Key words: Drilling Fluid, Quality of Hydrocarbon-Bearing Formation Exposing, Assessment of Drilling Fluid Efficiency, Cumulative Oil Production, Weighted Average Depression.
The article deals with considering of the experience of the application of experimental Petro Com S Drilling Fluid developed by LLC «ISC «PetroEngineering» and the simple field methodical approach to the assessment of its effectiveness in comparison with the base solution, which is widely used in the three fields of Western Siberia: Maliklyuchevoe, Las-Eganskoe and Nivagalyskoe. The essence of the proposed method is to estimate the impact of competitive fluids on formation permeability characterized by actual productivity factors, by comparing the values of the calculated cumulative oil production of experimental and base fluids at the weighted average depression in the same periods of operation of wells.
