About the Course

Petrophysics is the physical and chemical study of rock properties and fluids. Petrophysical analysis workflows are fundamental to oil & gas subsurface formation evaluation. Common petrophysical properties include shale volume, porosity, water saturation, and permeability. Petrophysical tasks highlight locating the reservoir, detecting hydrocarbons, distinguishing oil from gas, and evaluating hydrocarbons in place. The outcome of the petrophysical evaluation is a well-profile development that identifies the key intervals and distinguishes between pay and non-pay zones.

This 5-day interactive Petrophysical Properties training course will highlight the importance of data integration from various sources to address complex reservoir evaluation and productivity challenges experienced throughout the full hydrocarbon asset life cycle. Delegates will experience a variety of data sources, fundamentals of reservoir characterisation, and methodologies of integrating key information. It combines theory with practical exercises to give delegates a working knowledge of how integrating available data at various scales can evaluate reservoir quality and heterogeneity and improve the productive potential to maximise the efficiency and recovery of hydrocarbons.

It will highlight principles of rock and reservoir properties, the value of different data sources and purposes of data acquisition for reservoir analysis, integration of core and log data to characterise flow units and reservoir properties. Furthermore, this training program provides hands-on experience using field examples to evaluate complex reservoir conditions and develop practical acumen regarding common pitfalls of data acquisition, interpretation, and presentation of results.

Core Objectives

The delegates will achieve the following objectives:

• Understand various sources of data and the purpose of data acquisition
• Know the role of routine and special core analysis in reservoir characterisation
• Deduce reservoir properties from log interpretation and core analysis
• Integrate reservoir and well data to provide an evaluation of the reservoir and characterise flow units
• Know how to avoid common pitfalls of data acquisition and analysis

Training Approach

This training course is a participatory learning experience that is both hands-on and interactive. It provides the delegates with many opportunities to advance their opinions and ideas. It will be facilitated in a supportive environment, ensuring that the concepts introduced during the course are well understood and comprehended, utilising various proven adult learning techniques to ensure maximum understanding, comprehension, and retention of the information presented.
