Reduction of productive horizons negative impact on reservoir properties is a key task when drilling wells. The quality of the primary opening impacts not only the duration of non-stop production rate but also the quality of the extracted hydrocarbon resources. At the moment, the industry has developed standard approaches to reservoirs properties preservation: hydrocarbon-based solutions, drilling at depression or at controlled pressure, well cleaning by air, etc. But the above technological solutions are characterized by significant disadvantages: the necessity of using additional equipment and personnel, significant investments. It is possible to maintain the effectiveness and eliminate the disadvantages of standard approaches by digital technologies application. The authors of the article present the process of optimizing the composition of a biopolymer potassium chloride drilling mud and demonstrate the results of the new solution filtration studies. The computational and laboratory experiments results prove reduction of washing liquid cost, increase of permeability restoration coefficient, decrease of the skin factor and flow rate potential growth.
