This course addresses basic concepts of the latest developments in drilling fluids technology. Student will learn the key concepts of drilling fluids function, develop an understanding of the physical and chemical properties of drilling fluids from field standpoint, and gain some practical insight into methods and materials currently used to control drilling fluid properties and problems. Participants will then learn how implement this knowledge to aid in the design, maintenance, and development of an efficient fluid system for a given drilling scenario. Some diagnostic exercises will be given to identify fundamental drilling fluid problems. Various drilling systems will be introduced and the advantages and disadvantages of different systems will be discussed.
