Levitt-1 spudded on 4 July 2015. The shallow hole section has been drilled 73m, in a water depth of 1163m to the current depth of 1262 mRT and the conductor casing has been set. Preparations are underway to commence drilling in the 17-1/2in hole section last week.
The Ocean America semisubmersible drilling rig is being used to drill the well which is targeting a net unrisked prospective resource best estimate of 110 MMbbl. Total depth is expected to be reached during early August.
Levitt-1 is designed to test the presence of a working petroleum system generating from the Wigmore sub-basin. The sub-basin contains a significant thickness of Jurassic source rocks of the same age as those known to charge petroleum accumulations elsewhere in the basin. The well is located to evaluate the deeper North Rankin and the shallower Legendre formations, which are expected to receive hydrocarbons migrating from the oil mature source kitchen. A successful result would open up a new exploration play in the Carnarvon basin.
Quadrant Energy Australia is the operator of WA-482-P with 50% interest. Partner Karoon has a material 50% equity interest in WA-482-P and is carried for 90% of the cost of the well.
