In order to increase the scenarios of using valves for flushing, we have developed the ARP Inject PRO valve equipped with a plug that is soluble in the layer environment. This technical solution makes it possible to descend the layout with high-pressure flushing through the construction element “shoe”, preventing non-target fluid flow through the valve. After the descent of the completion layout and carrying out all the necessary work in the well, the plug dissolves under the influence of the layer environment (extracted fluid) after that it is possible to conduct well flushing cycles in a normal mode. At the same time, there is no need to inject acid to dissolve previously used plugs, it significantly reduces the cost at the initial stages of a well start . At the present time, technical solutions that have been implemented, allow a well to keep tightness for more than 240 hours
