Work History
Senior Production Engineer
Essar Oil and Gas Exploration & Production Limited
11.2022 - Current
- Led production engineering team for one region in CBM field (100+ wells), overseeing well performance, intervention planning, and artificial lift optimization, resulting in 15% improvement in average field output.
- Implemented well dewatering and ramp-up strategies that increased gas production across underperforming clusters by 10% within 6 months.
- Selected and deployed artificial lift systems (primarily PCPs) based on reservoir and well performance analytics, improving run life and reducing failures.
- Utilized SCADA-based real-time surveillance to cut well downtime by 30%, enabling faster decision-making and intervention.
- Executed surfactant and acid stimulation campaigns (via ISAP tool and foam diversion), enhancing productivity in low-pressure wells by up to 30%.
- Conducted failure analysis and executed scale and corrosion mitigation plans, extending equipment life and minimizing production losses.
- Collaborated with cross-functional teams to select refrac candidates and identify permeability impairment, contributing to long-term recovery planning.
- Prepared technical scopes, evaluated vendor proposals, and led chemical procurement and intervention job planning—streamlining project execution.
- Delivered monthly/yearly production forecasts and performance dashboards for senior management, tracking field KPIs and intervention outcomes.
Production Engineer
Essar Oil and Gas Exploration & Production Limited
04.2015 - 10.2022
- Managed production operations across mature oil field, focusing on well optimization, water cut control, and asset integrity to sustain base production levels.
- Planned and designed well intervention and stimulation campaigns including acid jobs, sand cleanouts, zonal isolation, and HOC jobs, resulting in aggregate incremental oil recovery of 12–15% across targeted wells.
- Performed well performance diagnostics and reservoir analysis to identify causes of water production and implemented zonal shut-off and re-perforation techniques to reduce water cut by up to 40% in critical wells.
- Developed production surveillance workflows, supported by nodal analysis, to identify production bottlenecks and prioritize candidate wells for optimization.
- Participated in HAZOP studies, shutdown planning, and regular HSE audits, contributing to a zero LTI record over multiple field campaigns.
- Generated monthly production forecasts, field operating expense (OPEX) reports, and performance scorecards for senior management review.
Drilling & Workover Engineer
Essar Oil and Gas Exploration & Production Limited
08.2011 - 03.2015
- Supervised rig operations for both new drilling and workover campaigns in onshore fields.
- Prepared well programs including casing design, BHA selection, and mud planning.
- Monitored well bore stability, well control events, and successfully executed complex fishing and sidetracking jobs.
- Coordinated with geology and logging teams during drilling and completion phases.
- Maintained high safety standards and ensured cost-effective execution.
