Presentation / Conference
Waltham, D. A., Rowley, P. J., Burgess, P. M., & MacLean, S. (2012, February). Conditional frequency mapping of move reservoir sedimentation models for improved play assessment. Paper presented at Petroleum Play Assessment

Stratigraphic forward models encode what we know about dynamic stratigraphy in the form of a numerical model that can make various types of predictions of stratal geometries and facies distributions. Unfortunately, limited knowledge of the physical l... Read More about Conditional frequency mapping of move reservoir sedimentation models for improved play assessment.
