NEW DELHI, July 19 (Reuters) - India ONGC Videsh has

signed a $60 million deal with Norwegian energy giant Equinor ( EQNR )

to raise its stake in the offshore Azeri Chirag

Gunashil (ACG) oil field in the Caspian sea and linked pipeline,

the Indian company said on Friday.

OVL, the overseas investment arm of India's top explorer,

will buy a 0.615% stake in the oilfield and a 0.737% share in

the Baku Tbilisi Ceyhan (BTC) pipeline from Equinor ( EQNR ), it said in

a stock exchange filing.

"The acquisitions are expected to be completed in the

upcoming months," it said.

ONGC Videsh has a 2.31% interest in the ACG field and a

2.36% shareholding in the BTC pipeline.

The BP-operated ACG field is the largest oilfield in the

Azerbaijan sector of the Caspian basin and the BTC pipeline is

used to transfer crude oil to the Turkish Mediterranean coast.

The other partners in the field are Azerbaijan state energy

company SOCAR, Hungarian energy firm MOL, Japan's Inpex ( IPXHF )

and Itochu, and Turkey's TPAO.
