Construction of water injection wells

The company has experience in the construction of water injection wells on a turnkey basis at the Lachielsky block of the Yaregskoye field. These wells are not connected to the reservoir pressure maintenance system, but are built for the environmentally friendly disposal of wastewater that is generated during the oil extraction process by the shaft method. A distinctive feature of the design of such wells is the running of separate parts of the casing string, consisting directly of the dead casing string and the filter, which is installed in the absorbing part of the target horizon. In this case, only the blind part is cased by installing an annular packer and a staged cementing collar.
