Why Choose this Training Course?

This Petrographic and Reservoir Quality Analysis of Siliciclastic and Carbonate Reservoirs training course focuses on some of the most important challenges facing the exploration of oil/gas reservoirs, that’s the types of controls on reservoir quality of siliciclastic and carbonate reservoirs.

Innovative petrographic analyses will permit to:

Improve the knowledge of petrographic & diagenetic markers for reservoir quality assessment of exploration targets
Understand the differences between siliciclastic and carbonate rocks in terms of depositional environments, provenance, initial porosity and porosity evolution of reservoir sediments during burial
To help choose the best analytical petrographic analyses on core samples, cuttings and outcrop rocks to optimize the completion of geological projects for a certain exploration play

What are the Goals?

By attending this Petrographic and Reservoir Quality Analysis of Siliciclastic and Carbonate Reservoirs training course, you will learn to:

Understand the Petrographic techniques for the study of sedimentary rocks
Distinguish between Siliciclastic & Carbonate sediments in terms of main controls on reservoir quality
Identify the potential Petrographic/Diagenetic markers for Paleo-Environmental and Diagenetic Reconstructions
Implement innovative analytical programs for ongoing or future geological projects
Correlate sedimentary sequences by means of Petrographic results
Build a multi-well Petrographic/reservoir quality model for regional exploration projects

Who is this Training Course for?

This Petrographic and Reservoir Quality Analysis of Siliciclastic and Carbonate Reservoirs training course is suitable to a wide range of professionals but will greatly benefit:

Sedimentary geologists of service and oil companies
Junior to mid-level geologists carrying out rock-based geological projects
Sedimentologists who need to be conversant on reservoir quality concepts
Petrographers of small and large oil-industry organizations
PhD students in sedimentary geology of academic institutions

Daily Agenda

Day 1: Sandstone Petrography

Why do we use Petrography?
Thin sections and staining methods
Petrographic microscope
Texture: Grain size, sorting, roundness, grain contacts, matrix content, textural and mineralogical maturity
Detrital composition: Main framework components. Optical/physical properties of most important minerals of siliciclastic rocks under PPL and XPL
Sandstone classification, ternary plots (e.g., Pettijohn, 1987), visual estimation of % of minerals (comparison charts), quantitative analysis/point count (point count table & type of software for data collection, e.g., Petrog vs. Digital Image Analysis), QFL, provenance & tectonic settings
Definition of matrix and pseudo-matrix
Work at the microscope

Day 2: Diagenesis, Porosity and Associated Microscopy Analysis

Compaction and authigenic components (e.g., silica cementation, carbonate cementation, clay minerals, pyrite, hematite etc, hydrothermal cementation); chemical & mechanical stability of minerals
Diagenesis and diagenetic environments
Porosity types in sandstones & microporosity: Primary porosity, secondary dissolution pores and fractures. Visual estimation from TS photos, charts
Reservoir quality assessment. Relationship between rock composition, cementation, and poro-perm. Evolution (e.g., clay cementation vs. carbonate cementation)
Core samples and Cuttings TS descriptions/analysis tied to wireline logs
Concepts of SEM, EDAX, XRD, QEMSCAN analyses. Why use SEM magnification, structure of clays, description of matrix, chronology of diagenetic events, microporosity and microporosity types?
Data integration (sedimentology & CA data). Poro-perm plots and practical examples

Day 3: Introduction to Carbonate Reservoirs

Components of limestones, non-skeletal particles, skeletal particles (e.g., algae, mollusks, brachiopods, echinoderms, forams), contribution of algae & bacteria to limestone production (e.g., stromatolites). Table of taxa vs. mineralogy
Carbonate matrix (also at SEM magnification); Classification of limestones (Dunham & Embry & Klovan), definition of crystalline rocks by crystal size; Depositional environments/petro-types
Authigenic components (non-ferroan vs. ferroan calcite, dolomite, anhydrite, hydrothermal cementation)
Thin section descriptions and modal data
Work at the microscope

Day 4: Diagenesis, Porosity & Reservoir Quality

Carbonate diagenesis: Aggrading neomorphism, compactional fabrics (e.g., pressure solution), marine diagenesis, intertidal-supratidal, subtidal cementation, marine dissolution, discussion of marine cements, meteoric diagenesis, vadose and phreatic zones, calcite spar and its origin
Depositional vs. diagenetic porosity in carbonates, dissolution processes (e.g., meteoric vs. burial)
Poro-perm characteristics of carbonate rocks
Reservoir quality of carbonate rocks, by texture, diagenesis controls and structural deformation
Practical examples, exercises and work at the microscope

Day 5: Dolomitization & Associated Microscopy Analyses. Final discussion

Dolomitization, dolomite textures, xenotopic vs. idiotopic dolomites, saddle dolomites, hydrothermal dolomite structure. Exercises. De-dolomitization of calcite, silicification of calcite (example from oil reservoirs), other cement (e.g., siderite)
Dolomite texture vs. petrophysics, dolomitization models (Sakha/evaporation, mixing zone, seepage reflux, burial)
SEM analysis of carbonate phases, chemistry of minerals through EDX traces, XRD, CL analysis (oxidizing vs. reducing environments)
Poro-perm characteristics of dolostones
Exercises and work at the microscope
Final discussion, examples of oil/gas reservoirs & training material

Certificate

On successful completion of this Training Course / Online Training Course, a PetroKnowledge Certificate / E-Certificate will be awarded to the delegates.
