Summary

Business Impact: Attendance on this course will primarily aid in exploration but will also add value during appraisal, development and production of reservoirs and oil fields in extensional settings.

The course describes the sedimentology and stratigraphic evolution of rift-fill and post-rift successions in non-marine and marine settings, as a product of structural evolution, climate variation, and sea level change. These principles are applied to the acquisition and evaluation of exploration acreage and illustrated by worldwide case studies.

Duration and Training Method

This is a 5-day classroom course, with a combination of lectures and exercises. Lectures are informal to encourage discussion. There are both individual and team exercises that are drawn from rift basin data sets worldwide.

Participants will learn how to:

  1. Characterise rift basin types and tectonic regimes under which rift basins form and assess their probable structural evolution through pre-, syn- and post-rift stages of development.
  2. Compare models of rift basin evolution and contrast these with a range of real rifts.
  3. Assess sedimentary and stratigraphic features of rift basin fill.
  4. Assess the role of both climatic and tectonic controls in determining rift basin fill, especially as it relates to the deposition of likely source, reservoir and seal formations.
  5. Reconstruct likely sediment fairways based on the structural architecture of a given rift system and predict possible locations for source and reservoir facies.
  6. Apply sequence stratigraphic principles and models to both marine and non-marine rift basins.
  7. Appraise the petroleum systems in rifts and characterise both common and under-explored play concepts.

The focus of the course will be sedimentation and stratigraphic development in rift basins as a response to structural evolution. Sedimentary processes and products are discussed in detail as is their role in the generation and storage of hydrocarbons. A key component is a discussion of rift basin exploration plays and strategies for efficient acreage evaluation.

Who should attend

Geologists, sedimentologists, geophysicists, petrophysicists, petroleum engineers involved with exploration in rift basins or looking to broaden and deepen their knowledge of rift systems.

Prerequisites and linking courses

There are no prerequisites but participants are assumed to have a basic knowledge of structural geology and sedimentology.

This course is complementary to other courses focusing on extensional tectonics and fault systems, such as N041 (Extensional Tectonics and Normal Fault Patterns, Utah), N144 (Rift Systems, Faulting and Fault-Controlled Sedimentary Architecture: Gulf of Corinth (Greece)), and N407 (Predicting Reservoir and Petroleum Systems in Rifts and Extensional Basins (New Mexico & Colorado, USA)).
