COURSE OVERVIEW:

Basic open-hole tools form the foundation of formation evaluation, enabling engineers and geoscientists to characterize lithology, porosity, fluid types, saturation, and mechanical properties of the subsurface before the well is cased. This course provides a complete introduction to the primary open-hole logging tools, their operating principles, measurements, environmental corrections, conveyance systems, and applications in reservoir evaluation.

Participants will learn how each tool responds to geological formations, how logs are recorded and quality-controlled, and how the measurements integrate with petrophysical interpretation workflows. The course also introduces safety considerations, tool deployment procedures, and limitations encountered in deviated, washed-out, and complex boreholes. Real examples from clastic, carbonate, and unconventional formations demonstrate how open-hole logs guide reservoir characterization, well placement, and completion decisions.

COURSE OBJECTIVES:

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

• Understand the purpose and fundamental principles of open-hole logging.
• Identify the major categories of open-hole tools and their measurement physics.
• Describe gamma ray logging for lithology and shale-volume estimation.
• Explain resistivity measurements and their role in fluid-type determination.
• Interpret density and neutron porosity logs for formation porosity evaluation.
• Understand sonic and acoustic tools for mechanical and petrophysical analysis.
• Apply caliper logs to understand borehole geometry and its impact on log quality.
• Recognize environmental effects and apply appropriate corrections.
• Understand borehole conditions and conveyance-system constraints.
• Perform basic quality-control checks on open-hole logs.
• Integrate open-hole measurements into petrophysical interpretation workflows.
• Identify common logging challenges and operational limitations.
• Understand safety and communication protocols during logging operations.
• Prepare accurate logging summaries and interpretation-ready data sets.

TARGET AUDIENCE:

• Logging Engineers and Field Specialists
• Petrophysicists and Formation Evaluation Staff
• Reservoir and Petroleum Engineers
• Geoscientists and Wellsite Operations Personnel
• Drilling and Completion Engineers
• Junior Engineers entering the wireline and logging-while-drilling disciplines
• Anyone seeking foundational knowledge of open-hole logging tools

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, 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 will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
