Course Summary

Well logs provide an intricate documentation of geological formations penetrated by a borehole. These records represent critical and valuable data collected at various stages of a well's lifecycle, crucial for determining the petrophysical characteristics that ascertain the reservoir's economic worth. Consequently, the methodologies applied in analyzing and interpreting well logs are fundamental for the identification of hydrocarbon extraction potentials.

This Advanced Well Log Interpretation training course is meticulously designed to cover the entire spectrum of well logging, from the fundamental principles and tools involved in well log interpretation to the intricate techniques required for analyzing complex geological formations. Starting with the basics of well logging and petrophysical properties, the course quickly progresses to detailed sessions on electrical, sonic, and nuclear loggings, offering deep insights into each method's unique applications and challenges. Participants will then explore the cutting-edge realms of Nuclear Magnetic Resonance (NMR), Production Logging (PL), and Logging-While-Drilling (LWD), which are pivotal for real-time formation evaluation and optimizing drilling operations. The curriculum culminates in integrated data interpretation strategies and advanced topics, including log applications in complex carbonate reservoirs, shaly sands, and shale oil/gas formations, enriched with interpretation case studies. This comprehensive approach ensures that participants are well-equipped with the knowledge and skills to tackle the challenges of modern well log interpretation, making it an essential training course for professionals aiming to excel in the evolving landscape of oil and gas exploration and production.
