ONGC Petro additions Limited (OPaL), a multibillion joint venture company was incorporated in 2006. OPaL is promoted by Oil and Natural Gas Corporation (ONGC) and co-promoted by GAIL and GSPC.

OPaL has set up a grass root mega Petrochemical complex at Dahej, Gujarat in PCPIR/SEZ (Petroleum, Chemicals and Petrochemicals Investment Region/Special Economic Zone). The complex's main Dual Feed Cracker Unit has the capacity to produce 1100 KTPA Ethylene, 400 KTPA Propylene and the Associated Units consists of Pyrolysis Gasoline Hydrogenation Unit, Butadiene Extraction Unit and Benzene Extraction Unit. The Polymer plants of OPaL has 2X360 KTPA of LLDPE/HDPE Swing unit, 1X340 KTPA of Dedicated HDPE and 1x340 KTPA of PP. The project commenced its production after the inauguration by Prime Minister Narendra Modi in March 2017.

The demand for polymers in India is huge and is expected to further rise with the growth in GDP. India will continue to be in deficit of Polyethylene in the foreseeable future. Moreover, this also works as a perfect downstream integration for ONGC - the key promoter who supply the required feedstock Naphtha from its Hazira, Uran and Dahej facilities, which is essential to run the plant in full capacity.

Driven by innovation, OPaL intends to build a world class petrochemical enterprise unlocking potential of its people and offer differentiated products and services.
