Jim,
Thanks for response. I'll probably have a few more questions once I digest
all the info that you provided.
Regards, Darrell

Excuse me, thats 97.8% of the days that were greater than 516 psig.

Darrell, Attached is a history (last 365 days) of the suction pressures of
Station 20 arranged in descending order. In a nutshell, we looked at the
minimum pressure (492 psig), calculated the pressure drop (34# at 54.4
MMcf/d) on the proposed 6.6 miles of 12" to get 458 psig at the upstream side
of the regulator. Typically we would like to have a 50# differental across
the regulator, which would give us 408 psig downstream of regulation. I
believe you were needing 435 psig.



Looking at the it in reverse, 435 psig + 50 psig across reg = 485 psig,
calculate pressure drop (31 psig), we would need 516 psig at the suction of
Station 20. Note there are only 8 days during the last year where the
pressure was lower than 516 psig or 97.8% of the time.

Please call me if you would like to discuss further or would like to meet.
