About the job

Job Title: Reservoir Engineer I

Entity: OER

Reports To: Senior Reservoir Engineer

Purpose (Summarize briefly the major function and purpose of the position)

Proper management of producing reservoirs.

To provide reservoir engineering input into projects from initial opportunity identification to cessation of production, including selection and definition of development plans, ensuring the integration of subsurface and surface parameters in dynamic reservoir analysis, maximizing recovery efficiencies and optimizing production potential.

Ensuring value protection for organization through critical review of operating partner’s reservoir engineering inputs and assumptions

Supervisory Responsibility (Indicate positions that report directly to this position.
