H2S/sour gas

This paper demonstrates a small, low-cost, low-power, highly sensitive nanomaterial-based gas sensor specifically targeted for the detection of hydrogen sulfide (H2S).

This paper describes the first application of the 10¾-in. CV in a deep-well sour environment.

A single-step cryogenic-distillation process that removes carbon dioxide (CO2), hydrogen sulfide (H2S), and other impurities from natural gas has been developed by ExxonMobil.

Kuwait Oil Company started free gas production from its Jurassic sour-gas field in May 2008 with the commissioning of Early Production Facility (EPF) 50.

Semoga and Kaji fields experienced reservoir souring and suffered a history of calcium-carbonate (CaCO3) -scale cases before a proper scale-inhibition program was implemented. Problems with a free water knockout discovered continued scale issues, leading to investigation of the reasons.

ExxonMobil is testing its Controlled Freeze Zone technology, a single-step cryogenic process that allows carbon dioxide (CO2) to freeze in a controlled method and then melts the CO2. After recovery of the methane, the CO2 can be sequestered or used for EOR.
