An object-based model for predicting the locations of undiscovered oil and gas resources,western Sverdrup Basin,Canada

摘要

A petroleum pool,that has a common petroleum/water contact and a distinctive pressure regime,is a fundamental unit of petroleum accumulation,and can be treated as a natural object.The prediction of the undiscovered petroleum pool locations can be performed employing a method similar to that used to predict sand channels in a clastic reservoir formation.This paper presents an example for the prediction of possible locations of undiscovered petroleum pools in the western Sverdrup Basin,Arctic Canada using an object-based model.This model simultaneously considers the information from the basic geological conditions for the formation of petroleum pools and the spatial correlation among the pools.The simulated results indicate that the object-based model improves predictions of petroleum occurrences by incorporating spatial correlation information into the model and by checking the consistency of the model with geological constraints.
