Clastic Reservoir Characterization

Clastic hydrocarbon reservoirs hold more than 40% of world oil and 60% of world gas reserves. Sandstones provide the best known conventional reservoirs although more and more unconventional tight reservoirs including low porosity and permeability sandstones, siltstones and shales are being exploited for oil and gas production.

The objectives of this training course are to understand the deposition of clastic reservoir sequences and with the use of sequence stratigraphy and integrated stratigraphic analysis to further constrain geological models. Ultimately it can be used to predict and discover more hydrocarbon plays by understanding where to look for these systems tracts in a typical basin setting. These techniques will also be used to improve the estimation of play and prospect risk and to determine what lithology is going to be drilled ahead of the drill bit.

An overview of depositional environments and characteristics of unconventional reservoirs will also be discussed. This PetroKnowledge course will be presented as a 5-day interactive course dealing with the fundamentals of clastic reservoir characterization and the practical and predictive applications of sequence stratigraphy. It will include also exercises and some case histories for some interpretation and workshop discussion.

This training course will feature:

• Clastic reservoir characteristics and depositional environments an introduction.
• An overview of different types of sedimentary basins.
• Clastic reservoir systems tracts, lowstand delta, valley/canyon fill, basin floor fans, highstand and transgressive stands.
• An overview of clastic reservoir petrography, matrix and cements.
• Core and sidewall core analyses, sedimentary logs and integration of log data.
• An overview of petrophysical characteristics of sandstone reservoirs.
• The models and principles of seismic and sequence stratigraphy.
• Sequence definition from wells and seismic.
• Sequence stratigraphy in lacustrine environments.
• Unconventional clastic hydrocarbon reservoirs.
• Integration of other stratigraphic information, biostratigraphical, radiometric dating, chemostratigraphical.

This training course is suitable for exploration, development geologists, geophysicists and upstream subsurface professionals 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.
