Karoon Energy Ltd., Melbourne, has spudded its Marina-1 wildcat in Block Z-38 in the Tumbes sub-basin offshore Peru.
The Stena Forth drillship is estimated to take about a month for the program, drilling to a total depth of 3000 m subsea.
Karoon said the Marina prospect has a gross prospective resource estimate of 256 MMbbl of oil. The prospect is a large fault-bounded structure with multiple targets likely in the Tertiary-age La Cruz to Cardalitos formations 900-3,000 m subsea.
Karoon defined the structures with 3D data. Nearby hydrocarbon seeps indicate that migration of hydrocarbons has occurred.
Karoon is operator with 40% interest. Partners are Tullow Oil Ltd. 35% and Pitkin Petroleum 25%.
