ONGC Tender Process

ONGC's tender process is the competitive procurement system through which Oil and Natural Gas Corporation, India's largest E&P company, awards contracts for exploration drilling, well services, offshore platform construction, seismic surveys, pipeline materials, and support services through its dedicated e-tendering portal with a structured contractor/vendor registration system.

What is ONGC's Tender Process?

ONGC is a Maharatna CPSE under MoPNG with an annual capex of Rs 35,000+ crore. Its procurement spans upstream oil and gas activities across onshore and offshore assets in 16 basins nationwide.

ONGC's e-procurement portal (etender.ongc.co.in) handles the complete procurement lifecycle. Vendor/contractor registration is the first step, ONGC maintains approved contractor lists for different categories (drilling services, civil works, offshore fabrication, equipment supply) with distinct qualification criteria.

Key procurement categories:

• Drilling: Drilling rigs (onshore and offshore jack-up/semi-sub), drilling mud chemicals and services, cementing, wireline logging, directional drilling
• Well services: Completion equipment, workover services, production testing, well stimulation
• Seismic: 2D/3D seismic acquisition and processing services
• Offshore: Platform construction and installation (EPCI contracts), FPSO/FSO, offshore pipeline installation (marine spread)
• Onshore infrastructure: Crude oil/gas processing facilities, gathering pipelines, trunk pipelines
• Materials: API 5L pipes, API 6A wellhead equipment, API 16D control systems, valves, flanges
• Services: Engineering consultancy, project management, inspection services

ONGC uses two-stage procurement for large EPCI (Engineering, Procurement, Construction, Installation) contracts for offshore platforms. First stage evaluates technical capability; second stage opens price bids from qualified vendors.

Why ONGC's Tender Process matters for Indian government suppliers

ONGC is the single largest buyer in India's oil and gas supply chain. Approved vendor status with ONGC is a strategic asset, once registered, vendors receive invitations for tenders in their approved categories for the registration period. ONGC's payments are reliable (central PSU), making it a preferred client for large equipment and service companies.

Example

ONGC issues an EPCI tender for a new 8-well unmanned wellhead platform in the Western Offshore (Arabian Sea), including topsides engineering, procurement, fabrication in India, and offshore installation by marine spread, estimated Rs 950 crore. The NIT requires previous experience of two comparable offshore platform EPCI projects. Two qualified offshore contractors bid; the L1 at Rs 870 crore wins.

Frequently Asked Questions

How do I register as an ONGC vendor?

Vendor registration is done through ONGC's Vendor Registration System. Vendors submit company profile, balance sheets (three years), technical experience, equipment inventory, HSE certifications (ISO 14001, ISO 45001), and applicable API/IS certifications for the product/service category. ONGC's materials/procurement department evaluates and approves registrations.

What API certifications are required for ONGC material supply?

Oil country tubular goods (OCTG), wellhead equipment, valves, and drilling equipment must carry relevant API monograms (API 5L, API 6A, API 16D, API 7-1 etc.). ONGC's approved vendor list for these materials includes only API monogram holders. Non-monogram vendors cannot bid for critical oilfield materials.

Does ONGC use CPPP for its tenders?

ONGC uses its dedicated portal (etender.ongc.co.in) as the primary system. NIT abstracts are published on CPPP and ONGC's corporate website as secondary channels. Bid submission and all procurement activities are on ONGC's own portal.

What is ONGC's payment record for contractors?

ONGC is generally a reliable payer with payment terms of 30-45 days from invoice submission. Large offshore projects sometimes experience payment delays during government budget cycles, but ONGC's PSU status and central government backing make it a preferred client from a credit risk perspective.
