Sacrifice fluid (water) in PMCD HPHT

24 November 2009 Gents
want to get some opnion
Reservoir data pore press = 14.5 ppg (9500 ft sand stone 380 F)
if we are on PMCD mode (pressurized mud cap drilling --> loss and kick)--> 8-1/2" hole --> 300 ft

Annulus using 14 ppg (OBM) --> Back press 250 psi (flowting mud cap
Sacrifice fluid using water (8.33 ppg)--> will effect high pump press

is it possible using water for sacrifice fluid for injecting through string? what the effect of water on hi temp above boiling point and higher under balance from pore pressure?

what the best fluid type for annulus (mud cap) and string (injecting)?
and what the best weight annulus fluid and string fluid?
