Job description

Job Purpose

• Leads and executes advanced reservoir engineering activities, including simulation studies, reserves estimation, well surveillance, and field development strategies.
• Supports production optimization through reservoir modeling and simulation, working closely with multidisciplinary teams to improve ultimate recovery and guide operational decisions.
• Undertakes and supervises studies and special projects, including reservoir simulation studies and integrated development plans for improving methods of exploration and production of crude oil and related products.

Key Accountabilities

• Analyzes geological and petrophysical data to characterize reservoir properties, including porosity, permeability, and fluid behavior.
• Develops accurate reservoir models using reservoir simulation software to predict reservoir performance over time.
• Incorporates well data, pressure data, and production history to refine reservoir models.
• Estimates hydrocarbon reserves using various methods, including material balance calculations, decline curve analysis, and numerical simulation.
• Prepares reserves reports compliant with industry standards and regulatory requirements.
• Collaborate with regulatory agencies and internal teams to ensure accurate and transparent reporting.
• Support Ministry and joint venture reporting, and present technical findings to management.
• Develops and implements strategies to optimize production and recovery from reservoirs.
• Recommends well intervention techniques, such as workovers or stimulations, to enhance well productivity.
• Analyzes well performance and propose changes to well operations based on reservoir dynamics.
• Evaluates and recommends appropriate enhanced oil recovery methods, such as waterflooding, gas injection, or chemical treatments.
• Conducts feasibility studies and simulations to assess the potential of EOR techniques.
• Monitors and assesses the effectiveness of implemented EOR projects.
• Analyzes pressure data to understand reservoir dynamics and behavior.
• Designs and implements pressure maintenance strategies to maintain reservoir pressure and maximize recovery.
• Interprets pressure transient tests and pressure buildup data to refine reservoir models.
• Strictly follows established environmental, health, safety and quality policies and procedures to guarantee employee safety, legislative compliance, delivery of high-quality products/services, and a responsible environmental attitude.
• Undertakes accountabilities in the operational excellence process as set out in the schedule of responsibilities.
• Contributes to the processes of continuous improvement for the area assigned.
• Performs any other relevant task as directed by Superintendent Petroleum Engineering & Development.
