Course Outline
Day 1

Introduction to Siliciclastic Reservoirs

  • Siliciclastic rocks: understanding sediment texture, detrital components, and depositional environments.
  • Sandstone characteristics: classification, minerals, source areas, and depositional markers.
  • Provenance and tectonic settings: exploring sandstone composition and its geological context.
  • Reservoir quality: examining the relationship between depositional environments, provenance, and grain size analysis.
  • Diagenesis: considering compaction, authigenic components, diagenetic environments, and sequences.
  • Analytical techniques: discussing SEM, XRD analyses, CL analysis for cement distribution, and the chronology of diagenesis.
Day 2

Sandstone Reservoir Quality Analysis

  • Reservoir quality: understanding its definition and methodologies, including the influence of cementation.
  • Porosity in sandstones: exploring different types and their significance.
  • Porosity-permeability analysis: methods for interpretation, including correlation with petrophysics from cuttings descriptions.
  • Utilizing outcrop analogues: estimating subsurface reservoir quality through geological comparisons.
  • Rock Typing: assessing petrophysical properties of cuttings, including analysis of rock types and classification schemes from oil industry methodologies.
  • Diagenetic controls: examining how diagenesis influences reservoir quality and porosity variations with depth and stratigraphy.
Day 3

Introduction to Carbonate Reservoirs 

  • Introduction to carbonate reservoirs: an overview of their characteristics and significance.
  • Limestone components: understanding carbonate depositional environments, facies, and variations in the geological record.
  • Matrix and authigenic components: exploring the relationship between taxa and mineralogy, alongside limestone classification.
  • Carbonate production rates: examining microfossils, paleoenvironmental markers, platform facies, and their response to sea level changes.
  • Carbonate diagenesis: considering processes such as neomorphism, compaction, marine, meteoric, and burial diagenesis.
  • Diagenetic markers: identifying stages of carbonate diagenesis and their implications.
  • Dolomite characteristics: studying textures, stable isotope signatures, and their significance in carbonate reservoirs.
Day 4

Carbonate Reservoir Quality Analysis

  • Carbonate diagenesis and reservoir quality: understanding dolomite texture, petrophysical implications, dolomitization models, and comparing limestone versus dolostone reservoir quality.
  • Porosity in carbonate rocks: exploring classification schemes, petrophysics based on carbonate rock types, factors influencing porosity preservation, and methods for estimating porosity.
  • Controls on reservoir quality: considering the influence of rock fabric, wireline logs, and porosity evolution over geological time.
  • Carbonate reservoir models: assessing reservoir quality in relation to porosity and petro-facies.
  • Rock typing: discussing concepts, petrophysical assessment methods, classification schemes, data sheets, and their relevance to reservoir quality.
  • Single well versus multi-well studies: highlighting the importance of regional correlations for understanding reservoir quality variations.
Day 5

Examples of Siliciclastic and Carbonate Reservoirs

  • Reservoir facies in a carbonate shelf, slope and basinal setting: Jurassic, Western Portugal.
  • Siliciclastic reservoirs of Oman: Aeolian, deltaic and marine sandstones and other reservoirs.
  • Visual estimation of porosity in sandstone and carbonate reservoirs.
  • Differences in the controls on reservoir quality between sandstones and carbonates
