The demands placed upon drilling fluids have increased dramatically over the last two or three decades. The drivers include reducing environmental impact, maximizing well productivity, accessing high temperature reservoirs, extended reach drilling, and deep water drilling. Course participants will learn about the fluid systems and additives developed to meet these demands, as well as basic introductions to drilling fluids, clay chemistry, and polymer chemistry. The molecular structure and functionality of various fluid additives is presented to gain an insight into how things work and how fluid formulations are designed to meet specific well parameters.
Upon successful completion of this course, the delegates will be able to:
- Have an understanding of the composition and properties of drilling and completion fluid systems and additives
- Gain insights into how things work, and where they do not work
- Have grounding in clay chemistry and polymer chemistry and their importance to drilling fluid design
- Have an appreciation of the importance of efficient solids control
- Acquire a background in the mechanisms of formation damage, reservoir fluid design to maximize productivity, completion fluid systems, and the field applications of completion brines.
