About this Training Course

This 5 full-day course has been designed to develop skills in understanding the geometry and petrophysical characteristics of carbonate reservoirs.

Depositional fabric, grain type and size and subsequent diagenetic modifications are the major controls on carbonate reservoir behaviour.

The complex inter-relationship of the depositional and burial history can be unravelled to allow prediction of reservoir facies and reconstruction of three-dimensional reservoir models.

This course will demonstrate the value of the reservoir model in volumetric assessment and development of carbonate reservoirs.

*Previous knowledge of carbonate sedimentology is not required.

Course Content in Summary:

1. Carbonate reservoirs: Basic principles; depositional concepts; grain types; textures and fabrics; environmental reconstruction.
2. The reservoir model – depositional and diagenetic characteristics: Sabkha/tidal flat; lagoon; shelf; reef (rudist and coral/algal); barrier/shoal; slope and redeposited; aeolian and lacustrine; karst plays.
3. Carbonate diagenesis: Primary and secondary porosity; compaction; pressure solution; cementation; dolomitisation; porosity generation and destruction; fractures.
4. Carbonate sequence stratigraphy
5. Log response in carbonate rocks: Gamma; sonic; neutron; density; FMS.
6. Reservoir assessment: Fracture reservoirs; reservoir modelling; volumetric assessment in correlation and mapping; effects of capillary pressure; interface with engineering.
