Sources privy to the development said the Saudi oil minister will visit Mumbai for the wedding and will also make a brief stopover in the national capital to have a conversation with Oil Minister Dharmendra Pradhan and other industry leaders.
Al-Falih, who has known Ambani for over a decade now, had previously travelled to Udaipur in December last year to attend the pre-wedding festivities of Ambani's daughter Isha's marriage with industrialist Ajay Piramal's son Anand.
Akash and Shloka's wedding will take place at the newly built Jio World Centre in Bandra Kurla Complex in Mumbai. The wedding festivities kickstarted on February 23 with a grand bash in St. Moritz, Switzerland.
The couple got engaged in June 2018 and celebrated the occasion with a string of lavish parties in Mumbai.
When he last visited the Ambanis in December 2018, the Saudi oil minister had tweeted that the world's largest oil exporter Saudi Arabia and Ambani-run Reliance Industries are discussing joint investments in petrochemicals, refinery and communications projects.
Reliance operates two refineries at Jamnagar with a total capacity of 68.2 million tonnes per annum.
Reliance plans to expand its only-for-exports SEZ refining capacity to just over 41 million tonnes from the current 35.2 million tonnes but does not have any plans to set up a new refinery in the country.
It is presently focused on expanding petrochemicals and telecom business, industry sources said.
Saudi Arabia, on the other hand, is keen to get a foothold in the world's fastest-growing fuel market so as to get a captive customer for the crude oil it produces.
Saudi Aramco, the world's biggest oil company, and its partner Abu Dhabi National Oil Co (ADNOC) have picked up 50 per cent stake in a planned $44-billion refinery in Maharashtra but the project is facing problems in land acquisition.
Aramco and ADNOC will together hold 50 per cent stake in the 60 million tonnes per annum (MTPA) refinery and adjacent 18 MTPA petrochemical complex planned to be built at Ratnagiri district of Maharashtra by 2025.
The two will supply half of the crude oil required for processing at the refinery.
Like other major producers, the two are looking to lock in customers in the world's third-largest oil consumer through the investment. Kuwait too is looking to invest in projects in return for getting an assured offtake of their crude oil.
India has a refining capacity of 247.6 million tonnes, which exceeds the demand of 206.2 million tonnes.
According to the International Energy Agency (IEA), this demand is expected to reach 458 million tonnes by 2040.
