toto,

It can be a little unnerving working around H2S. I've been on wells drilling sour gas sections and you don't sleep well. An FSOP flaring 20 million cf of NG a day is a scary place too. But H2S can be a curse or a blessing. There have been times when the S market is high and operators make a nice bonus on the recovery process. I haven't watched the S market in some time. But $900/ton sounds likes a strong market. If Shell et al believe the market is stable they might push development on those sour fields where it was only the H2S content holding them back.

As a biologist that works with H2S, I have to wonder if there's an economical way to use microbes to remove it from the gas. There are many different sulfide oxidation pathways that yield different end products (not just elemental S but polysulfides, thiosulfate, polythionates, etc.) which are less toxic and potentially easier to remove.

Maybe Ashen but I suspect scalabilty and the time factor might be the difficulty with such an approach. A few thousand cf per day perhaps but 25 million cf per day is a lot to deal with. The NG has to be processed right then and quickly. No way to store any appreciable amount of NG in a gaseous state in an offshore environment.

Rockman, Thxs for your reply.
