CARNARVON Petroleum Limited reports that the Noble Tom Prosser jack-up drilling rig has been secured to drill an appraisal programme on the exciting Dorado oil discovery off the Western Australian coast.

The company said the shallow water depths mean that the Dorado Joint Venture is able to utilise a cost-effective jack-up drilling rig for its Dorado appraisal wells.

The JV is well versed in the capabilities of the Noble Tom Prosser which was also used to drill the Roc-1 discovery in this area in 2016.

The 2019 drilling programme is expected to include two Dorado appraisal wells that will focus on:

  • gaining further information on the volume of oil, gas and condensate discovered in the Dorado-1 well to build proved reserves which will underpin the Dorado development;
  • determining the flow properties of those hydrocarbons from the reservoirs intersected in order to optimise the Dorado development; and
  • obtaining additional data at different locations within the Dorado field.

“The incredible Dorado discovery earlier this year means we are highly motivated to appraise the oil, gas and condensate within the structure,” Carnarvon managing director Adrian Cook said.

“The objective in 2019 is to enhance our understanding of the volume of the resources recoverable and move to making a Final Investment Decision for development ideally in 2020.”

The Joint venture partners in exploration permit WA-437-P are Carnarvon (20%) and Santos Limited (80%, operator).
