Kurdish Peshmerga forces say they have retaken oilfields near Mosul in north Iraq from Islamic State (IS) militants.
The attack on the three Ain Zalah installations began on Thursday morning, they said, but the militants blew them all up as they retreated.
The area is part of a large swathe of territory in northern Iraq overrun by Islamic State in recent weeks.
Iraqi and Kurdish forces backed by US air strikes have regained some ground, including the vital Mosul dam.
IS-led violence has driven an estimated 1.2 million Iraqis from their homes.
Whole communities of minority Yazidis and Christians have been forced to flee in the north, along with Shia Iraqis, whom IS do not regard as true Muslims.
