CLASTIC RESERVOIRS
- Discipline: Reservoir Engineering
- Level: Intermediate
- Duration: 4 Days
The main objective of a development team is to identify the type and scale of heterogeneity that is most likely to affect the distribution of non-recovered mobile oil and gas in their subsurface reservoirs. The clastic depositional environment is particularly complex and many factors may cause a lower than expected recovery. Outcrops, cores, borehole images, logs, production test and reservoir level seismic can help provide detailed information about the architecture, fluid flow behavior and the heterogeneities in a reservoir.
This course aims at:
- Understanding the depositional parameters defining the reservoir architecture
- The use of tools to predict subsurface reservoir architecture and
- The impact of the heterogeneities on reservoir performance at different scales
- Framework for reservoir modelling
- Depositional processes and deposits.
- Geological features influencing hydrocarbon recovery.
- Clastic Reservoir Architecture, determination of architecture from seismic, logs, tests and core data
- Geologic controls on porosity and permeability.
- Trap type and compartmentalization of the reservoir
- Faults, fractures and fluid flow. Sealing capacity of faults; shale baffles.
- Core acquisition, analysis and interpretation.
- From geological data to engineering models.
- Principles of up scaling and application of Geostatistics.
- Capturing subsurface uncertainties in volume estimates.
Geophysicists, geologists, petrophysicists and reservoir engineers involved in exploration, appraisal and development of clastic oil and gas accumulations.
