Examining the effects of different types of drilling fluid additives on preventing fluid-loss and selecting the appropriate fluid to maximize productivity and enhance its quality

Drilling mud is an important fluid in drilling operations and is directly related to drilling problems. If the drilling mud does not have the proper properties, it would be difficult to drill in the drilling operation. Thus, the need to use fluids limiting operational problems, and improving drilling and saving time and money is clearly felt. Moreover, today the phenomenon of fluid-loss of drilling into cracked formations has become a major challenge for the drilling industry. Heavy costs such as loss of drilling time, excessive consumption of materials, unprofessional control techniques and low productivity are of the problems needed to cope with this problem. The study type is applied and descriptive-analytic regarding research method conducted in case study design. Data collection method is documentation and library study. The study first explained the types of drilling mud and its additives and its impact on drilling quality. Then, it was concluded that knowing the type of drilling fluid and its additives and its choice to reduce the cost of drilling and increase the efficiency have a great impact on the drilling quality. Moreover, the effect of polymer additives, nanocomposites and industrial powders on the reduction of loss was investigated showing that the addition of nanocomposites and polymeric materials reduces the thickness of sludging and fluid loss and also increases the viscosity of drilling mud and can be very effective in increasing productivity and reducing costs.
