At both the exploration and reservoir scales, sequence stratigraphy offers a potent tool for estimating the geographical and temporal distribution of reservoir, source, and seal rocks within a stratigraphic interval. This Carbonate and Siliciclastic Sequence Stratigraphic in Oil and Gas Exploration 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 the oil and gas industry.
The study of sequence stratigraphy’s concepts and practical applications, as well as a discussion of how this advances our knowledge of underground reservoirs, are covered. Additionally, the diagenesis of carbonate rocks is examined and, when applicable, placed within a sequence stratigraphic framework. Finally, integrating all subsurface data to de-risk hydrocarbon exploration and development from a sequence Stratigraphy point of view.
Upon the successful completion of the Carbonate and Siliciclastic Sequence Stratigraphic in Oil and Gas Exploration, participants will:
- Understand what are the different types of carbonate hydrocarbon reservoirs and the different palaeo-environments in which they are deposited
- Integrate sedimentary core, sidewall core, and log data for carbonate facies
- Be able to recognize and interpret the petrography of the main carbonate reservoir types
- Be able to identify the main sequences of seismic
- Be able to integrate other geological data and then identify sequences and parasequences on well logs
- Be conversant with the terms and definitions used in carbonate sequence and seismic stratigraphy
- Be able to use sequence and seismic stratigraphy towards new play definition and as an aid in play and prospect risking
- Understand the processes that control carbonate deposition
- Understand what controls porosity and therefore reservoir development in carbonate rocks
- Be able to understand the complex controls on the deposition of carbonate rocks and both primary and secondary depositional environments
This training course is suitable for a wide range of professionals but will greatly benefit:
- Geologists (Exploration and Development)
- Seismic Interpreters
- Drilling Engineers
- Reservoir Engineers
- Technical Support Personnel
- Team Leaders
This training seminar will utilize a variety of proven adult learning techniques to ensure maximum understanding, comprehension, and retention of the information presented. The participants will work together using real data to apply all the workflow and project their prior knowledge and experience onto the course. They are also encouraged to bring their own data so that real working examples can be reviewed and interpreted.
Pre & Post course assessments will be used to measure the effectiveness of this training.
