These permit applications are being actively progressed by Central in consultation with the NT DPIR and CLC. Central believes there is a reasonable expectation of the permit applications for 92, 129 and 160 to be granted in the near future.

Description and Geology

The Wiso Basin is a large sedimentary basin of 160,000km2, with the Lander Trough (30,000km2) at the southern margin dipping southwards, and terminating against the Arunta Block. Current gravity modelling indicates northwest to southeast trending depocentres in the Lander Trough to contain 4,500 to 5,000 metres of sediments. Potential source rocks of the Montejinni Limestone have been mapped in outcrop and shallow drill holes and are thought to be analogous to the Mid-Cambrian Thorntonia Limestone in the Southern Georgina Basin. Preliminary gravity modeling suggests structure characterized by a series of terraces that parallel the southern margin of the basin.  The basin is sparsely explored, with no modern seismic data and well penetrations are limited to a few stratigraphic wells up to 130 metres deep on the north-east margin. Oils shows were encountered in several of these wells.


Gravity and magnetics data acquired by NTGS and GA up to 2013 has been interpreted, providing estimates of sediment thickness, and identifying possible structures. The work program for these permits includes seismic acquisition which will be targeted at delineating structural trends such as those identified on potential field data.
