CARBONATE RESERVOIRS

This rigorous workshop is a must for geoscientists dealing with exploration for and exploitation of carbonate reservoirs. The seminar emphasizes the complexity of carbonate porosity. Its modification and evolution will be discussed in a sea-level driven sequence stratigraphic framework. Case histories and exercises from around the world will be utilized throughout to illustrate important concepts. These exercises and case histories give the participant experience in developing viable exploration and exploitation strategies for carbonate terrains.

How to

  • Recognize basic characteristics of carbonates important to reservoirdevelopment
  • Understand how sequence stratigraphy can be applied to carbonatesand mixed carbonate-siliciclastic systems
  • Understand the complexities of carbonate pore systems
  • Recognize the nature of carbonate porosity modification duringdiagenesis and the role of sea-level and climate in porosity modificationand gross reservoir heterogeneity
  • Develop viable exploration and exploitation strategies in  carbonateterrains  by working with subsurface datasets
