Why Choose this Training Course?
Biostratigraphy is often run as a service in oil exploration & development for age and palaeoenvironmental interpretation. But the power that can be provided by critical insight of the data generated for detailed sequence analysis including unconformities and sequence breaks plus the identification of flooding and condensed surfaces and its use for facies identification (reservoir to non- reservoir) are often not optimally achieved. Subsequently neither are the desired high resolution stratigraphical correlations.
The integration of biostratigraphical data with seismic interpretations and sedimentological and petrographical data utilizes its power most efficiently. This training course sets out to illustrate this best use. The pitfalls with the use of biostratigraphical data will be discussed, which often relates to the geological context in which formations were deposited. By identifying them and often then utilizing them with regards to understanding the geology, this helps to unlock the tool and with it a realization of the possibilities that optimum use of this technique can bring.
This PetroKnowledge training course will introduce the applied use of biostratigraphy and sequence stratigraphy in both an exploration and development context with working examples from Africa, the Middle East, Southeast Asia and Europe, and will also cover both marine and non-marine sediments.
This training course will include:
- An introduction to the different microfossil groups
- A discussion on the laws of stratigraphy and how biostratigraphy can be used to determine a chronostratigraphy
- Which microfossil groups to use for which age of sediments and how they are used as palaeoenvironmental indicators
- What pitfalls to look for and how these can lead to a better geological understanding
- How to use biostratigraphy and bio facies to identify key seismic markers
- How to integrate biostratigraphical data with other geological data (sedimentological, petrographical, geochemical) to maximize its use
- How to use integrated biostratigraphical data to build a high-resolution sequence stratigraphy
- How biostratigraphy can be used in play definition and for play based exploration
- Working examples of applied stratigraphy for exploration and development from Africa, Asia and Europe
What are the Goals?
By the end of this training course, participants will be able to:
- Have knowledge of the different microfossil groups and in which ages of sediment and palaeoenvironment of deposition they can be utilized.
- Develop an understanding of how biostratigraphical data can be integrated with other geological data to optimize its use as an interpretative tool
- Develop an enhanced interpretation skill to recognize key seismic markers and how to interpret these as a geological sequence by integrating biostratigraphical data
- Interpret palaeoenvironment of deposition by using biostratigraphical assemblages
- Use biostratigraphy as a predictive tool in exploration and development
Who is this Training Course for?
This training course is suitable to a wide range of professionals but will greatly benefit:
- Exploration Geologists
- Development Geologists
- Seismic Interpreters
- Upstream subsurface professionals who are interested in optimally utilizing geological data as a predictive tool in sedimentary basins and for identifying hydrocarbon plays in active petroleum systems.
How will this Training Course be Presented?
The training course will be based around PowerPoint presentations for each module followed by interactive and participative individual and team exercises. There will also be workshop sessions based around real exploration and development examples to get participants to actively become aware of the predictive capabilities of applied biostratigraphy and sequence stratigraphy. Course participants are also encouraged to bring along biostratigraphic data, logs and seismic where appropriate from their own companies so that real working examples can be interpreted.
