"Chevron Mediterranean Limited (CML) can confirm that on November 14, 2023, the natural gas flow through the EMG pipeline resumed," it said in a statement.
Exports via EMG were halted on Oct. 10, three days after the conflict began.
The EMG pipeline runs from the southern Israeli town of Ashkelon, located some 10 km (6 miles) north of Gaza, to El-Arish in Egypt, where it connects to an onshore pipeline.
The 90-km pipeline is the main link between the Chevron-operated Leviathan offshore gas field and Egypt. The Leviathan consortium includes operator Chevron, Israel's NewMed Energy (NWMDp.TA) and Ratio Energies (RATIp.TA).
Chevron said on Monday it had resumed the supply of natural gas from the offshore Tamar field, a month after it was told by Israel to halt operations due to violence in the region.
