"Shell is honored to have been selected by ADNOC to develop the Bab sour gas reservoirs," Shell Chief Executive Officer Peter Voser said in a statement. "We value our long and successful partnership with ADNOC and look forward to continuing to play a role in helping the United Arab Emirates meet its energy needs."
Shell will have a 40 percent stake in a joint venture that has a 30-year term. Natural gas from the Bab field will service the Emirati economy.
Shell's announcement coincided with a visit to the United Arab Emirates by British Prime Minister David Cameron. French President Francois Hollande courted Emirati investors during his visit in January.
Cameron was quoted by the BBC as saying Shell's deal is "the largest secured by a British company in the UAE in recent years."
The Bab project is said to be valued at around $10 billion.
