Argentina’s oil company Pluspetrol launched a tender to sell three 300,000 barrel cargoes of naphtha for delivery from February 25 to April 5 at Berth port in Peru, an invitation seen by Reuters on Wednesday says.

Pluspetrol and its partners in the blocks 88 and 56 in the Peruvian Camisea field tender to sell most of its production on the open market. In recent weeks, the company sold three previous cargoes of natural gasoline, one cargo of Loreto crude and one cargo of Mayna crude.

Bidders can submit offers until February 18 for this tender and prices must be indexed to naphtha from Northwest Europe or Japan. Natural gasoline prices from Mont Belvieu can be used as reference as well.

Partners from blocks 88 and 56 in Peru also include U.S. firm Hunt Oil, Korean SK Innovation, Argentina’s Tecpetrol, Spain’s Repsol and Algeria’s Sonatrach.
