Abstract Since 1973 the Geological Survey of Canada has been making estimates of the petroleum resources for Canadian sedimentary basins. The purpose of this activity has been to provide a systematic approach to making an inventory of petroleum resources for departmental planning purposes. The resource evaluation was processed by the Hydrocarbon Assessment System Processor (HASP), devised by the Geological Survey of Canada. Since then, demands on the evaluation capability have increased and at the same time evaluation data have been increasingly applied to economic analyses. HASP can no longer be adapted to handle the new challenges. This study contains a probabilistic formulation for HASP and establishes a framework from which the following may be calculated: (1)distribution of number of pools; (2)expected rth largest pool size and its distribution; and (3)generation of reservoir parameters for a given pool size. Play 10 from the East Coast of Canada was used as an example to illustrate the applications of the analytical approach presented. This paper demonstrates that the analytical approach has more to offer than HASP.
