A portable system is described for the continuous injection of corrosion-inhibiting chemical into a production well, comprising: a portable skid; a corrosion-inhibiting chemical tank, and a water tank, mounted on the skid; pump means for pumping an desired amounts and proportions of chemical and water from the tanks for injection into a production well. The pump means is mounted on the skid. A conduit means operatively interconnects is the pumps and tanks for delivery of corrosion-inhibiting chemical to a production well, the conduit means including an end conduit for operative interconnection to a production well. A control means is mounted on the skid for controlling the operation of the pump means to provide desired amounts and proportions of a mix of corrosion-inhibiting chemical and water to the end conduit. A method is described for delivering a mix of corrosion-inhibiting chemical and water to a production well utilizing a portable skid having a chemical tank and water tank mounted thereon, comprising: transporting the skid to a single production well site; operatively interconnecting the chemical and water tanks to an injection tube string, or an annulus associated with a side mandrel, of the production well; and controlling delivery of a mix of corrosion-inhibiting chemical and water from the tanks to the production well so that any desired amounts and proportions of a mix of chemical and water are continuously injected into the well to provide corrosion-inhibiting of a production tube string of the well without interruption of production through the production tube string.
