Mapping and Interpreting Deep Water Clastic Reservoirs (1 day course)

Date: February 21, 2017.

Venue: Shangrila- Sule, Yangon, Myanmar.

Course Description:

Our ability to predict reservoir presence or map net reservoir in clastic depositional systems is dependent on our understanding of the depositional geometries of the various depositional systems and the variation of patterns within those systems. The process associated with sediment delivery and sediment dispersal is the fundamental control on the architectural geometry of a depositional system. The processes associated with the interplay between sediment input and accommodation space are the fundamental controls on the lateral and vertical stacking patterns within a depositional setting.


The depositional geometries and the patterns within those geometries are similar for each depositional system regardless of whether their depositional setting is sub-aerial or sub-aqueous. For example, dispersal systems are all lobate in geometry whether they are deposited at the base of a mountain or at the base of slope in 400 meters of water. Likewise, the four basic patterns seen in delivery systems are the same whether they are deposited in a subaerial environment or a subaqueous environment.


For each depositional system, the geometries and the patterns within those geometries are also fractal. That is the pattern is the same at all scales from several centimeters to hundreds of kilometers. In that the geometry of the depositional systems are similar regardless of depositional setting or scale, the patterns within the geometries are also similar, and, therefore, predictable. This is a powerful concept that the interpreter can use in predicting depositional geometries and patterns. Whether the reservoir being studied is 100’s of kilometers in scale or a kilometer, the geometry of the deposit is similar. Therefore, interpreters need only become familiar with the basic geometries of clastic depositional systems and the patterns that occur within those geometries.


For deepwater deposits, there are considerable differences in the distribution of reservoir facies and the lateral connectivity between slope and toe of slope deposits. Slope deposits exhibit the linear characteristics of delivery systems whereas turbidites deposited at the toe of slope or in ponded basins exhibit the lobate characteristics of dispersal systems.The class will illustrate through lecture and exercises the depositional geometries of both delivery and dispersal systems in general, then focus on deepwater depositional systems. We will examine the facies distribution in slope bypass turbidites and in constrained or toe of slope deposits.
