ABSTRACT:
Corrosion inhibiting of well production tubing, such as for an oil or gas well, is provided in a simple and effective manner without interrupting well production. A portable skid has a chemical tank, water tank, pumps, conduits, and controls mounted on it, and is transported to the production well site. A mix of corrosion-inhibiting chemical and water is supplied from the tanks to an end conduit, and the end conduit is connected to an injection string, or an annulus associated with a side mandrel, of the production well. A computer control is provided for controlling the pumps, and other components, so that any desired amounts and proportions of a mix of chemical and water is continuously injected into the well to inhibit corrosion of the well production tubing string without interruption of production.
