f Probabilistic Petroleum and Natural Gas Reserve Calculations by Volumetric Methods and Probabilistic Aggregation of Field Resource

od. It is proved that AUP method can be used in volumetric reserve estimations. To determine the total potential of more than one field or reservoir, two different methods are examined and “Sorting Diagrams Method” is developed to determine correlation coefficients between two fields which is indispensable component of realistic estimations. Also, applicability of AUP method to simulation applications is investigated and for this purpose two different methods are developed. The usability of these methods is discussed.
