    Day 1

    • Why carbonates are important to the oil industry
    • Why carbonates differ from siliciclastics
    • Basic controls on carbonate sedimentation and mixed clastic-carbonate systems
    • Carbonate systems and platform-types – basic facies patterns
    • Evolutionary controls on carbonate depositional systems through the Tertiary.
    • Introduction to sequence stratigraphy of carbonate systems
    • Case studies: examples of different types of carbonate reservoirs

    Day 2

    • Sequence stratigraphy vs lithostratigraphy
    • Carbonate response to relative sea-level change – RST, LST, TST, HST systems
    • Tectonic influences
    • Controls on relative sea-level change
    • Climatic influences - Icehouse/greenhouse climates
    • Principles of high-resolution sequence stratigraphy and cyclicity in carbonates, concepts of stacking patterns, Fischer plots
    • Seismic recognition of carbonate systems
    • Seismic sequence stratigraphy of carbonates
    • Seismic geometry and geomorphology of carbonate systems

    Day 3

    • Interpretation of carbonate sequences from wireline logs – including FMI logs
    • Diagenetic processes & models
    • Diagenetic techniques and applications of diagenetic studies in reservoir description.
    • Diagenesis exercise

    Day 4

    • Carbonate micropore systems
    • Carbonate matrix pore systems
    • Carbonate macropore systems - karst, brecciated and fracture systems.
    • Controls on the layering of pore systems in carbonates
    • Porosity-permeability exercise
    • Principles of geomodelling of carbonate reservoirs.
    • Objectives and work flows for describing carbonate reservoirs
    • Flow units in carbonate reservoirs

    Day 5

    • Conceptual geological models
    • Selection of appropriate analogue models for carbonate reservoirs - modern carbonate systems; dimensions of carbonate bodies
    • Heterogeneities of carbonate systems; scale and origin
    • Role of outcrop studies in reservoir geomodelling
