The BioDrill GreenScav technology combines metal salts with lignin-based chelating agents to provide completely soluble H2S scavengers for use in most brine and fresh water drilling fluid systems. The high solubility of GreenScav scavengers improves reaction rate and the metal’s availability, resulting in high H2S scavenging efficiency, as well as aiding dispersion of solids and providing some degree of protection against corrosion. Furthermore, rheological problems arising from the use of insoluble metal salt scavengers are avoided.
