Key words: permeability of borehole environment, filter cake, acid soluble filler, cake removal, mixture of carboxylic and amino carboxylic acids. Through the example of wells with granular reservoirs at the Arsykum field (the Republic of Kazakhstan), it is shown that the degree of influence of filtration barriers preventing inflow into the hole increases with the increase of the length of a horizontal hole. Optimization of the content and size of fractions of acid soluble fillers in drilling mud ensures mud injection whilst drilling through the formation and effective mud removal during stimulation treatment.
