Roc, which has a 37.5% interest in Cliff Head, said production recommenced on Saturday after the company identified and fixed the unspecified electrical fault.
Current production from the field is 9000-10,000 barrels of oil per day from three of the six production wells.
Trucking of oil to the BP Refinery at Kwinana recommenced today and remaining production wells will be brought on stream in due course, the company said.
Roc recently said gross oil production at Cliff Head has generally ranged between 11,000 barrels of oil per day (bopd) and 12,500bopd, with a high of 15,800bopd.
The range is a result of intermittent downstream constraints, most recently relating to trucking capacity, which are currently being addressed, it said.
Cliff Head partners and their associated equities are Roc, AWE Oil (27.5%), Wandoo Petroleum, a Mitsui subsidiary (24%), Arc Energy (6%) and CIECO Exploration and Production (5%).
