Investigation methods of protection from the complications during the production in the final stage of field development

In the article, based on the data of the fields in the final stage of exploitation, the most important complications that occurred during the production period and the methods of preventing these complications in the modern period were investigated. In particular, the methods of preventing of the sand plug and flooding, which are the main problems in this type of fields, were investigated and the significance of these methods of selective control against flooding was investigated, the most successful ones among these methods were shown, the hardening of the bottom hole against sand plug and the use of sand control screen in modern times were considered, in the hardening of the bottom hole the use of resin-containing components is mentioned.
