Who Should Attend

E&P professionals involved in the prediction or delineation of clastic reservoirs. The course will be particularly useful for professionals early in their career and experienced professionals new to working with clastic reservoirs.

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 processes 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 that geometry.

The geometry of the depositional system is similar regardless of the depositional location or scale. As such, 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 was deposited on land or on a submarine fan, or whether it 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.

Modern and outcrop analogs will be used, along with subsurface examples to provide the interpreter with a sound understanding of the reservoir distribution and quality, both laterally and vertically of the clastic depositional systems most commonly encountered as oil and gas reservoirs. The course is exercise-oriented and taught in PowerPoint format. A course manual is provided. The exercises in this course are designed to give you a strong working knowledge of the many depositional settings you are likely to encounter in your career. They are aimed at helping you to learn how to recognize them from well logs, and how to map them. Days 4 & 5 will be a core workshop. Participants will describe cores from the depositional environments discussed in the previous 3 days

Learning Outcomes

  • Understand the basics of correlating well logs in clastic sequences utilizing shale and resistivity markers, interval thickness, sequence stacking patterns and cross-sections
  • Review the fundamental controls that influence clastic depositional systems
  • Understanding of the lateral and vertical reservoir distribution, reservoir characteristics and connectivity of braided, meandering, anastomosing, and entrenched river systems
  • Understanding of the lateral and vertical reservoir distribution, reservoir characteristics and connectivity of alluvial fans, deltas, and submarine fan systems
