This study attempts to predict post-breakthrough performance in horizontal wells as a result of water coning. The post breakthrough performance is measured in terms of the Water Oil Ratio (WOR). Correlations were developed to predict the WOR, time to breakthrough and the critical oil production rate in horizontal wells. The reservoir studied was modelled using a 3D simulator (ECLIPSE100). PVT and Relative permeability data from literatures were used in modelling the reservoir. A one well model was simulated by setting up a ‘base case’ scenario of reservoir parameters, the WOR from this base case was observed. Sensitivity analysis was then carried out by varying each of the reservoir parameters and production rate independently. Regression analysis was done to develop correlation between the height above/below the perforations and the WOR. The developed correlations compared favourably well with the existing ones.
