1. A system for use of desulphated injection water from offshore platforms in inhibition squeezes, comprising:
a producing well;
a pig launcher or receiver upstream from the producing well;
a first fitting upstream from the pig launcher or receiver;
a T fitting upstream from the first fitting, the T fitting configured to receive inhibitor fluid and desulphated injection water;
a first check valve and a second check valve respectively upstream from the T fitting;
a hose upstream from the first check valve, the hose configured to provide the inhibitor fluid to the T fitting via the first check valve;
a second fitting upstream from the second check valve;
a choke valve upstream from the second fitting;
a water flow rate meter upstream from the choke valve;
a desulphated water injection header upstream from the water flow rate meter, the desulphated water injection header configured to provide the desulphated injection water to the T fitting via the water flow rate meter, the choke valve, the second fitting, and the second check valve; and
lines respectively connecting the T fitting to the first fitting, the first check valve to the T fitting, the hose to the first check valve, the second check valve to the T fitting, and the second fitting to the second check valve.
