Fractured Carbonate Reservoirs

Audience

Petroleum geologists, explorationists, petrophysicists, geophysicists and engineers involved with exploration of carbonate plays and development of carbonate reservoirs.

Content

  • Carbonate Reservoirs. Basic principles, depositional concepts, grain types, textures and fabrics, environmental reconstruction
  • The reservoir model - depositional and diagenetic characteristics. Sabkha/tidal flat, lagoon, shelf, reef, barrier/shoal, slope and redeposited, aeolian and lacustrine, karst plays
  • Carbonate diagenesis. Primary and secondary porosity, compaction, pressure solution, cementation, dolomitization, porosity generation and destruction, fractures
  • Carbonate sequence stratigraphy. Log response in carbonate rocks
  • Fracture analysis. Fracture mechanics, data collection, analysis of fracture orientations, scaling relationships, fracture spacing, temporal relationships, controls on fracturing (including stratigraphy, faults and folds), complex fracture networks, brecciated carbonate rocks
  • Faults in carbonate rocks. Damage zones, styles of fault propagation, interaction and linkage in fault zones, fault reactivation, fault sealing and fluid flow
  • Stylolites in carbonate rocks. Mechanics of stylolites, controls on stylolites (lithological, tectonic, hydrocarbons), relationships between stylolites and fractures
  • Field analogues. Comparison between oil fields and exposed analogues
  • Reservoir assessment. Reservoir modeling, volumetric assessment in correlation and mapping, effects of capillary pressure, interface with engineering
