Annotation:
A method is proposed for assessing the optimal concentration of organic-silicon resin in a solution injected into the bottom hole zone of the formation in order to limit sand manifestations during the development of weakly cemented productive formations. The optimality criterion is the maximum well flow rate. The method is based on the results of laboratory experiments on the effect of resin concentration on the strength of rock adhesion and the phase permeability of formation fluids. An example of the method application is given.
