We are seeking a Portfolio Evaluations Geologist with expertise in evaluating, ranking and strategic planning for advancing unconventional appraisal programs to full field development projects, for our Portfolio Governance Group (PGG) within the Emerging Unconventional Assets Department (EUAD).


This group of experienced geologists and geophysicists are responsible for the evaluation and maintenance of the corporate Unconventional portfolio of opportunities. The creation of a well-balanced and high-graded portfolio of exploration through development locations, to meet and replace production, is required to maintain a system in which unconventional resource opportunities are strategically ranked and fed into the short and long-range de-risking plans.


Your primary role is to manage the unconventional portfolio through technical, risk, resource and commerciality assessments integrated with strategic planning for de-risking and development.

Key Responsibilities

You will be required to perform the following:


Geological technical assessments of resource plays to ensure prospectivity.

Risk assessments to identify gaps in knowledge and quantify COS.

Resource assessments to confirm value and support reserve estimation.

You should have 15 years of experience, with at least 5-10 years in unconventional plays, including shale or tight gas, with North American experience in multiple unconventional hydrocarbon basins required. We will consider candidates with more or less experience, depending on the quality of their experience.


A background in play-based exploration for tight sand and/or shale, strategic planning for unconventional development, resource assessment and petroleum economics is essential.


Experience managing and de-risking a portfolio of tight sand or shale opportunities from exploration through development, with a strong understanding of the geological factors that determine risk in unconventional plays.


You should have knowledge in the integration of sedimentology, depositional environments, petrophysics, geomechanics, basic geophysics and basic reservoir engineering as well as experience integrating basic reservoir engineering and geology to tight and source rock reservoirs.


Previous experience working with reservoir engineers and reserve auditors to determine reserve and resource estimations is required and experience working with the production and drilling departments on well performance and optimization is preferred.
