Selection of the design for water shut-off jobs in the software system RN-REST

Authors: A.M. Ilyasov, I.Yu. Lomakina, V.A. Strizhnev (RN-UfaNIPIneft LLC, RF, Ufa)

Key words: water shut-off jobs, WSO design, workovers.

The process of planning water shut-off (WSO) jobs in oil producers is based on the selection of optimum WSO design that is characterized by the lowest water cut after the job along with maximum incremental oil rate. A software product that makes possible the evaluation of different WSO jobs effectiveness for vertical wells in sandstone reservoirs is presented in the paper along with the current directions of its development. WSO Design modulus is based on the software system RN-REST and it is currently implemented in producing affiliates of Oil Company Rosneft. It covers many types of workovers that include isolation materials and allows loading all the data necessary for calculation in automatic mode. These features make the modulus a convenient instrument to create a design of WSO jobs on Oil Company Rosneft oilfields.
