Study of Innovative Water-Insulating Composition Based on Urea-Formaldehyde Resin

The world's oil companies currently produce an average of three tons of water for every ton of oil extracted from depleting reservoirs. In Azerbaijani fields, this figure is 15 tons of water per 1 ton of oil. During repair and isolation work in production wells, it is necessary to use such water-proofing materials that selectively reduce the amount of water produced from the well, without reducing the oil production rate. the problem arose of creating a polymer cement composition based on urea-formaldehyde resin using an available catalyst (hardener) that eliminates the above disadvantages. Firstly, it was necessary to expand the temperature range, in connection with this, an aqueous 2% hydrochloric acid (HCl) solution was chosen with the addition of 5.0 to 13.0 % by weight of urea-formaldehyde resin, for temperatures from 20÷75 °С.
