Key words: regional integrated modeling, multiphase hydrocarbon flow, oil and gas transportation.
The paper considers the method of hydraulic calculations in horizontal and inclined pipelines actually applied within the frames of regional integrated modeling, as well as in boreholes of production and injection wells. The authors have performed the comparison of the results achieved using this method with the analogous results achieved using Pipesim software. The average discrepancy between the input data in both software makes less than 1%. Basing upon the example of Samaraneftegaz JSC it was illustrated that the speed of calculations using this applied method is 20 times higher than the speed of analogous calculations through Pipesim 2003, that opens new possibilities in automated solution of optimization targets within the production company (search of optimum network lengths, selection of pipe diameters, connection of new wells and licensed areas).
