Radius of investigation and condensate banking evaluation of gas condensate reservoirs

In this work, we propose a method to calculate the condensate bank size and the radius of investigation of a well test in a gas condensate reservoir. The work was purely based on numerical flow simulation. We performed some basic multiphase flow simulations in a gas condensate reservoir. Radius of investigation and condensate bank size were both calculated numerically and compared to the single phase radius of investigation formulae. On the basis, a new formula is developed for condensate bank size estimation. We show that this formula can be used to predict the radius of investigation and the condensate bank size by adding a weighting factor which can be determined numerically to the single phase formula.
