This course covers knowledge of water-based, oil-based drilling-fluids chemistry, formulation, testing procedures, and basic skills of drilling fluids engineering. Clay chemistry, rheology, system maintenance (including weight and solids control), contaminants and contaminant removal techniques, mud hydraulics, and special drilling problems related to drilling fluids.
WHO SHOULD ATTEND
Entry Level Drilling Personnel, Drilling Engineers, Geologists, Mud Engineers, Mud Loggers, Engineering and Geological Technicians, Drilling Supervisors, Service and Support Personnel.
BENEFITS OF THE COURSE
At the end of this course the participants will be able to do the following:
Gain working knowledge of popular drilling fluid systems and understand daily mud check report
