The article gives a brief review of currently used reagents. Technological advantages of Kometa-Meteor polymer composition of domestic production are shown, expressed in possible economic benefit, which consists in reduction of expenses for intensification of fluid inflow and preparation of drilling mud. A number of problems encountered in sinking and drilling wells are considered, and the advantages of drilling fluids treated with Kometa-Meteor for such conditions compared to other fluids are shown. It concludes with a review of the pricing of existing reagents.
