Course Summary

This GLOMACS Reservoir Quality Analysis  of Sandstone & Carbonate Rock Types training program is designed to provide comprehensive guidance to geologists working in the oil industry on understanding the characteristics of sandstone and carbonate rocks relevant to reservoir quality. Through reservoir quality analysis, participants will learn to discern the primary factors influencing porosity and permeability evolution in sandstone and carbonate reservoirs, including depositional processes, provenance, and diagenetic changes (such as porosity evolution with burial depth, mineral composition, and diagenetic settings). Case studies from both sandstone and carbonate hydrocarbon reservoirs will be explored to enhance understanding.

This Reservoir Quality Analysis  of Sandstone & Carbonate Rock Types training course will highlight:

  • Introduction to siliciclastic and carbonate reservoirs, focusing on factors influencing reservoir quality.
  • Understand sandstone characteristics including composition, origin, diagenesis, and geological settings.
  • Understand carbonate features such as constituent types, classification, and diagenetic processes.
  • Conduct petrographic analyses (thin sections, scanning electron microscopy, cathodoluminescence), X-ray diffraction, QEMSCAN, and integrating results to assess reservoir quality.
  • Classify porosity, examining its evolution relative to burial depth, stratigraphy, composition, authigenic elements, and diagenetic environments.
  • Discussing the concept of rock typing, various schemes for categorizing rocks, and analyzing uncored reservoir sections.
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
  • SEM/EDX/XRD images and plots and comparison with FMI and other methods
  • References and further reading on petrography, petrophysics and reservoir quality
