This course examines the processes leading to the formation and accumulation of carbonate & Siliciclastic rocks and how sequence stratigraphy provides a predictive method to understand the formation of these reservoirs and application in oil and gas industry.

The principles and the practical application of sequence stratigraphy are studied, together with discussion on how this improves our understanding of subsurface reservoirs. Diagenetic changes that carbonate rocks undergo are also analyzed, and, where possible, set within a sequence stratigraphic framework.

Finally, integrating all subsurface data to de-risk hydrocarbon exploration and development from sequence Stratigraphy point of view.


Learning Objectives

Upon the successful completion of the course, participants will:


ü  Understand what are the different types of carbonate hydrocarbon reservoir and the different palaeo-environments in which they are deposited

ü  Integrate sedimentary core, sidewall core and log data for carbonate facies

ü  Be able to recognize and interpret the petrography of the main carbonate reservoir types

ü  Be able to identify the main sequences on seismic

ü  Be able to integrate other geological data and then identify sequences and parasequences on well logs

ü  Be conversant with the terms and definitions used in carbonate sequence and seismic stratigraphy

ü  Be able to use sequence and seismic stratigraphy towards new play definition and as an aid in play and prospect risking

ü  Understand the processes that control carbonate deposition

ü  Understand what controls porosity and therefore reservoir development in carbonate rocks

ü  Be able to understand the complex controls on the deposition of carbonate rocks and both primary and secondary depositional environments

Training Methodology

The course will not only presented by showing and interpreting the material in detail, but also the participants will work together using a real data to apply all the workflow and to project their previous knowledge and experience onto the course, they also encouraged to bring their own data so that real working examples can be reviewed and interpreted.

  • Petrophysicists
  • Geo-Modelers
  • Geologists (Exploration and Development)
  • Sedimentologists
  • Seismic Interpreters
  • Drilling Engineers
  • Reservoir Engineers
  • Technical Support Personnel
