COURSE OVERVIEW:

This course covers all key aspects of production logging and reservoir monitoring in cased-hole wells. It explains the principles, capabilities, and limitations of production logging tools and reservoir monitoring measurements and shows how to design data acquisition programs that evaluate wellbore and reservoir behavior in line with field development objectives.

Participants will learn the nomenclature used in cased hole data acquisition, the importance of depth control, and the range of production logging tools and measurements used in oil and gas wells. The course explains inflow performance concepts, holdup measurements in multiphase flows, and the interpretation of two-phase and three-phase flow regimes, including crossflow and uneven depletion. It also addresses the use of dual choke methods to estimate productivity index and discusses why and how reservoir monitoring logs are run, including cased hole resistivity and modern pulsed neutron tools, with emphasis on integrating these data for reservoir management decisions.

COURSE OBJECTIVES:

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

• Explain the role of production logging and reservoir monitoring in field development and reservoir management.
• Describe the main nomenclature and terminology used in cased hole data acquisition and production logging operations.
• Understand the importance of accurate depth control in cased hole logging and identify methods for achieving and verifying depth control.
• Describe the principles and applications of the main production logging tools and measurements in oil and gas wells.
• Explain the basic concepts of inflow performance and multiphase flow and how they are reflected in production logging data.
• Interpret holdup measurements in three phase flows at a practical level and relate them to flow regimes and phase distribution.
• Understand conceptual equations and relationships applied in multiphase flow regimes and how they influence production log interpretation.
• Recognize the causes and implications of uneven depletion and crossflow between layers and identify how these effects appear in production logging data.
• Describe the use of two chokes to estimate productivity index and the concept of running production logs under different flow conditions.
• Interpret production logs in simple vertical and horizontal wells.
• Explain why reservoir monitoring logs are run and describe the main reservoir monitoring tools and their uses.
• Describe the principles and applications of cased hole formation resistivity measurements behind casing and modern pulsed neutron generator tools.
• Design simple data acquisition programs for production logging and reservoir monitoring that are aligned with specific field development and reservoir surveillance objectives.
• Integrate production logging and reservoir monitoring data with other subsurface information to support decisions on well interventions, workovers, and reservoir management strategies.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures and discussion sessions, as well as case studies, will be managed to maximize the amount and quality of information, knowledge, and experience transfer. 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 learning. 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.
