2008, Book chapter, Answering the challenges of production from deep-water reservoirs: Analogues and case histories to aid a new generatio
Stratigraphic models predict sedimentary architecture. Prediction requires understanding systems across a sufficient range of scales. To be predictive a model must address the interaction of multiple process-response relationships. For deep-water systems these processes include (1) subaqueous flow initiation and transformation, (2) linkages between channel, levee and lobe processes, and (3)...
