Finder adds new WA exploration permit

Finder Exploration has added a new exploration permit to the portfolio – AC/P 61. The permit, which Finder has 100% interest, is located in the Vulcan Sub-basin, western Bonaparte Basin in the Timor Sea, approximately 250km offshore and 650km from Darwin off the northwest coast of Western Australia. It covers an area of 335sq km, in water depths ranging from 125-340m.

AC/P 61 is surrounded by oil discoveries: the Tenacious oil field (yet to be developed) immediately to the west of the permit; the depleted Jabiru oil field immediately south of the permit (which produced 120 MMbbls of oil); the yet-to be-developed Audacious oil field immediately to the east of the permit; the Oliver gas/oil discovery is immediately to the north of the permit; the Cash/Maple gas field complex is about 30km to the west of the permit.

Four petroleum systems have currently been identified:

  • Tithonian fluvio-deltaic to basin floor fans sandstones of the Upper Vulcan Formation charged from Oxfordian to Kimmeridgian and Plover oil prone source rocks
  • Middle Jurassic fluvio-deltaic sandstones of the Plover Formation charged from Plover Formation source rocks
  • Lower Jurassic to uppermost Triassic fluvio-deltaic sandstones of the Nome Formation charged from Plover Formation source rocks
  • Upper Triassic deltaic sandstones of the Pollard Formation charged from Plover Formation source rocks

The permit contains the Gem Prospect, an intra-graben Jabiru/Challis look-a-like horst block. As currently mapped the Gem Prospect has a Jurassic Oxfordian depth closure of up to 7.9sq km with some 190m of vertical relief. Other leads are identified within the permit, such as the Douglas Updip Lead and a possible extension of the Tenacious oil field into the Permit.

The Onnia 3D seismic survey fully covers the permit, and a broadband pre-stack depth migration reprocessing effort will include the adjacent offset well ties from the Oliver, Tenacious, and Audacious oil and gas fields to deliver full permit coverage.
