Data Scientist (Contract) — Exploration Analytics

About this Data Scientist role at Oil and Natural Gas Corporation (ONGC)

ONGC's Centre of Excellence in Data Analytics is hiring Data Scientists for a 3-year fixed-term contract in Mumbai. This is your chance to work on India's largest energy company's most critical challenges—using machine learning and data science to optimize oil and gas exploration and production. The role is on-site in Mumbai with field travel, directly applying advanced analytics to real-world petroleum problems.

What you'll do

• Build and deploy machine learning models using Python, scikit-learn, and gradient boosting algorithms to solve exploration and production analytics problems
• Analyze seismic data and well-log data—the core technical foundation of petroleum engineering—to extract insights for field optimization
• Develop deep learning solutions for complex geological pattern recognition and predictive modeling
• Collaborate with ONGC's geophysics and petroleum engineering teams to translate data science findings into actionable business decisions
• Work on contract-based exploration analytics projects with direct application—no competitive exam required

Who should apply

You're a mid-level Data Scientist with 3–7 years of hands-on experience in machine learning. ONGC requires an M.Tech or MS degree in Data Science, Petroleum Engineering, Geophysics, or a related field with formal ML training. You should have solid Python skills, understand gradient boosting and deep learning frameworks, and ideally have curiosity about domain applications like seismic or well-log analysis. Freshers or junior candidates without the required experience need not apply—ONGC is looking for someone ready to contribute immediately on complex analytics projects.
