Multi-barrel well completion is an effective means of increasing the efficiency of hydrocarbon field development

In the oil industry, there is a reduction in carbon emissions into the atmosphere due to the abandonment of the installation of several steel casing strings and cement on the surface of the well. Instead, preference is given to a multi-sided casing joint deep in the production well. Operators are also reducing materialized and generated carbon sources in the underwater environment by eliminating the installation of additional components of the underwater mining system, such as underwater umbilicals, risers and flow lines, which require specialized underwater construction vessels. These steps are aimed at reducing the negative impact on the environment and improving the efficiency of oil production.
