Mitigating corrosion of carbon steel tubing and surface scaling deposition in oilfield applications

摘要

Mitigating corrosion and surface scale formation in a sour gas well includes providing an oil-based liquid to a sour gas well having carbon steel tubing (112) with iron sulfide on a surface of the carbon steel tubing (112), contacting the carbon steel tubing with the oil-based liquid, and adsorbing a first portion of the oil-based liquid onto the iron sulfide, thereby yielding a hydrophobic coating on the carbon steel tubing.
