WEST PERTH and ADELAIDE, Australia – Santos is preparing to re-start drilling operations on its Pavo-1 well, located offshore Western Australia, following a recent precautionary pause due to potential cyclone activity.

The Pavo-1 well, which is located in the WA-438-P exploration permit, was spud in February 2022, using the Noble Tom Prosser jack-up rig.

However, Santos was in late February forced to secure the well and prepare the rig for down-manning due to potential cyclone activity.

Santos is the operator of the WA-438-P permit with 70% interest and its partner is Carnarvon Energy with the remaining 30% interest.

According to Carnarvon’s update of March 11, the Pavo-1 well had drilled to around 3,282 meters Measured Depth (MD) in the 8 ½-in. hole before operations were suspended while the drilling rig was down-manned and the well made safe due to cyclone activity in the area.

The well intersected multiple sands within the Caley to Crespin reservoirs, with logging while drilling tools indicating porous and permeable reservoir intervals with similarity to the Dorado reservoir. Elevated gas readings and increased resistivity were observed between 2,944 meters MD and 3,001 meters MD indicating the presence of hydrocarbons.

The drilling rig has now returned to full manning levels and is preparing to re-start drilling and logging operations.

Upon re-start of operations, the well will be conditioned to run wireline operations while being deepened to approximately 3,600 meters MD to investigate the Milne and Dumont members.

An extensive wireline program will then be run over the Caley and Crespin reservoirs, where logging while drilling and surface gas readings indicated the presence of hydrocarbons in reservoir intervals.

Once the Pavo-1 well has been completed, the two partners plan to drill the second well in their campaign, the Apus-1 well, which is located around 20 km southwest of the Pavo-1 well location.
