Job description

Role: Senior Reservoir Engineer

Overview

The Senior Reservoir Engineer will support classical and advanced reservoir engineering activities across the full asset lifecycle — from PVT/SCAL data analysis, dynamic simulation, and field development planning to concept evaluation and pilot studies for enhanced recovery processes. The role involves close collaboration with client representatives, service delivery teams, and multi‑disciplinary subsurface professionals (geophysicists, geologists, Petrophysicist, geomechanics) to build integrated full field models to drive field development decisions. Experience with thermal and reactive process simulation (e.g., in‑situ combustion, coupled multi‑physics systems) is a strong plus.

Key Responsibilities

• Perform classical reservoir engineering studies, including PVT and fluid modelling, and SCAL data interpretation and validation
• Develop, run, and interpret dynamic/numerical simulation models to forecast oil and gas production
• Support field development planning, EOR studies, and recovery optimization, including new well locations and enhanced recovery methods
• Collaborate with multi‑disciplinary teams and other domain PTEs to align on requirements, define solutions, and ensure consistency across subsurface workflows
• Consult with relevant subject matter experts to optimize technical design
• Model in‑situ combustion, heat transfer, and thermal/reactive flow behavior in porous media
• Implement coupled workflows incorporating thermal, flow, geomechanical, and chemical interactions, and support scale‑up from pilot‑scale to full‑field development cases
• Contribute to scale‑up from pilot‑scale models to full‑field development cases

Location of assignment: Navi Mumbai

Qualifications & Experience details

• Degree in Petroleum Engineering or related discipline
• Demonstrable ability in planning, organizing, and executing studies/projects
• Strong general understanding of reservoir simulation engineering activities across the full asset lifecycle
• 10+ years of experience in reservoir simulation, with focus on compositional and thermal processes
• Experience with SLB simulators (Eclipse, INTERSECT) and coupled modeling with Visage
• Exposure to in‑situ combustion, heavy oil recovery, gasification, or similar thermal processes
• Understanding of multi‑physics coupling (thermal‑flow‑geomechanics‑chemical) is desirable

Educational qualifications and Experience

• Bachelor’s/ master’s degree in petroleum engineering or related discipine with working experience of 10+ years as Reservoir Engineering and simulation, with E&P/ Service industry
