gas tubes and a field gas chromatograph (GC) suggested that identification of H2S and measurement of H2S concentrations are sensitive to the techniques and instruments used.
