Performance Predictions for Gas-Condensate Reservoirs

Summary This paper considers some reservoir engineering aspects of the performance of gas-condensate reservoirs that are important for commercial exploitation: calculation of producible fluids, material-balance computations, well deliverability predictions, estimates of the size of the two-phase zone, and saturation changes during the buildup period. Two production modes (constant pressure and constant rate) are considered. Both transient and boundary-dominated periods are examined. Extrapolation of results derived from data above the dewpoint pressure to conditions below the dewpoint pressure is discussed.
