CARBONATE RESERVOIR GEOLOGY 31 January – 4 February 2016 | Abu Dhabi , UAE

Overview This course is 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. The course demonstrates the value of the reservoir model in volumetric assessment and development of carbonate reservoirs. Extensive practical sessions can utilise your own data or Robertson CGG Company’s extensive non-exclusive data.

Key Objectives in Attending: Understand carbonate depositional systems and controls

Recognise and model controls on reservoir quality and pore systems, including diagenesis and fracturing

Understand and apply carbonate seismic stratigraphy and sequence stratigraphy.

Interpret log responses

Who should attend?

Petroleum geologists, explorationists, petrophysicists, geophysicists and engineers involved with exploration of

carbonate plays and development of carbonate reservoirs.

*Previous knowledge of carbonate sedimentology is not required.
