Vanconol® ET-101 Oil and Gas Well
Corrosion Inhibitor
1. 🎯 Abstract
Vanconol® ET-101 is a high-efficiency, environmentally friendly corrosion inhibitor specifically designed for oil and gas well production. It can effectively address metal equipment corrosion caused by dissolved oxygen, H₂S, CO₂, chloride ions, and other corrosive media. By forming a dense protective film on the metal surface, it significantly reduces the corrosion rate, extends the service life of equipment, and ensures the safety of the production process.

3. 🛠️ Application Guide
3.1 Recommended Application Fields
Vanconol® ET-101 corrosion inhibitor is particularly suitable for corrosion protection of metal equipment such as sucker rods, oil pipes, and wellbores during oil and gas well production, effectively extending equipment service life and reducing safety risks.
3.2 Usage Methods and Recommended Dosage
Pre-operation Preparation: Check if the product packaging is intact and confirm that the product in the barrel is in a molten state (preheat and melt if solidified).
Dosage Calculation: Calculate the required weight of corrosion inhibitor based on the produced water volume. The recommended dosage is not less than 15ppm; under high-temperature (>65℃) working conditions, the recommended active ingredient content is not less than 75ppm. The specific dosage can be determined through laboratory tests according to the content of corrosive media in oilfield produced water.
Dilution and Dosing: Can be diluted with demineralized water as needed on-site. Add the calculated amount of corrosion inhibitor to a dedicated container and then uniformly dose it into the system.
4. ⚠️ Safety and Storage
Safe Operation: Wear protective gloves and goggles during use to avoid direct contact with skin and eyes. In case of accidental contact, rinse immediately with a large amount of clean water and seek medical assistance.
Storage Conditions: Store the product in a clean, cool, and dry warehouse, away from direct sunlight, high temperature, and fire sources. During transportation and storage, protect from sunlight, fire, moisture, and collision.
Packaging and Shelf Life: The product is packaged in plastic barrels with a net content of 220L per barrel; other packaging can be customized according to user requirements. The shelf life is one year at room temperature. Seal the remaining product after use to prevent volatilization.
