SINGAPORE/NEW DELHI, Nov 14 (Reuters) - India's Bharat

Petroleum Corp has bought about 3.7 million barrels

crude oil from West Africa, United States and the Middle East

via spot purchases this week to replace oil from Russia, trade

sources said.

The refiner bought one million barrels of Angola's Agogo

crude from Eni for the first time and one million

barrels of U.S. Mars crude from Shell, the people said.

It also purchased 700,000 barrels of Kuwaiti Ratawi crude

from Chevron ( CVX ) and one million barrels of Abu Dhabi's

Upper Zakum crude from Trafigura, they added.

The spot buying comes as Indian refiners look for

alternatives after pausing Russian oil imports last month due to

Western sanctions on Russia's top oil producers.
