The Kuparuk zone test fluids are the foreign fluids referred to in the e-mail below. That pool was tested in Jan 2006 though Northstar well NS08 and was reported on the 10 -405 as pool 590500. What were the foreign fluids? There was no reported oil production this month or gas production from Kuparuk gas pool? Steve Fiedler, Anne M wrote: Steve, I got some additional information from the field (below). Let me know if you /Jim need more. Anne 564 -5826 Because the fluids produced from the Kuparuk zone were foreign to our process facility, we didn't know ahead of time how to prepare the plant to receive them. Because of this, the fluids created a process upset which led to an unplanned shutdown of the entire facility, with associated flaring.
