ASX Announcement

Earthquake in PNG

26 February 2018

Oil Search reports that at 03.44 (PNG local time) on 26 February 2018, a magnitude 7.5 earthquake struck in the PNG Highlands. There have also been a series of aftershocks.

Oil Search's primary concern is the safety of our employees and contractors. The Company is presently confirming that all personnel have been accounted for. No injuries have been reported so far.

As a precautionary measure and in order to assess any damage to facilities, Oil Search's production operations in the PNG Highlands are in the process of being shut-down. ExxonMobil PNG Ltd has confirmed that the PNG LNG facility at Hides has also been safely shut down.

We are also monitoring the impact on people in our local communities and will assist the relevant authorities, where possible.

We will keep the market advised of any material updates.
