" Well M-2 has a very long hole section which is estimated to have lost about 17,000 bbls of mud fitrate (by the end of this week)"

Can you please take me through the calculations used to arrive at this figure?

"a) Assume that 100 bbl/metre is distributed evenly in view of the fact that the Pebbly Arkose has already received fluid loss pills (LCM),

At an average ROP of 10m/hr that would amount to a loss rate of 1000bbls/hr. No mud system could keep up with losses of that magnitude....you simply can't drill a well with losses that high without seriously compromising the safety of the well.

I'm sorry but your calculations re mud losses don't make sense.
