I believe that underbalanced gear is being brought in right now for usage in both #3 and #4.

The uncontrolled flow rate of "12,000 bpd" is a myth. Usually companies test oil wells at 2" and then 1/2" chokes. A controlled flow test would be much less than the historic blowout flow rate of the original well.

"During the day on November 24, 2005 a series of short five minute flow tests was conducted over a
two hour period. Based on these short-duration flow tests, the well flowed at extrapolated calculated
rates ranging from 750 bbl/d to 2,400 bbl/d on one-half inch to two inch chokes, respectively. A
stabilized flow rate has not yet been established. There is a risk that stabilized flow rates will be less
than the flow test rates and in the opinion of management it is more likely than not that the stabilized
flow rate, when established, will be closer to the lower end of the extrapolated calculated range when
the well is placed onstream. Well head pressures were consistent with earlier results and the impact of
altering choke sizes during the testing program. "
