Abstract

The E-xy reservoir, one of the major contributors to Badak gas production, was simulated using Intercomp's 2-component Implicit Flow Model (IFM).

The model simulates a gas condensate reservoir in which the reservoir wet gas phase is represented as a mixture of non condensable dry separator gas and vaporized liquid.

A PVT program is used to pseudoize the hydrocarbon components wet gas to a 2-component mixture with PVT properties calculated for input to the reservoir model.

With all of the basic input data, performance calculations were initiated by allowing each well to produce its designated known volume over the entire history of the reservoir. The known values of gas production have been used as input for the calculations, while reservoir pressure performance, field and individual well condensate production and water cut are the primary matching parameters. The well test data available were also matched in order to have better well productivity calculations. By considering the field operating condition in Badak field a prediction was run for a twenty-year period.
