Carnarvon Petroleum Limited (Carnarvon) has announced that the Noble Tom Prosser jackup drilling rig has been contracted to drill the Pavo-1 and Apus-1 exploration wells in the Dorado Field in the Bedout basin offshore western Australia.

The drilling programme is expected to commence in late 2021 with the Pavo-1 well and will be immediately followed by Apus-1. Both prospects hold the potential to materially increase the aggregate development resource for the Dorado field if successful with the Pavo-1 well targeting 101mnboe and Apus-1 targeting 306mnboe.

Both of the exploration targets also have the potential to be tied back to existing infrastructure on the Dorado field which could provide significantly enhance economic outcomes, minimise additional capital investment requirements and shorten time periods to first production from the tie back fields.

With the drilling rig contracted, the operator will now proceed to secure the remaining equipment, services and approvals required to commence drilling operations

Managing Director and CEO of Carnarvon, Adrian Cook, said, “Given the potential resource size and development aggregation benefits, these two drilling targets provide very attractive and meaningful opportunities for Carnarvon. This news in locking in this rig is another clear point of progression in the advancement of the world class Bedout Basin. We are looking forward to an exciting year ahead with multiple drilling operations progressing to plan as well as the advancement of our Dorado development pre-FEED and FEED activities.”

Repeating history?

The Noble Tom Prosser jack-up drilling rig was previously used by Carnarvon and its operating partner in 2019 on the Dorado-2 and Dorado-3 appraisal wells and the operators will no doubt be hoping for a repeat of fortunes; Dorado-2 operations encountered 85m of net reservoir, a discovery far more significant than original estimations, while Dorado-3 initially discovered confirmed hydrocarbons in three reservoirs and returned strong results in the subsequent flow tests with the Caley reservoir achieving a maximum measured rate of approximately 11,100bbl per day and 21mn cu ft of associated gas per day.
