The corrosive effects of hydrogen sulfide result in significant additional operating costs for production including higher pipeline failure rates as well as souring of the produced oil and gas. In order to mitigate the effects of hydrogen sulfide and produce in spec oil and gas chemical scavengers are often applied typically topside and post-separation. Downhole injection has the benefit of providing the opportunity to remove H2S at the earliest point of the production system but more traditional chemistries can significantly impact scale deposition downhole or cause corrosion on production equipment. We report case histories of a new non-scaling chemical scavenger that exhibits excellent hydrogen sulfide scavenging performance for downhole applications. In addition we show how detailed knowledge of the system parameters and the kinetics and mechanism of H2S scavenging provide a means for predicative performance and optimization within individual systems.Key words: hydrogen sulfide chemical scavenger downhole injection kinetics non-triazine

Laboratory performance evaluations and field data of the non-triazine based high temperature stable H2S scavenger will be discussed. The new H2S scavenger acts as a corrosion inhibitor and is thermally stable up to 200°C. It does not promote scale as observed during dynamic scale loop evaluations.
