In the present time, many companies try to diversify risk of exploration projects all over the world. Therefore, big international oil and gas companies have to evaluate petroleum basins based on available data under limited time limits. During the ranking of oil and gas basins, petroleum companies face a lack of necessary geological and geophysical data and resources for estimation. This fact does not allow companies to conduct completed estimation of potential of basins. Based on these restrictions, authors proposed express method for ranking of oil and gas basins using available statistical data. Such method was tested in African continent. The proposed approach of express assessment includes the algorithms of estimation of potential hydrocarbon in place (YET), rise of volume of hydrocarbon over the decade, and relative volume of hydrocarbon in place. Based on proposed way to rank petroleum basins and further systematization of petroleum basins based on study level (greenfields, mature basins etc.) additional geographic clustering of oil and gas basins allows to conduct additional filter of basins and identify list of petroleum basins for further detailed elaboration.
Proposed method allows to estimate resources base of oil and gas basins is quite effective for identification new area of exploration with limited resources and geological and geophysical data. Advantages of such method are relative simplicity and small time spending. The main disadvantages of our approach are complexity and performance-enhancing gathering of statistics of petroleum basins.
