Project: Petroleum System Analysis of the Triassic Doig Formation, Western Canada Sedimentary Basin
The objective of this project is to determine the unconventional hydrocarbon potential of the Doig Formation through a petroleum system analysis. The study will assess the volume, distribution of hydrocarbons generated and retained; the scope also includes mapping the spatial and stratigraphic variability of reservoir and source-rock properties, such as storage capacity, organic matter type and abundance, matrix permeability and elastic properties, as well as defining the geological controls on these properties. The project is divided into three inter-related sections. The first concerns the modeling of the Doig petroleum system on a basin scale with focus on thermogenic hydrocarbon generation and retention. The model will incorporate structural, lithological, geochemical and burial history data in an integrating basin modeling software platform.
The second is the evaluation of the source-rock properties of the Doig Formation and involves quantification and mapping of organic matter abundance and type, as well as maturity levels across the basin. The third section’s theme is the characterization of the reservoir potential of the Doig Formation in terms of storage capacity, producibility and response to hydraulic stimulation, by investigating and drawing relationships between lithological, geomechanical, reservoir and geochemical properties. Finding correlations between lithofacies, organic facies and reservoir facies will aid the determination of geologic controls on organic richness, petrophysical and geomechanical properties, enhancing the prediction capability for “sweet spots”. The basin model will serve as an integration platform between the pore and regional scales. It will be informed by the results from the analytical work, and it will constrain the timing of generation and migration of hydrocarbons in the Doig, as well as provide an estimate of the volume and main phase of hydrocarbon retained as opposed to expelled.
