This Feature Class contains polygon features that summarise the exploration potential of the Eocene succession within sedimentary basins in the Northwest Province (Taranaki, Deepwater Taranaki, and Reinga-Northland basins). Areas where all of the requirements for oil or gas accumulation are present are indicated as having high exploration potential. Areas where all the requirements are not optimum, but may be present are indicated as areas of moderate exploration potential. Areas of low exploration potential indicates that on the basis of currently available open-file information there is a high risk for one or more of the petroleum systems elements not being able to effectively contribute to the petroleum system in that area. It is important to note that a rating of low exploration potential does not conclusively rule it out; rather, there is a high degree of uncertainty associated with presence of one or more of the petroleum system elements. For any given prospective area, more detailed work and data acquisition would be required. For more information about these data please refer to: Arnot, M.J. and Bland, K.J. et al. (Compilers), 2016.
