National Iranian Oil Company (NIOC) and PGNIG, a leading Polish firm in the energy sector, have signed a partnership aimed at conducting evaluation studies on an Iranian oilfield, a report said.

Sumar oilfield, in the western province of Kermanshah, is estimated to hold 475 million barrels of in-situ crude oil, of which 70 million barrels would be recoverable, reported Iran Daily.

NIOC's deputy for Development and Engineering Department Gholamreza Manouchehri said that PGNIG has been given six months to conduct studies on the oilfield and present a report to NIOC.

NIOC's major strategy is to put the oilfield on tender, he added, highlighting that the final decision on developing the oilfield will be taken once a report is provided by the Polish company.
