Australia North Carnarvon exploration basin

Report summary
The vast majority of exploration drilling in the North Carnarvon basin has been in the Mesozoic Northwest Shelf play. However, over the last 10 years explorers have moved into the deepwater sector of the basin, resulting in large gas/condensate discoveries. Shelf exploration has also proven to be prolific and, in addition to the large gas volumes discovered, small, cheap oil developments have been quickly tied back to existing infrastructure. The basin currently supplies four LNG facilities, with Gorgon LNG and Wheatstone LNG delivering first cargoes in 2016 and 2017 respectively.The outlook for the basin is for a similar scale of exploration success, but with marginal economics due to the relatively high cost of exploration and development, particularly in the deepwater play where the largest discoveries are expected to be made. Shelf exploration remains relatively inexpensive, but pool sizes are expected to be small.
