COURSE OVERVIEW:

This course provides a comprehensive and practical coverage of reservoir fluid sampling and laboratory analysis, from planning and acquisition in the field through to interpretation and application of the results in reservoir engineering and management. Participants will learn how to design and execute representative fluid sampling programs in exploration, appraisal, and development wells, using surface and downhole techniques under different operating conditions.

The course explains the principles and limitations of common sampling methods (bottom hole samples, downhole sampler tools, separator and stock tank samples, recombination techniques, and special sampling situations such as multiphase flow and high gas oil ratios). It then covers in detail the suite of laboratory analyses applied to reservoir fluids, including PVT studies, compositional analysis, phase behavior characterization, contamination assessment, and routine quality checks needed to ensure reliable results.

Strong emphasis is placed on data quality, representativity, avoidance of contamination and phase changes, and on how to translate laboratory outputs into engineering properties and models used in volumetrics, material balance, simulation, well performance, and production allocation. Realistic examples and case studies illustrate typical problems such as gas breakout, mud filtrate contamination, wax and asphaltene issues, and unstable test conditions, together with mitigation strategies and best practices. By the end of the course, participants will be able to plan, supervise, and evaluate reservoir fluid sampling and analysis programs and use the results confidently in reservoir and production engineering applications.

COURSE OBJECTIVES:

After completion of the course, the participants will be able to:

• Explain the role of reservoir fluid sampling and analysis in field appraisal, development planning, and reservoir management.
• Distinguish between different types of reservoir fluids (black oil, volatile oil, gas condensate, wet gas, dry gas) and understand how this affects sampling and analysis requirements.
• Describe the main downhole and surface sampling techniques and the conditions under which each is most appropriate.
• Plan fluid sampling programs for exploration, appraisal, and development wells, including objectives, tools, depths, volumes, and quality control checks.
• Recognize the main causes of sample contamination and loss of representativity, including mud filtrate, drilling and completion fluids, and improper handling.
• Apply best practices for obtaining representative downhole samples using wireline formation testers and downhole bottles.
• Evaluate the quality and representativeness of surface samples from separators, test lines, stock tanks, and multiphase flow lines.
• Describe the standard PVT laboratory workflow from sample reception, validation, and recombination through to routine and special PVT tests.
• Interpret key PVT results (formation volume factors, solution gas oil ratio, bubble point pressure, dew point pressure, viscosity, Z factor) and their relevance to reservoir and production engineering.
• Understand the basics of compositional analysis and equation of state modeling, and how laboratory data are used to tune and validate fluid models.
• Identify and assess issues related to wax, asphaltenes, scale, hydrates, and other flow assurance risks arising from fluid analysis.
• Use fluid sampling and analysis results in volumetric calculations, material balance, well deliverability modeling, and reservoir simulation input.
• Review and challenge fluid sampling and PVT study proposals, laboratory reports, and contractor deliverables to ensure technical adequacy.
• Communicate sampling objectives, data quality issues, and analysis results effectively to reservoir, production, and facilities teams.

TARGET AUDIENCE:

• Reservoir engineers and reservoir engineering technologists
• Petroleum and production engineers involved in well testing and production operations
• Petrophysicists and formation evaluation specialists working with fluid data
• Well test and well intervention engineers are responsible for sampling operations
• Process and facilities engineers who use fluid properties for equipment design and operation
• Laboratory coordinators and PVT study focal points
• Asset team members and technical managers who review sampling and PVT programs and reports

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive but practical and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material through PowerPoint equipped with necessary animation, learning videos, and general discussions will be provided.

The course participants shall be evaluated before, during, and after the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants who complete at least 80% of the total attendance time requirement.
