As of 2 November 2018, Union Cuba-PetrÃ³leo (CUPET) announced it has been producing a medium grade crude (22Â° gravity) oil discovery located northeast of Havana on the northwestern coast of Cuba. The well was identified as the Bacuranao 300LÂ which was drilled to a depth below 2,400 m which is the depth at which the completion was made. No information was released on the specifics of the well other than to say the well has been producing for the last 10 months.  The well is in the North Cuban Province Basin which is where most of the production in Cuba is found however at a shallower depth of between 1,200 m - 1,800 m. Plays in the North Cuban province are characterized by fractured plays, with the Upper Jurassic to Cretaceous carbonates being the major reservoirs, and structural and porosity pinch-out being the dominant traps. Structural traps are generally faulted asymmetric anticlines in thrusts and thrust stacks. Six plays have been established by discoveries by February 2017, among which the Upper Jurassic-Neocomian Fractured Carbonate Stratigraphic-Structural and Middle-Upper Cretaceous Fractured Carbonate Stratigraphic-Structural plays are the most prolific plays containing more than 90% reserves in the basin. Fractured Serpentinite and Paleogene Clastics Stratigraphic-Structural plays are the minor plays in the basin.
Bacuranao 300L (CUPET 100%) in North Cuban Province, an oil find was made perhaps a year ago in NW Cuba, reportedly producing 22Â° API oil since Dec â17. No further info.
