Summary

An understanding and application of the principles of sequence stratigraphy is essential for the successful prediction and analysis of seismic and well log facies in the subsurface. This seismic and well facies mapping course includes multiple class exercises and case history examples, integrated with lectures on sequence stratigraphic concepts, providing the relevant knowledge and skills for participants to successfully use sequence stratigraphy in exploration and prospect identification. 

Duration and Training Method

A five-day classroom course comprising of classroom-based lectures supported by exercises.

Participants will learn to:

  1. Formulate the observational techniques used to interpret both well and seismic facies (clastic and carbonate) within a simple stratigraphic framework.
  2. Evaluate the use and integration of the Exxon model, system tracts, chronostratigraphy and seismic stratigraphy.
  3. Assess the principles of facies mapping methods to sequence stratigraphy and describe the possible pitfalls in interpretation; mispicking, scale, depositional environment, mounds and (HRDZ's) Hydrocarbon Related Diagenetic Zones.
  4. Appraise and locate Lowstand facies; slope fans, prograding complexes, incise valleys, sediment waves and contourites, basin floor fans and debrites.
  5. Appraise and recognise Transgressive facies; basal transgressive sands and source rocks.
  6. Appraise and pin point Highstand facies; prograding slope and shelves, fluvial and alluvial sediments.

The course examines well and seismic facies, both clastics and carbonates, within a simple sequence stratigraphic framework.The class will operate more as a workshop format as there are multiple operational exercises which have lectures interspersed between them to emphasise key concepts.The aim is to supply participants with an international spread of real-world examples which can serve as an analogue database for future work. The lectures will show pitfalls and things that went wrong as well as where seismic facies mapping worked. Participants will have the opportunity to practice construction of seismic facies maps during the course.

Who should attend

This workshop is hands-on and is suitable for both geologists and geophysicists-anyone interested in deducing geology from seismic and well data. 

Prerequisites and linking courses

Previous seismic experience is useful but not mandatory. Attendance on course N007 (Seismic and Sequence Stratigraphy for Play Prediction and Basin Analysis) would also be beneficial but is not a formal prerequisite. Other courses which link well include N251 (Well Log Sequence Stratigraphy: Applications to Exploration and Production), N011 (High Resolution Sequence Stratigraphy: Reservoir Applications (Utah, USA)) and N091 (Carbonate Reservoir Architecture and Applied Carbonate Sequence Stratigraphy (West Texas and SE New Mexico, USA)).

It's really great. One of the best courses I've ever attended.
