Regional Stratigraphic architecture and reservoir sedimentology of Basal Belly River shoreline units – in partnership with Moslow Geoscience Consulting
for Lotus Creek Energy
In this work, we reconstructed the stratigraphic architecture and map eight Basal Belly River (BBR) shoreline sandstone units over 230 townships (approx. 21,400 km2) in south-central Alberta. Based on these extensive regional correlations of over 18,000 well, and gross sandstone mapping complemented with detailed sedimentological core descriptions from 21 wells in the Wilson Creek area, we interpreted the depositional history and built a sequence stratigraphic model for these BBR shoreline units.

Basin-scale high resolution stratigraphic correlation of the Montney Formation – in partnership with Moslow Geoscience Consulting
for Vermilion Energy
A well defined along-strike depositional architecture laid the foundation for the stratigraphic log correlation of over 5,400 wells across Montney sub-basins, calibrated with available core descriptions and conodont biostratigraphy. This updated stratigraphic model can help better predict spatial variations of facies and reservoir properties both at local and regional scales and provides a robust framework to compare production performances within and between operators’ assets.

Fluid and Excess Pressure mapping in Peace River Arch area of the unconventional Montney Play – in partnership with Enlighten Geoscience and Agat Laboratories
for Vermilion Energy
This project combined high-resolution stratigraphy (from previous projects with Vermilion Energy) with fluid geochemistry, hydrodynamic mapping and PVT data to better understand im-situ liquids richness and risk for potential production fractionation in different zones of the Montney unconventional play.

Fluid and Excess Pressure mapping in Karr-Kakwa area of the unconventional Montney Play – in partnership with Enlighten Geoscience and Agat Laboratories
for Archer Exploration
This study combining geochemical mapping, hydrodynamic mapping and PVT analysis served two main objectives: (1) better predict in-situ-fluid distribution linked to thermal maturity and secondary gas/condensate migrations and (2) understand the spatial variations of Excess Pressure (difference between reservoir pressure and fluid saturation pressure) and their potential impact on produced GOR and liquids recovery.

Fluid and Excess Pressure mapping in the Northern Montney unconventional Play – in partnership with Enlighten Geoscience and Agat Laboratories
for Tourmaline Oil
In-situ fluid composition not only control liquids richness in the reservoir but also impacts saturation pressure and risk of phase separation often leading to dramatic increase of GOR during early production. In this project, we combined in-situ GOR/CGR (using geochemical proxies and early flow test data) and reservoir pressure data to map Excess Pressure in different producing zones of the Northern Montney play. The Excess Pressure is the difference between the reservoir pressure and the estimated in-situ fluid saturation pressure. This provides our client with a way to highlight areas with higher potential for liquids recovery or higher risk for production fractionation.
