COURSE OVERVIEW:

Cement Evaluation from Basics to Advanced Interpretation is a specialized program designed to provide engineers with the analytical skills required to verify the integrity of the primary well barrier. In the lifecycle of a well, the quality of the cement sheath is the most critical factor in ensuring zonal isolation and preventing hazardous fluid migration between geological layers. This course moves from the fundamental physics of acoustic measurements to the complex interpretation of the latest generation of ultrasonic imaging tools.

The scope of this training includes a detailed breakdown of how sonic and ultrasonic waves interact with the casing, cement, and formation. Participants will learn to differentiate between a solid cement bond, micro-annuli, and the presence of gas or liquids behind the casing. By mastering the interpretation of Cement Bond Logs (CBL) and Variable Density Logs (VDL), attendees will gain the confidence to make data-driven decisions regarding the safety and readiness of a well for production or stimulation activities.

Coverage extends to the integration of mechanical integrity tests with electronic logging data to provide a holistic view of wellbore isolation. The course addresses modern challenges such as evaluating cement in thin-wall casings, high-density slurries, and contaminated environments. Through the analysis of real-world log examples and complex case studies, participants will develop a sharp eye for identifying channel formation and bond degradation, ensuring that remedial squeeze jobs are only performed when technically necessary and with high precision.

COURSE OBJECTIVES:

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

• Explain the physical principles of acoustic wave propagation in a cased-hole environment.
• Distinguish between the various types of waves including compressional, shear, and Stoneley waves.
• Interpret Cement Bond Logs (CBL) to determine the compressive strength of the cement.
• Analyze Variable Density Logs (VDL) to identify the quality of the cement-to-formation bond.
• Recognize the "Chevron Pattern" and other diagnostic signatures in acoustic logs.
• Differentiate between a genuine poor bond and the presence of a micro-annulus.
• Evaluate the benefits and limitations of ultrasonic imaging tools versus traditional sonic tools.
• Identify channeling and gas cut cement using advanced radial imaging techniques.
• Assess the impact of casing size, weight, and fluid type on log response accuracy.
• Integrate cement evaluation data with open-hole logs for comprehensive zonal isolation analysis.
• Perform quality control checks on logging data to ensure tool calibration and reliability.
• Recommend remedial action plans based on the interpretation of isolation scanners.
• Justify the selection of specific logging suites for various wellbore conditions.

TARGET AUDIENCE:

Petrophysicists, Drilling Engineers, Completion Engineers, Well Integrity Specialists, and Operations Managers involved in well construction and intervention.

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.
