H₂S Scavenger
H₂S Neutralization,
Science-Backed, Field-Proven

In a H₂S-containing solution, there exists several species, H₂S, hydrogen bisulfide, and elemental sulfide. For an acid fracturing process, the pH is below 7, the majority of the sulfide will be in the form of H₂S. Therefore an acid fracturing fluid formulation design needs to consider the selection of an appropriate H₂S scavenger. In addition to its pre-existence in the reservoir, H₂S can also come from the acidizing process. Iron sulfide deposit can form in the tubular or near wellbore or being a part of the mineral composition in the rock matrix. H₂S is a reaction product of acid dissolving iron sulfide.

DOSAS, DoScav™ H₂S scavengers effectively protect oil, brine, and gas systems from H₂S corrosion, reducing maintenance costs and boosting efficiency.


H₂S Neutralization Chemicals

To achieve effective scale control, industry professionals employ a range of advanced formulas and cutting-edge technologies. From the selection of appropriate scale solution chemicals to the implementation of state-of-the-art monitoring systems, every aspect is carefully considered.

Evaluation of H₂S Scavengers
for Stimulation Treatment

DOSAS provides test methodologies designed to evaluate the scavenging performance of these products and their impact on other areas of stimulation, such as scale formation and control, and compatibility with other fracturing and acidizing additives.
