CBM Course

This course is based on technical fundamentals of CSG and how they relate to production. The focus is on the practical aspects of developing the CSG resource. The course begins with comparing CSG with conventional oil and gas. It is critical in understanding where the differences lie and what is important. Fundamentals are explained and how they relate to developing the resource. The importance of seismic and identification of “sweetspots” are explained. Well designs and production operations are discussed in depth. The course is interlaced with the instructor’s practical experiences enabling the participants to understand the practical aspects in unlocking the resource. The instructor encourages participants to bring to the course examples of challenges they face with their projects.
