Claim 16:
17. A system comprising:
one or more processors configured to perform operations comprising:
generating (i) a water-oil-ratio with respect to time (WOR) dataset for a wellbore, and (ii) a time-derivative dataset (WOR′) of the WOR dataset;
determining, based on the WOR dataset and the WOR' dataset, a first type of water breakthrough;
generating, based on pressure data from the wellbore, a plot of time-derivative pressure data with respect to time (P′);
determining, based on the P′ plot, a second type of water breakthrough;
correlating the first and second type of water breakthrough; and
determining, based on the correlation, whether to perform a water treatment for the wellbore.
