Geochemical Techniques for Solving Reservoir Management and Field Development Problems - GTS

Introduction

This Geochemical Techniques for Solving Reservoir Management and Field Development Problems training course addresses the technical aspects of the geochemistry applied to the exploration, appraisal, and development of hydrocarbons reservoirs, considering topics of particular importance to identify specific geochemistry features that lead to the origin of petroleum samples, deposition of source rock, hydrocarbon generation, and oil and gas migrations, important elements for the successful exploration of petroleum and gas accumulations. Geochemistry concepts are applied to investigate the source rock evaluation, oil-to-oil, oil-to-source rock correlations, and interpreting natural gas data in the exploration stages, assisting in the development and production phases, supporting reservoir continuity, production allocation, water flooding and Enhanced Oil Recovery projects. The training course provides transferring experiences applying geochemistry fundamentals to support the hydrocarbon exploration, reservoirs identification, fluid movements in large hydrocarbon basins, solving continuity and delimitation of compartments, applications to monitor waterflooding and gas flooding enhanced oil recovery projects, and to trace the sources of oil spills.

The highlights of this training course will be as follows:

• Learn the fundamental aspects and applications of geochemistry principles
• Describe the evolution of organic matter during geological history
• Understand application of production geochemistry applied to oil fields
• Describe laboratory methods including Rock–Evaluation Pyrolysis, Soxhlet extraction, Column Chromatography, Asphaltene precipitation, GC, GCMS, Head Space gas analysis, Organic Petrography using transmitted reflected and Ultraviolet light
• Review the evaluation techniques used to assess quantity, quality, maturation and depositional environments of petroleum source rocks, oil and gas prone kerogens, oil and gas generation with maturation, primary, secondary, and tertiary migration
• Discuss interpretive pitfalls

Objectives

By the end of this training course, participants will learn to:

• Interpret Rock-Evaluation pyrolysis using source rock, and reservoir fluid samples
• Understand the type and maturity of organic matter applying organic petrography, vitrinite reflectance and thermal alteration Index
• Classification of kerogens based on elemental analysis, pyrolysis, and geochemical logs
• Gas chromatography applications, gas chromatography-mass spectrometry, and source-rock generative kinetics
