Senior Reservoir Engineer Mature Assets

Senior Reservoir Engineer

Role Summary

Provides senior reservoir engineering input to asset screening focusing on recoverable volumes, production forecasts, recovery mechanisms, and reservoir-related risks. Supports the Team Lead by translating subsurface uncertainty into recovery and development implications suitable for economic evaluation.

Key Responsibilities

• Estimating STOIIP/GIIP and recoverable volumes using volumetrics, analogs, material balance, and fit‑for‑purpose models.
• Defining reservoir‑related risks and uncertainties for inclusion in the asset risk register (connectivity drive mechanism, sweep, injectivity, pressure support).
• Developing screening‑level production profiles (P90/P50/P10) consistent with reservoir behavior and facilities constraints.
• Screening well count, spacing, depletion strategy, and EOR potential at a concept level and translating that into impacted service lines with...
