Carnarvon: Roc South-1 added to 2019 drill programme

Published by

  • Roc South-1 well will be drilled immediately after Dorado-2 well in 2019.
  • Low risk target estimated to contain 74 million boe (Pmean, gross).
  • Tie back distance to the world class Dorado field.

Carnarvon Petroleum Limited (‘Carnarvon’) is pleased to announce that the Roc-South-1 exploration well is going to be drilled in 2019. The well will be drilled immediately after the nearby Dorado-2 appraisal well is completed and the Noble Tom Prosser rig will then finish its 2019 drilling campaign for the joint venture with the Dorado-3 appraisal well.

Roc South has a very similar geological trap structure to Dorado and like Dorado is situated up-dip of the Roc structure.

Given the very similar seismic characteristics between Dorado and Roc South, and what is anticipated to be an identical oil sourcing mechanism, the Roc South prospect has a relatively high chance of geological success of 63%.

With the crest of Roc South being around 13 km from the crest of the Dorado structure, drilling success at Roc South would likely result in this structure being developed with the Dorado field.

Roc South-1 is situated in the WA-437-P Permit. The joint venture partners are Carnarvon (20%) and Santos Limited (80%, operator).

Managing Director Adrian Cook said:

“The addition of the Roc South-1 well to the 2019 drilling campaign makes a great deal of sense given the large size of the prospect and the high chance of discovery by industry standards.”

“The joint venture has ambitions to make a Final Investment Decision to develop the Dorado field in 2020 and given the close proximity, Carnarvon anticipates that success at Roc South would mean it would likely form part of the world class Dorado project.”
