At Murphy Oil Corporation, we believe the rich experiences and backgrounds of our employees strengthen our Company, create a productive workforce, and drive our success. We encourage you to apply for the positions for which you meet the qualifications.

The Sr Reservoir Engineer should be a self-starter who is comfortable contributing in a fast-paced, multidisciplinary environment. The role requires demonstrated reservoir engineering experience supporting deepwater field development, infill drilling evaluation, production performance management, reserves assessment and economic analysis.

Supporting maturation of drilling opportunities is a major part of the role and requires close collaboration with geoscientists, production engineering, drilling, flow assurance, regulatory and commercial teams to optimize development options while balancing risks and uncertainties within a fit-for-purpose value assurance framework.

The Sr Reservoir Engineer will integrate reservoir engineering analysis, simulation, production data, pressure transient analysis, PVT data and economic evaluation to support development planning, portfolio prioritization, depletion strategy, well planning and opportunity progression. The role will document results and develop concise supporting presentations to clearly communicate recommendations to management, partners and regulatory authorities.

This role will work in our Houston Corporate office and may work up to two (2) days a week remote.

• Develop and evaluate deepwater field development plans, infill drilling opportunities, workovers and stimulation options using integrated reservoir, production, geoscience and economic analysis.
• Monitor well and reservoir performance versus expectations; identify drivers of variance and recommend actions to protect base production and improve asset value.
• Build, maintain and calibrate analytical and numerical reservoir models, including material balance, pressure transient analysis, PVT analysis and reservoir simulation.
• Support pre-drill planning and well delivery by integrating uncertainty, reservoir risk, expected performance, reserves/resource impacts and economic outcomes into recommendations.
• Partner with geoscience, production engineering, drilling, flow assurance, regulatory, commercial and partners to align technical work with business priorities and execution plans.
• Support reserves, forecasting and portfolio management activities by tracking performance against booked reserves, documenting changes and framing development options for decision-making.
• Prepare clear technical documentation and concise presentations that communicate assumptions, risks, recommendations and next steps to management, partners and regulatory authorities.
• Promote quality data, transparent workflows and fit-for-purpose improvements to reservoir engineering tools, processes and integrated subsurface evaluations.

• Bachelor’s degree in Engineering; degree in Petroleum Engineering or related engineering discipline preferred.
• Minimum 7 years’ experience in Reservoir Engineering; deepwater Gulf of America experience preferred.
• Demonstrated experience with field development studies and/or infill drilling evaluations, including uncertainty analysis and economic assessment.
• Experience with reservoir simulation, network modeling, pressure transient analysis, PVT analysis, production forecasting and reserves evaluation.
• Demonstrated experience with tNavigator/Eclipse, Kappa/Saphir, PVT/PVTsim, Val Nav, MBal, Prosper, Power BI or similar software packages.
• Experience working with multidisciplinary teams across geoscience, drilling, production, flow assurance, regulatory and commercial functions.
• Ability to work on multiple projects simultaneously in a fast-paced environment is essential.
• Strong verbal and written communication skills.

• Background or direct experience in Production Engineering, including well performance surveillance, well potential, production constraints, workover/stimulation evaluation and root-cause analysis.
• Experi…
