Clastic hydrocarbon reservoirs account for over 40% of global oil reserves and 60% of gas reserves. While sandstones are the most well-known conventional reservoirs, there is a growing trend in the exploitation of unconventional tight reservoirs such as low porosity and permeability sandstones, siltstones, and shales for oil and gas extraction.
This Energy training course aims to deepen understanding of the deposition of clastic reservoir sequences. It emphasizes the application of sequence stratigraphy and integrated stratigraphic analysis to refine geological models. This approach is crucial in predicting and discovering additional hydrocarbon plays by identifying ideal locations within a basin setting. Furthermore, these techniques assist in assessing play and prospect risks and help determine the lithology to target in drilling operations.
The training course also covers an overview of depositional environments and the characteristics of unconventional reservoirs. This five-day interactive training, which blends fundamental clastic reservoir characterization with the practical applications of sequence stratigraphy, will incorporate case studies and hands-on exercises for participants.
Key features of the Clastic Reservoir Characterization and Sequence Stratigraphy training course include:
- Introduction to clastic reservoir characteristics and depositional environments
- Overview of various sedimentary basins
- Exploration of clastic reservoir system tracts, including lowstand deltas, valley/canyon fills, basin floor fans, and highstand and transgressive stands
- An introduction to clastic reservoir petrography, matrix composition, and cementation
- Core and sidewall core analyses, sedimentary logs, and log data integration
- Understanding the petrophysical characteristics of sandstone reservoirs
- Seismic and sequence stratigraphy models and principles
- Sequence definition using well and seismic data
- Application of sequence stratigraphy in lacustrine environments
- Examination of unconventional clastic hydrocarbon reservoirs
- Integration of additional stratigraphic data, including biostratigraphy, radiometric dating, and chemostratigraphy
By the end of this Clastic Reservoir Characterization and Sequence Stratigraphy training course, participants will be able to:
- Identify various types of clastic hydrocarbon reservoirs and the palaeoenvironments where they are deposited
- Gain a comprehensive understanding of sedimentary basin types and their depositional patterns
- Effectively integrate sedimentary core, sidewall core, and log data
- Recognize and interpret the petrography of major clastic reservoir types
- Identify key sequences on seismic data
- Incorporate other geological data to recognize sequences and parasequences on well logs
- Use the terminology and definitions commonly employed in sequence and seismic stratigraphy
- Apply sequence and seismic stratigraphy in defining new plays and assisting with play and prospect risk assessments
- Understand different types of unconventional hydrocarbon reservoirs and the methods used to exploit them
The Energy 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 case studies to get participants actively involved in the interpretation and characterization of clastic reservoirs and to become aware of the predictive capabilities of applied sequence and seismic stratigraphy. Course participants are also encouraged to bring along sedimentary data, logs and seismic where appropriate from their own companies so that real working examples can be reviewed and interpreted.
The organization will have skilled personnel capable of analyzing reservoir rocks within the context of sequence stratigraphy, leading to a deeper understanding of reservoir constraints.
The application of global sequence stratigraphic techniques will help reduce risks associated with new exploration and development wells.
Participants in this Clastic Reservoir Characterization and Sequence Stratigraphy training course will gain the skills to perform sequence stratigraphic analysis on both clastic and carbonate rocks and understand how these rocks respond to field productivity.
Additionally, they will learn to apply advanced methods and techniques for sequence analysis, integrating all available data to develop the most accurate model for the area.
This Energy training course will be beneficial for those who are interested in understanding clastic reservoir depositional systems and how these can be interpreted in a sequence stratigraphical sense to identify predictive play trends. Its primary use will be for those involved in lead and prospect generation.
