1. A method, comprising:
conveying a straddle packer assembly into a wellbore that provides a water production zone and first and second oil production zones, the water production zone interposing the first and second oil production zones;
deploying the straddle packer assembly and thereby isolating the water production zone from the first and second oil production zones;
conveying an injection fluid to the straddle packer assembly, the injection fluid comprising a first formulated chemical comprising water, N,N′-methylenebisacrylamide (Bis), N,N′-(1,2-dihydroxyethylene) bisacrylamide (DHEBA), and acrylamide, and a second formulated chemical, comprising water, tetramethylethylenediamine (TEMED), and ammonium persulfate;
injecting the first formulated chemical into the water production zone;
injecting the second formulated chemical into the water production zone after the first formulated chemical;
reacting the second formulated chemical with the first formulated chemical and thereby creating a non-porous material; and
preventing an influx of water from the water production zone into the wellbore with the non-porous material.
