Implicit express simulation modeling of multistage fracturing in horizontal wells

Authors: I.V. Kovalenko (Gazpromneft NTC LLC, RF, Saint-Petersburg)

Key words: implicit express modeling; equivalent skin factor; dimensionless pressure loss coefficient on the elliptical mode filtering.

The article describes the technology of implicit express simulation modeling of multistage fracturing in horizontal wells which minimizes the time and resources at the forecast of oil production in models with a large number of horizontal wells with multiple hydraulic fracturing. It also allows making multiple calculations in a short period of time in determining the optimum geometry of reservoir fracture and their quantity per one horizontal well. As a practical example the technology was described for Novoportovskoye oilfield that confirmed the nearness of the results that were obtained with the implicit express simulation modeling and the results that were obtained with explicitly detailed simulation modeling.
