Rapid response tailgate testing prevents a multi-million-dollar capital expenditure for Senior Producer to safely manage Iron Sulfide

A senior oil and gas producer operating in the Grande Prairie region of Alberta was preparing for an impending
change in the production scenario within their Valhalla field, which historically produces, gathers, and processes
production from a mature (sour) Montney formation. The challenge was to identify strategies for managing iron
sulfide generation when new, (sweet) production from the Charlie Lake formation was to be introduced into the
existing sour gathering system and central treating facility.
