In 2020, an oil field in western China detected that the H2S content in two oil wells seriously exceeded the standard. One of the wells had a H2S content of 576ppm and required the use of a certain amount of sulfur removal agent to reduce the H2S content to less than 10ppm. The other well had a H2S content of 385ppm and required it to be reduced to 9ppm. Within this field, a moderate amount of SCAVE SUL is used in this oil field After 08, the H2S content of the first well was reduced from 576ppm to 6ppm, and the H2S content of the second well was reduced from 385ppm to 5ppm. H2S Scavenger successfully completed the sulfur removal work of high H2S oil wells
