Cost effective H2S management in oil and gas production

Historically low prices on crude oil and gas puts pressure on the upstream part of the industry for cost reduction. Big data opens a world of possibilities for operators of offshore platforms, land based oil wells and refineries, enabling them to respond to the still increasing demands for cost effective and safe production.

H2S Petro is a robust, industrial-grade hydrogen sulfide (H2S) sensor for liquid and gas phase measurement, and it is as such a key enabling factor to engage cost effective management of H2S in the oil and gas industry.

High concentration of H2S in sour gas and crude oil poses a major problem on oil and gas platforms and wells, because it needs to be reduced to low target levels before exportation. Operators use vast amounts of scavenger chemicals and solvents to do so, and moreover the still present amount of H2S creates massive cost of corrosion as well as safety hazards throughout the production facility.

The concentration of H2S in oil and gas is a key input to true intelligent dosing of scavenger chemicals and solvents, and to run big data maintenance programs of pipe exchange etc. Therefore, operators engage vast amounts of labor-intensive sampling as well as installation of different types of gas phase sensors to monitor the concentration of H2S in the gas before exporting. Unfortunately, most gas sensors available were developed for work place safety (personal safety equipment), and when they are applied upstream for the control of scavenger chemical dosing, they fail, mainly due to the harsh conditions of high temperature, high H2S concentration and high pressure.

The unique electrochemical technology and heavy duty design of H2S Petro enables in-line measurement in petrochemical liquids and gases under harsh conditions up to 15,000 ppm.
