Amadeus Basin


Centralian Superbasin: Officer Basin


Officer Basin

• Work recently commenced

• Analysis of new mineral cores

in WA and petroleum wells in

South Australia – potential for

cross-border collaboration

• New Field Work

• EIS Future Projects could

include seismic acquisition,

gravity acquisition, seismic

reprocessing

Canning Basin



Canning Basin Collaborative Core Analysis Project

• Collaborative research: Petroleum systems and CO2

geosequestration potential with GA and industry. Several

publications released already and more to come

Current participation:

Olympic 1 and Senagi 1 (Buru Energy)

Theia 1 (Finder Exploration)

• Digital Core Atlases:

Olympic 1 and Theia 1

released

Senagi 1 near complete

to be published 2018/2019


Canning Basin Field Work and Drone Technology

• Field Work: Prices Creek Group to correlate with

the subsurface Nambeet and Willara Formations;

and mapping the Lucas Outlier

• Bringing the outcrop to the office: creating

outcrop photogrammetry, amalgamating with

multiple analysis taken directly from field samples

stratigraphy and correlation of

Mid-Carboniferous – Lower

Permian palynology and

stratigraphy
