MOSCOW--Russian state oil giant OAO Rosneft (ROSN.MZ) Friday said it had signed a deal to acquire a 16.7% stake in the PCK Raffinerie GmbH oil refinery from Total SA (TOT), which is located in Schwedt, Germany.

Rosneft owns 50% of Ruhr Oel GmbH, which in turn owns 37.5% of the plant, giving the two companies control of almost 55% of the refinery's ownership, Rosneft said. Royal Dutch Shell PLC (RDSA.LN) owns 37.5% and ENI SpA (ENI.MI) owns 8.3%.

Rosneft Chief Executive Igor Sechin signed the deal Friday with Total CEO Patrick Pouyanne. Rosneft said in a statement that the deal represents "a deepening of the energy partnership between Russia and Europe."

"As for Rosneft, this deal means a strengthening of its position in one of Europe's most efficient and effective refineries and an opportunity to serve the end-customers in its most important market," Mr. Sechin was quoted as saying in the statement.

Rosneft, through Ruhr Oel GmbH, owns stakes in four other German refineries.
