Claim 8:
9. A wellbore system, comprising:
a wellbore extending from a well surface location and providing a water production zone and first and second oil production zones, the water production zone interposing the first and second oil production zones; and
a straddle packer assembly installed in the wellbore to isolate the water production zone from the first and second oil production zones,
wherein an injection fluid is injected into the water production zone from the straddle packer assembly to create a non-porous material that prevents an influx of water from the water production zone into the wellbore,
wherein the injection fluid comprises 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, and
wherein the second formulated chemical is injected into the water production zone after injection of the first formulated chemical to react with the first formulated chemical and thereby create the non-porous material.
