Loss zone below kick zone


Consider this interesting case: 

  • Using MPD.
  •  Very high mud weight in use.
  • Well control event. 
  • Current mud weight is very, very  close to FIT.
  • Low-pressure zone below, that you need to drill to top of it. 

Likely that  once  losses incurred,  the well should start to flow (will cross flow into the loss zone)


  1. Once shut-in, what are the shut-in pressures going to be?
  2. What is the best solution in this situation if happens?
