Lesson 4 • Core Report Writing

Guides compilation of a professional core description report with figures and interpretations. Report quality directly affects reservoir characterization and field development decisions.

Lesson 1 • Reflected Light and Opaque Mineral Analysis

Introduces reflected light microscopy for ore minerals, pyrite, and organic matter. Opaque mineral assemblages provide redox and thermal maturity information.

Lesson 2 • Transmitted Light Microscopy

Teaches plane-polarized and cross-polarized light techniques for mineral identification. Optical properties such as birefringence and extinction angle distinguish key minerals.

Lesson 3 • Sandstone Petrography

Applies point-counting and framework analysis to characterize sandstone composition and diagenesis. Results feed directly into reservoir quality and provenance interpretations.

Lesson 4 • Thin Section Preparation

Covers sample impregnation, cutting, grinding, and polishing to produce quality thin sections. Preparation quality directly controls the reliability of petrographic observations.

Lesson 1 • Formation Water Analysis

Explains sampling, preservation, and ion analysis of formation water samples. Water chemistry identifies reservoir connectivity, scaling risk, and diagenetic environment.

Lesson 2 • Mud Gas Monitoring and Interpretation

Covers gas detector operation, chromatograph output, and hydrocarbon ratio analysis. Gas data provide real-time reservoir indicators and source rock maturity proxies.

Lesson 3 • X-Ray Diffraction for Mineralogy

Covers XRD sample preparation, diffractogram interpretation, and clay mineral quantification. XRD results complement petrographic observations and constrain diagenetic models.

Lesson 4 • Stable Isotope and Fluid Inclusion Analysis

Introduces oxygen, carbon, and strontium isotope applications and fluid inclusion microthermometry. These tools constrain paleofluid temperatures and diagenetic fluid sources.

Lesson 1 • Porosity and Fluid Saturation Estimation

Covers porosity derivation from log combinations and water saturation from Archie equations. Lab-measured porosity and fluid data validate log-derived petrophysical parameters.

Lesson 2 • Core-to-Log Depth Matching

Explains depth shift procedures aligning core measurements to log depth reference. Accurate depth matching is essential before any core-log integration or petrophysical study.

Lesson 3 • Formation Evaluation Reporting

Guides preparation of integrated formation evaluation reports combining log and lab data. These reports are the primary technical deliverable for reservoir development planning.

Lesson 4 • Lithology Identification from Logs

Applies crossplot techniques and log signatures to identify formation lithology. Log-based lithology is calibrated against core and cuttings descriptions from the lab.

Lesson 1 • Fracture Characterization and Modeling

Combines core fracture logs, image logs, and geomechanical data for fracture network modeling. Fracture models are critical for naturally fractured reservoir production forecasting.

Lesson 2 • Exploration and Development Recommendations

Translates reservoir characterization findings into actionable exploration and development recommendations. Students practice communicating technical conclusions to non-specialist audiences.

Lesson 3 • Depositional Environment Reconstruction

Integrates core, petrography, and log data to reconstruct depositional environments. Environmental models control reservoir geometry, connectivity, and heterogeneity predictions.

Lesson 4 • Diagenesis and Reservoir Quality Prediction

Links diagenetic history from petrography and geochemistry to reservoir quality distribution. Predictive diagenetic models guide well placement and completion design.
