Description

Designed for you, if you are...

• A geoscientist, petrophysicist, wellsite supervisor or reservoir engineer
• A geodata technologist involved in multidisciplinary formation evaluation and development teams engaging in explorations, appraisals, or field development activities

How we build your confidence

• The course is presented in a manner so that both beginners and experienced personnel will find the material very useful
• The content and example problems are carefully selected to teach and illustrate important concepts
• Case studies

The benefits from attending

• Understand pore pressure concepts and pressure regimes (normal, over-pressure, under-pressure)
• Recognise tools and methods for formation pressure measurement (e.g., wireline testers, LWD, DST)
• Plan formation pressure tests (tool selection, station planning, parameters)
• Interpret pressure data to determine drawdown mobility, fluid gradients, contacts, and pressure compartments
• Understand applications and job design of advanced pressure applications like MiniDST and VIT
• Build and interpret formation pressure plots to identify gradients and contacts
• Understand principles of downhole fluid sampling and contamination control
• Differentiate fluid sampling tools and techniques (single-phase, multiphase, clean-up strategies)
• Plan fluid sampling operations with focus on quality, contamination mitigation, and safety
• Validate pressure and fluid sample data (seal quality, contamination signs)
• Analyse clean-up curves and sampling logs data to assess sample contamination
• Integrate data into reservoir models and fluid characterisation workflows
• Plan a formation testing and sampling job in a team case exercise
• Review and discuss real case studies to identify decisions, challenges, and lessons learned
