Summary

This course provides an in-depth examination of well construction technologies and the reservoir characteristics necessary for designing horizontal and multibranch wells. Participants will gain a comprehensive understanding of specialized drilling strategies, including horizontal drilling, extended reach drilling, underbalanced drilling, and coiled tubing drilling. The course will also cover geosteering techniques and the use of special downhole tools. Additionally, participants will explore methods for stimulation and sand control specifically tailored for horizontal and extended reach wells, equipping them with the knowledge and skills needed to effectively manage these complex drilling operations.

Business Impact: Participants will learn to design and execute complex wells that increase reservoir contact, improve productivity, and reduce drilling risks. With skills in geosteering, stimulation, and advanced completions, they’ll enhance recovery, lower costs, and optimize field development outcomes.
