Sažetak
Drill-in fluids become more widespread in their use recently primarily due to the increase of horizontal and multi-lateral drilling, the increase in open hole completions, and the potential for much greater production. The use of fluids that cause minimal formation damage can result in dramatically improved production, because most reservoirs are sensitive to any fluids other than those contained in them naturally. A variety of fluids can be used as drill-in fluids, including water-, oil- and synthetic-base fluids. The selection of the most appropriate drill-in fluid depends not only on potential formation damage mechanisms, but also on the type of formation to be drilled and the completion method to be used. Temperature, density and known drilling problems also must be considered. Design criteria and available drill-in fluids used world-wide, are presented in this paper.
