Note:

Enviro-Syn BSD-40 is a ready-to-use sulfate scale dissolver used to remove barium, strontium, and calcium sulfate scale—including NORM—from downhole, surface, and industrial systems.

Executive Summary

Enviro-Syn® BSD-40™ is a specialized liquid solution used to remove tough sulfate scale, such as barium, strontium, and calcium sulfate, from oil and gas systems. These types of scale can clog pipes, damage equipment, reduce flow, and even contain NORM (naturally occurring radioactive material), all of which can disrupt operations and increase costs.

BSD-40 is ready to use straight from the container—no mixing or extra chemicals required. It includes a built-in surfactant that helps strip away oil coatings so the product can reach and dissolve the scale more effectively. This makes it suitable for both downhole and surface applications, including wells, pipelines, tanks, and processing equipment.

BSD-40 works at lower temperatures, dissolves more scale faster, especially barium sulfate, and is safer to handle.

Detailed Description

Enviro-Syn® BSD-40™ is a specialized sulfate scale dissolver formulated for use in a variety of oil and gas, geothermal, and industrial applications. It effectively removes barium, strontium, and calcium sulfate scales including naturally occurring radioactive material (NORM) that commonly cause flow restrictions, equipment fouling, and reduced heat transfer efficiency. The product is ready to use with no additional additives required, simplifying application and improving operational efficiency.

Scale buildup in pipes and equipment can significantly reduce flow rates and damage valuable assets which can lead to costly downtime and repairs. Enviro-Syn BSD-40 works by chemically dissolving these sulfate scales, restoring proper flow and protecting equipment from further damage. Its built in surfactants help remove oily coatings that often prevent scale dissolvers from working effectively, ensuring thorough and efficient cleaning.

This product can be used both downhole in wells and tubing and on surface equipment like pipelines, heat exchangers, and boilers. It performs well across a wide temperature range and dissolves even the toughest scales at lower temperatures making it suitable for many operational conditions.

Safety is an important consideration when selecting a scale dissolver. Enviro-Syn BSD-40 is non corrosive to skin, has a lower pH than many alternatives, and meets regulatory standards for safe transportation and handling. The BSD-40N version is approved for offshore use in the North Sea, meeting strict environmental requirements.

Corrosion testing shows that BSD-40 is compatible with common metals used in oilfield equipment, minimizing the risk of damage during treatment. For storage, it should be kept in sealed containers and used with specific fittings such as HDPE, brass, or stainless steel to maintain product integrity.

Enviro-Syn BSD-40 offers a safe, effective, and easy to use solution for managing sulfate scale.
