Manager

  • Analytical Platform Optimization: Deployed AI-assisted analytical platforms to compress manual analysis cycles. Built reusable commercial templates on industry-standard tools to establish a standardized digital workflow for cost benchmarking.
  • Capital Redeployment: Conducted a portfolio review of four legacy assets accruing recurring liabilities, recommending the cancellation of non-viable opportunities and freeing ~$450M in capital for redeployment to higher-return assets.
  • Asset Monetization: Drove the techno-commercial assessment of CO₂ storage potential across depleted reservoirs under CCUS, identifying pathways to monetize legacy assets
  • Regulatory Representation: Represented ONGC’s position before the Directorate General of Hydrocarbons (DGH) on asset evaluations, licensing decisions, and regulatory policy matters.

Senior Geologist

  • Greenfield Program Delivery: Developed the commercial business case for a $13,000M capital program in India’s eastern deepwater frontier. Coordinated cross-functional teams from scratch to secure Board approval for 3 exploration locations, leading to a successful gas discovery valued at $95M.
  • Capital Allocation & Negotiation: Secured Board approval for 5 development projects worth ~$6,500M in total lifecycle capital across two offshore assets (~100 MMToE in-place volume) through commercial evaluation and cross-functional negotiations.
  • Strategic Project De-risking: Led the cross-functional re-evaluation of a 493 sq. km offshore block in the KG Basin, identifying 7 new investment opportunities (15.75 BCM gas in-place) and building the case for a strategic exit that saved $200M.
  • Financial Risk Modeling: Designed price-sensitivity, cost-variation, and risk-scenario analyses across commodity price bands, providing quantified decision frameworks for board-level investment and divestment choices.
  • Joint Venture & Alliance Management: Served as ONGC’s core operational interface with ExxonMobil under a strategic MoU for deep-water collaboration. Conducted benchmarking discussions with Shell, and coordinated joint evaluations and data-exchange workflows with Vedanta, BP, and GSPC.

Geologist

  • Resource Monetization: Led a team in opportunity identification and resource assessment across six mature onshore fields (including a joint-venture asset), identifying ~7 MMT in-place oil and ~11 BCM in-place gas, contributing to ~1.5 MMT recoverable oil and 3 BCM recoverable gas, representing $1,200M in projected gross revenue.
  • Asset Value Recovery: Formulated and led a team to re-evaluate overlooked zones in legacy assets following regulatory changes (TNPAZD Act, 2020). Identified 3 MMT oil and 5 BCM gas within 6 months, unlocking ~$400M+ in incremental asset value.
  • Real-time Operational Control: Maintained control-room operations and provided real-time operational support during high-pressure drilling campaigns, interpreting live data to guide technical decisions during pandemic-related staffing constraints.
  • Resource & Supply Chain Allocation: Coordinated procurement planning and inter-asset resource allocation across simultaneous exploration campaigns, ensuring project timelines aligned with regulatory deadlines.
  • Investment Appraisal: Assessed viability and risk across 30+ investment opportunities through data-driven analysis, supporting risk-weighted capital prioritization across competing exploration proposals.
