Support Activities
Firm Infrastructure
ONGC's firm infrastructure is built on a centralized, state-owned governance model, with the Government of India holding 58.89% equity in FY2025. This helps align approvals, safety, compliance, and capital spending across onshore fields, offshore platforms, and overseas assets. For a business handling large upstream projects, tight control keeps execution and risk management disciplined.
Human Resource Management
In FY2025, ONGC relied on a large technical workforce of about 25,000 employees, led by engineers, geoscientists, drilling specialists, and field crews, to run complex onshore and offshore work. Training, job rotation, and retention matter because they protect safety, move know-how across rigs and basins, and keep execution steady in remote sites. For a high-risk operator, strong human resource management is a direct driver of uptime, incident control, and project delivery.
Technology Development
ONGC uses seismic imaging, reservoir modeling, enhanced recovery methods, and digital field monitoring to squeeze more output from mature fields. In FY25, this mattered more because India still imported about 88% of its crude oil, so every incremental barrel from ONGC cuts import pressure. Better subsurface data and drilling control can extend field life, lift recovery from mature reservoirs, and lower unit lifting costs, especially where decline rates often run 5% to 15% a year without intervention.
Procurement
In FY25, ONGC's procurement covered rigs, well services, pipes, chemicals, subsea gear, and engineering work through tendering and vendor control. This matters because upstream oil and gas projects are capital-heavy, so tight buying terms help ONGC protect margins, secure critical inputs, and avoid delay costs.
ONGC's Hidden Engine: State Backing, 25,000 Staff, and 88% Crude Dependence
ONGC's support activities in FY2025 were anchored by state control, a 25,000-strong technical workforce, and heavy use of seismic, reservoir, and digital monitoring tools. It spent across rigs, well services, pipes, chemicals, and subsea gear to keep offshore and onshore projects moving. These functions mattered because India still imported about 88% of crude, so every uptime gain had direct value.
| FY2025 support metric | Value |
|---|---|
| Government stake | 58.89% |
| Employees | About 25,000 |
| India crude import dependence | About 88% |

Primary Activities
Inbound Logistics
ONGC's inbound logistics moves drilling consumables, pipes, chemicals, and equipment to onshore and offshore sites, and timing matters because rig downtime can cost more than US$100,000 a day in FY25 oilfield markets.
By staging inputs near wells and offshore bases, ONGC cuts non-productive time and keeps exploration and workover crews supplied.
For a scale operator with FY25 production spread across 26 sedimentary basins, even small supply delays can hit output and cash flow.
Operations
ONGC's operations span seismic surveys, exploration, drilling, field development, crude output, and gas output. FY25 crude oil production was about 18.5 MMT, and natural gas output was about 20.1 BCM.
This is the core value-creation engine, so reservoir quality, recovery rates, downtime, and project execution drive results. Better well uptime and faster field development lift output and cash flow.
In a capital-heavy upstream business, small gains in drilling success or recovery can move annual volumes by millions of barrels.
Outbound Logistics
ONGC moves crude oil and natural gas through pipelines, terminals, tankers, and processing networks. In FY2025, that scale made evacuation speed a direct driver of realizations, cash flow, and lower bottlenecks. Reliable dispatch also keeps supply steady for refineries, gas buyers, and industrial customers.
Marketing and Sales
ONGC sells crude oil, natural gas, and related output to refiners, fertilizer units, power plants, city gas players, and other industrial users. In FY25, this primary activity depended on contract terms, pricing discipline, and steady delivery, because these set how much revenue ONGC can actually realize from production.
Stronger offtake access and reliable supply matter most when buyers run on tight feedstock schedules. One clean sale lost or delayed can hit both cash flow and market trust.
Service
ONGC's service activity focuses on asset maintenance, reservoir management, well intervention, and environmental remediation, which keep aging fields running with fewer shutdowns. In FY2025, this technical work helped protect output from mature Indian basins and supported steady supply to refiners and buyers. It also cuts leak and failure risk, which matters because service quality shapes long-term field life and future cash flow.
ONGC FY25: Strong Output Across 26 Basins
ONGC's primary activities in FY25 were exploration and drilling, crude oil and gas production, evacuation, and sales. It produced about 18.5 MMT of crude oil and 20.1 BCM of natural gas, so uptime and recovery rates directly shaped cash flow.
Fast logistics and steady field operations reduced non-productive time across 26 sedimentary basins.
| Activity | FY25 data |
|---|---|
| Crude output | 18.5 MMT |
| Gas output | 20.1 BCM |
| Basin coverage | 26 |

Frequently Asked Questions
ONGC's core value chain is driven by upstream exploration, development, and production. The model is organized around 4 support activities and 5 primary activities, but the real earnings leverage comes from lifting volumes, improving recovery in mature fields, and keeping evacuation reliable across India and overseas assets within its broader 3 business areas: upstream, downstream, and power-renewables.
