PESA SA/NT October Technical Luncheon

Science Tested by the Drill Bit: Roebuck Basin

When: Wednesday 31st October, 12pm for 12:30

Where: Club Braggs at The Public Schools Club, 207 East Terrace, Adelaide SA 5000

Speaker: Claudia Valenti & Jeff Goodall, Carnarvon Petroleum

Regional work, initiated five years ago, by Carnarvon Petroleum, on the Triassic of the inboard NW Shelf, has crystallised thoughts and ideas on the oil potential of this stratigraphic interval. Detailed geological work has, and is, run in parallel on both the inboard Carnarvon and the Roebuck Basins. The philosophy was to start again with the geological thinking, developing revised geological concepts. This conceptual work on the early and middle Triassic has now delivered, with the discoveries at Phoenix South, Roc and Dorado, with a refined understanding of early and middle Triassic hydrocarbon petroleum system within the basins achieved and demonstrated.

A Late Triassic petroleum system, predominantly carbonate, has been noted by Carnarvon geoscientists as working in the areas between Timor Island and Buru/Seram. This initiated the question; does this also exist on the NW Shelf?

The drilling of the Anhalt-1 and Hannover South-1 wells in the Rowley Sub-basin Carnarvon identified fair to good source rock potential, with new analysis, within the interpreted, late Triassic, carbonate platform deposits. It is proposed that these Late Triassic platform to marginal marine, clastic/carbonate source rocks are better developed in mapped, mini-basins, to the south of these wells, directly analogous to the marine sequences of Sulawesi, the Birds Head area of Indonesia/West Papua and onshore Timor.

Basin scale mapping with burial history modelling match the existing well results and have identified areas where these Late Triassic, carbonate source rocks have generated hydrocarbons and adding a new, late Triassic petroleum system within the Roebuck Basin.

Following graduation from University College London, Jeff Goodall spent a period of ten years working on North Sea and West African projects which was followed by a decision to migrate to Australia to work for Santos, Adelaide. Roles in Santos included working in the stratigraphy group and later as an exploration geologist, working primarily on the NW Shelf and Indonesian assets.

After fourteen years in Santos, a change to a stratigraphic and geological consultancy role with the establishment of the Morgan Goodall Palaeo (MGP) laboratory and geoscience consulting business in Perth, with a diverse range of regional stratigraphical projects and drilling campaigns on the NW Shelf, PNG. A role as chief geologist in Indonesia with Husky and CNNOC was also accepted at the same time, with the drilling of six commercial discoveries in the Madura Straits.

In 2013 a move back to Perth, after two years in Indonesia, was quickly followed by consulting work for Carnarvon Petroleum, leading to a full-time role as their chief geologist in 2014, working on a variety of NW Shelf projects and helping develop ideas on the inboard Triassic exploration.

Jeff still holds a directorship at MGP.
