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:

1. Understanding the depositional parameters defining the reservoir architecture,

2. The use of tools to predict subsurface reservoir architecture and

3. The impact of the heterogeneities on reservoir performance at different scales

1.     Framework for reservoir modelling

2.     Depositional processes and deposits.

3.     Geological features influencing hydrocarbon recovery.

4.     Clastic Reservoir Architecture, determination of architecture from seismic, logs, tests and core data

5.     Geologic controls on porosity and permeability.

6.     Trap type and compartmentalization of the reservoir

7.     Faults, fractures and fluid flow. Sealing capacity of faults; shale baffles.

8.     Core acquisition, analysis and interpretation.

9.     From geological data to engineering models.

10.  Principles of up scaling and application of Geostatistics.

11.  Capturing subsurface uncertainties in volume estimates.

Geophysicists, geologists, petrophysicists and reservoir engineers involved in exploration, appraisal and development of clastic oil and gas accumulations.
