Who Should Attend
Course is geared to geologists needing a review and update as well as to petroleum reservoir engineers and geoscientists working on reservoir modeling and production in deltaic reservoirs.
Course provides a theoretical framework for understanding how deltas originate as well as be a practical guide for interpreting and mapping ancient delta systems in subsurface.
This 3-day short course will provide both a theoretical framework for understanding how deltas originate as well as be a practical guide for interpreting and mapping ancient delta systems in subsurface. The course will cover basic definitions, theory of delta forming process and the significance for recognizing these processes in ancient systems, a description of the essential facies components of a delta and the implications for subsurface facies architecture, and finally a survey of the different types of delta systems. Emphasis will be on recognizing river-, tide-, wave- and mixed-influence delta systems. Many of the examples are from the Cretaceous Western Interior Seaway, including the Dunvegan Formation and Milk River/Chungo in the Alberta basin.
Several case histories, emphasizing both exploration and production scale characteristics will be covered including; The Dunvegan Delta (Alberta) and Prudhoe Bay Field (Alaska). In addition, several outcrop examples will be discussed to give participants an idea of the lateral heterogeneity in delta systems and its effect on reservoir flow behaviour.
The course will include a series of powerpoint lectures, followed by several well-log correlation and core interpretation exercises. Core examples will be from the Dunvegan Formation in Alberta. The course is designed as an up-to-date review of the last 25 years of new ideas in deltaic sedimentology and will appeal to geologists needing a review and update as well as to reservoir engineers and geoscientists working on reservoir modeling and production in deltaic reservoirs.
