1. A computer-implemented method, comprising:
determining a gas-oil rate (GOR) for an oil well measured before water injection;
determining a measured water cut (WC) for the oil well;
determining an initial solution GOR for the oil well;
determining a corrected WC for the oil well based on a function comprising a difference between a ceiling value and a ratio of the GOR relative to the measured WC, and the initial solution GOR;
presenting, in a user interface based on the corrected WC for the oil well, suggestions for implementing improvements in production at the oil well, comprising suggestions for changes to parameters used in drilling at the oil well;
receiving, through the user interface, user selections of the suggestions for changes to parameters; and
implementing, using the user selections to parameters, changes in drilling at the oil well.
