What you will play in our team
Lead Geoscientist – Oil Sands Stratigraphy and Reservoir Characterization

Drive mine performance by unlocking the geologic complexity of the McMurray Formation through expert strati graphic interpretation.

We are seeking a highly skilled Oil Sands Geoscientist with deep strati graphic expertise to join our subsurface team. This is a high-impact role at the core of our asset development strategy, where you will shape our understanding of complex oil sands reservoirs and directly influence how they are developed and optimized.

As a key contributor, you will lead advanced reservoir characterization efforts, building and applying robust strati graphic frameworks to unlock value within the McMurray Formation. You will integrate geological, geophysical, and engineering datasets to deliver insight-driven interpretations that underpin geological models, guide drilling programs, improve reservoir and orebody understanding, and optimize development plans.

This role combines technical excellence with strategic influence. You will translate complex subsurface data into clear, actionable recommendations, ensuring high-quality geological interpretations underpin critical business decisions.

Primary Job Functions
Technical Leadership & Stakeholder Engagement
Serve as a senior geological resource and technical leader, providing mentorship, guidance, and quality control to geoscientists and junior staff. Champion rigorous strati graphic interpretation standards and ensure consistency in geological models and subsurface frameworks across the asset. Engage with internal stakeholders—including reservoir engineering, mine planning, and operations teams—to communicate subsurface uncertainty and provide actionable recommendations that influence development.

Strati graphic Interpretation & Depositional Framework Development
Lead detailed strati graphic interpretation and regional-to-local scale correlation within oil sands deposits. Develop robust sequence strati graphic frameworks that integrate core, well log, seismic, and outcrop analog data into coherent depositional models. Interpret sedimentological features, facies architecture, and stacking patterns to define reservoir geometry, continuity, and heterogeneity. Ensure interpretations are geologically sound, scalable, and aligned with development and mining strategies.

Develop, maintain, and continuously refine high-resolution 3D geological models to support reservoir development, mine planning, and in situ operations. Translate geological interpretations into geomodels that accurately represent facies distributions, net-to-gross variability, and reservoir quality trends. Identify and quantify reservoir heterogeneity, including baffles, barriers, and connectivity impacts, ensuring models effectively support simulation, resource estimation, and operational planning.

Integration of Subsurface Data
Drive multi-disciplinary data integration by combining core descriptions, wireline logs, seismic interpretations, and analog datasets into unified geological frameworks. Ensure consistency between datasets and resolve discrepancies to build defensible subsurface interpretations. Leverage data integration to enhance confidence in reservoir characterization and reduce uncertainty in development planning.

Resource Evaluation & Reserves Support
Provide geological input into resource assessments and reserves estimations, ensuring compliance with industry reporting standards. Support volumetric calculations, classification of resources, and evaluation of recoverability. Assess geological uncertainty and communicate its impact on resource potential, development scenarios, and economic outcomes.

Drilling Support & Subsurface Execution
Support drilling programs through well planning, placement recommendations, and real-time geological interpretation. Integrate LWD/MWD and wireline data during drilling operations to refine strati graphic understanding and optimize well trajectories. Provide timely, operationally relevant geological guidance to maximize…
