Sour Gas - H2S
Exposure Testing
In some parts of the world (e.g., Caspian), the hydrogen sulphide
content of reservoir fluid is very high. H2S is a reactive
gas, as well as being extremely toxic. H2S can be re-injected,
rather than converted to sulphur, as a means of safe disposal and
of maintaining
reservoir pressure. Certain premium oilfield polymers perform well
in sour environments at elevated temperatures, but others do not.
MERL sour gas test experience covers seals, spoolables (pipe, umbilical,
hose) and insulation. |
