Project: The influence of diagenetic process on the petrophysical properties and geochemical composition of the Montney Formation in Alberta and northeastern British Columbia.
Whilst diagenetic processes affecting sandstone and shale reservoirs are fairly well understood, these mechanisms have never been investigated before in siltstone reservoirs, such as the Montney Formation. This formation is a siltstone gas reservoir with vast estimated reserves, found in the Western Canadian Sedimentary Basin. Considering the significant influence that diagenesis has on reservoir characteristics such as porosity, permeability and mechanical properties, it is important to accurately describe those processes and constrain their effects on reservoir quality.
In my study I will develop better reservoir models through new insights into chronostratgraphic correlations, and identifying sediment sources and depositional systems through geochemical tracers. I will utilize high resolution microscopy imaging techniques, ICP-MS analysis of major, minor and trace elements, mercury porosimetry and pulse decay permeability measurements of core samples. This will allow me to characterize the mineralogical composition, the diagenetic phases and the paragenetic sequence of the Montney Formation, and interpret the depositional environment and climatic conditions.
