Abstract
The present invention provides methods of protecting ferrous metal well tubular goods and the like disposed in a well bore penetrating a subterranean formation from corrosion. The method basically includes the steps of introducing a liquid or solution of a tackifying compound having ferrous metal corrosion inhibition properties into the well bore whereby the tackifying compound is coated onto the tubular goods thereby providing extended corrosion protection to the tubular goods. Thereafter, formation fluids are produced from the subterranean formation.
Claims9
A method of protecting ferrous metal well tubular goods disposed in a well bore penetrating a subterranean formation from corrosion comprising the steps of:
- (a) preparing a carrying fluid having suspended therein, a particulate gravel impregnated or coated or both with a liquid or solution of a tackifying compound having ferrous metal corrosion inhibition properties;
- (b) introducing said carrying fluid and said particulate gravel impregnated or coated or both with said tackifying compound into the annulus between the walls of said well bore and a screen disposed in said well bore whereby a permeable pack of said particulate is formed in said subterranean formation;
- and
- (c) producing fluids from said formation by way of said permeable pack of particulate whereby portions of said tackifying compound are released or displaced from said particulate which coat said ferrous metal tubular goods whereby they are protected from corrosion.
