Abstract

Initial oil saturations have been obtained from Leverett Jfunction versus water saturation for Kizelovian sediments. History matching and forecasting data are indicative of the degree of match between predicted and actual field production data. Geological and fluid flow models have been created for carbonate sediments of the Kizelovian producing interval considering Leverett J-function versus water saturation. Historical production data for the Kizelovian production zone have been used to history match model parameters. Reservoir simulations were run to predict reservoir production performance after drilling of four horizontal sidetracks. Cumulative oil production by the end of field development period has been estimated at 99 000 tones with oil recovery factor of 0.270.

Key words:

geological and reservoir simulation model, residual oil saturation, pay zone, Kizelovian horizon, formation, structural framework, geological cross section, oil-water contact, history matching, critical water cut, mobile oil reserves.
