The problem of high water cut in the products of horizontal wells

Background . The production of oil and gas by horizontal wells, despite all its advantages, is subject to exploratory operational complications. At the final stage their development, such fields become hard-to-recover reserves. Production often associated with a high water cut, significant drop in reservoir pressure, precipitation asphaltene deposits. Aim To analyze problem early indication flooding wells do research on existing solutions nowadays. Materials methods dependence logarithm water-oil ratio cumulative was investigated. An analysis decline curves carried out, along graphical diagnostics evolution. Results anticipated well determined continuing linear economic limit. A graph plotted semi-logarithmic coordinates for curves. According versus time, type logarithmic coordinates. Conclusion One most problems development consists cut obtained products. data 2020, average main Russia comprises at least 85%, mass produced approaching 1:7. use water-soluble polymers waterproofing can be considered promising direction due efficiency limiting inflow vertical directional wells.
