Main tasks and responsibilities
- Provide expert reservoir engineering input to support investment valuations, asset acquisitions, divestments, and farm-in/farm-out evaluations within the Commercial function.
- Lead subsurface technical assessments including reserves and resources estimation, production forecasting, and field performance analysis in support of commercial transactions and portfolio reviews.
- Conduct and quality-assure reservoir simulation studies, material balance analyses, and decline curve analyses to underpin volumetric and economic evaluations.
- Provide independent technical review and challenge of subsurface assumptions used in investment cases, business development notes, and project initiation notes.
- Support due diligence processes for upstream opportunities, including data room visits and technical assessment of third-party assets.
- Collaborate with the Economics & Planning function to integrate subsurface uncertainty ranges into economic models, sensitivity analyses, and risk-weighted valuations.
- Develop and maintain reservoir engineering standards, tools, and workflows relevant to the Commercial function's investment evaluation process.
- Provide technical guidance and mentoring to less experienced engineers within the team.
- Represent OQEP in technical forums, joint venture meetings, and partner discussions on reservoir engineering matters as required.
- Liaise with operated and non-operated asset teams to gather subsurface data and validate technical assumptions used in commercial evaluations.
- Contribute to the preparation of investment proposals, executive summaries, and board-level presentations related to upstream opportunities.
- Ensure all technical evaluations and reports are documented in accordance with company Data Management Standards.
- Support the continuous improvement of valuation methodologies and best practices within the Investment Valuations & Strategy function.
- Actively participate in and promote OQEP's HSE culture, ensuring all work is carried out in accordance with HSE policies, procedures, and targets.
- Perform other related duties as assigned.
