A Prediction of Water Breakthrough Time of Horizontal Wells in Gas Reservoirs with Bottom Water

Abstract:

Based on the theory of porous flow, a study on prediction of water breakthrough time of horizontal wells in a homogeneous gas reservoir with bottom water is presented. This paper derives water breakthrough time formula of horizontal wells in a reservoir with bottom water drive. In the formula many factors are taken into account, such as height of water avoidance, gas-water mobility ratio, irreducible water saturation, residual gas saturation, etc. Case study indicates that for a horizontal gas well with constant production rate, the water breakthrough time is proportional to the height of water avoidance.
