Handling of Hydrogen Sulfide and Mercaptans in Oilfield Production - A Matter of Economics

May 16, 2019

For the exploitation of oil and gas fields, oil and gas producers face many challenges related to exploration, production methods and subsequent handling of the produced fluids

By Carlos Gonzalez


Among these challenges, the presence of hydrogen sulfide and heavier organic sulfur compounds constitutes a significant technical, environmental, economic, and safety challenges in all segments of petroleum industry, from upstream, through midstream to downstream. In special, gas associated to reservoirs that have been in production for years and are subject to enhanced oil recovery methods may have a high CO2, H2S, mercaptans and heavier sulfur compounds that may prevent further economic development of these oilfields.

This paper was presented at the 2019 GPA Midstream conference by Stantec's Carlos Gonzalez, vice president, sector leader, oil & gas. It presents experiences developed with different producers to handle the H2S and organic sulfur compounds to allow the production of mature oilfields.
