Beschreibung
This book focuses on cement bond logs (CBL) as a critical tool for ensuring long-term well integrity. It covers key topics such as acoustic fundamentals, factors influencing cement bond and variable density log (CBL/VDL) readings, cement bond logs evaluation, and methods to address the microannulus effect, which can lead to misleading log results. It also includes a discussion of waveforms, particularly in relation to VDL readings. The book explores how both conventional sonic and new ultrasonic technologies capture and interpret waveforms to assess variations in cement bond integrity. Practical case studies are provided to demonstrate how sonic and ultrasonic CBL interpretation can improve decision-making in assessing well integrity. Additional guidance is provided on evaluating log quality, supervising and witnessing logging operations, and comparing different logging tools.
Cement Bond Logs: Guidelines and Interpretation serves as an essential resource for engineers and researchers seeking to improve wellbore integrity through practical and accurate cement evaluation.
- Describes cement bond logs evaluation, supervision and guidelines for logging and interpretation;
- Emphasizes the crucial role that cement bond logs play in maintaining well integrity;
- Provides case studies with interpretations of practical types of logs.
