Pressure prediction using basin modeling
approaches requires a good understanding of spacial and temporal behavior of
matrix and fault rock properties. Wrong rock properties utilized in the models
very often result in significant inconsistencies with well data. Understanding
of these inconsistencies, however, can be utilized as an additional tool for
predicting fault seal properties through geologic time.
This paper presents an integrated
approach based on basin modeling combined with diagenetic and mechanical
predictions of fault and matrix rock properties. Multiple iterations allow
elimination of unrealistic scenarios and focus on scenarios that should be
taken into consideration in pressure prediction, prospect appraisal, etc.
