Levitt-1, located in WA-482-P in the Carnarvon basin, was drilled to a total depth of 4929m where no hydrocarbon shows were noted. Petrophysical analysis of logging while drilling data indicated that the good quality reservoir of the Legendre and North Rankin formations to be water bearing, according to partner Karoon Gas Australia.
The JV is currently conducting a wireline logging program. Once complete, the well will be plugged and abandoned, and the current drilling program in WA-482-P will be complete. However, there is still hope for WA-482-P.
“Whilst a dry hole at Levitt-1 is disappointing, there remains enormous potential in the remainder of this large 13,539sq km permit,” Robert Hosking Karoon managing director said. “To the north and east in the Wigmore sub-basin, new 3D seismic shows the presence of many structures and a thicker Jurassic source interval than seen in offset wells. I remain very enthusiastic about the exploration potential in this permit.”
Over the next 12 months, geological and geophysical studies will delineate and rank the remaining prospects to find the most prospective locations to carry on with additional drilling programs.
The WA-482-P permit consists of multiple geological play types in varying locations and depths. Together, Levitt-1 and acquired Chrysalids and Capreolus 3D seismic surveys, will provide important information about the petroleum systems in the area. The JV will use the new well and 3D seismic data to progress the evaluation of areas.
Levitt-1 was spudded in early July using Diamond Offshore’s Ocean America semisubmersible drilling rig.
Quadrant 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.
