Abstract
A corrosion inhibitor package containing an acetylenic amine or acetylenic alcohol enables a sulfur-free method for protecting metal tubulars and equipment. The package has particular applicability in the protection of carbon steel tubulars in high density brines at elevated temperatures. The corrosion inhibitor package may contain a transition metal oxide as a corrosion inhibitor intensifier.
