ADNOC Gas plc, the world-class integrated natural gas company, and its subsidiaries have signed a sales and purchase agreement (SPA) with the major Indian state-owned oil and gas company, Hindustan Petroleum Corporation Limited (HPCL), valued between $2.5 and $3 billion over 10 years.

ADNOC Gas has converted a previously signed Heads of Agreement (HoA) with Hindustan Petroleum Corporation Limited (HPCL) into a long-term sales SPA. The deal covers the export of 0.5 million tons per year (mtpa) of liquefied natural gas (LNG) from ADNOC Gas’ Das Island facility, a strategic asset with a 6 million tonnes per annum (mtpa) capacity that has successfully delivered over 3,500 cargoes to global markets.

HoA is a preliminary, non-binding document that outlines the main terms and intentions of a proposed deal or partnership. It serves as a framework for negotiating a detailed, legally binding contract, such as a sales and purchase agreement (SPA).

The agreement was finalised during a high-profile state visit to India by UAE President Sheikh Mohamed bin Zayed Al Nahyan, where he met with Indian Prime Minister Narendra Modi to deepen bilateral energy cooperation. This milestone brings the total value of LNG contracts signed by ADNOC Gas since its inception to over $20 billion.

The deal strengthens the UAE-India energy partnership and secures ADNOC Gas’ role as a leading supplier to Asia. India is now the UAE’s top LNG customer. With this agreement, ADNOC Gas has committed 3.2 mtpa to Indian companies—a major part of the 15.6 mtpa it plans to produce by 2029.

Over the past three years, the company has signed multiple long-term LNG contracts ranging from 0.4 to 1.2 mtpa, with terms of up to 14 years, cementing its role as a leading supplier of reliable, lower-carbon LNG to Asia’s fast-growing energy markets.
