The operator of the high-profile Buffalo-10 oil appraisal well offshore Timor-Leste has called a trading halt in its shares pending news on the well results.

Carnarvon Petroleum said Wednesday it requested an immediate trading halt, "pending the release of an announcement in relation to the Buffalo-10 well result".

The trading halt will end on the earlier of the start of normal trading on 21 January 2022 or when the well results announcement is released.

The Buffalo-10 well began drilling on 31 December 2021 using the jack-up Valaris 107.

Success could spur a redevelopment of the buffalo field which was shut in, some would argue prematurely, in 2004.

The field sits in Timor-Leste's exclusive waters, and is owned by Carnarvon and 50:50 partner Advance Energy.
