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 One: 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 Two: 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 Three: 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 Four: 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 Five: 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.
