Well Testing in Gas-Condensate Reservoirs
Abstract/Contents
- Abstract
- Gas-condensate reservoirs differ from dry-gas reservoirs. Understanding of phase and fluid flow behavior relationships is essential if we want to make accurate engineering computations for gas-condensate systems (e.g., well testing, estimating reserves and predicting production trends). Condensate dropout occurs in the reservoir as the pressure falls below dew-point, as a result of which, the production decreases significantly and the condensate bank formed is also unrecoverable. Hence, the condensate saturation and liquid buildup is very significant in gas-condensate reservoirs. However, it has been observed that the saturation buildup across the reservoir is much more than the maximum equilibrium saturation given by the equilibrium phase behavior of the condensate fluid. This study aimed at understanding the multiphase flow behavior in gas-condensate reservoirs and, in particular, investigated the factors that lead to such high saturation buildup in the reservoir. Changes in the fluid composition due to liquid dropout have also been investigated. In particular, we studied the effect of critical condensate saturation and shapes of relative permeability curves on flow and saturation buildup fluid.
