NOTE:
It has often times been operator preference
to employ salts to meet density requirements
for the purposes of minimizing unwanted solids
while drilling reservoir sections or for the
additional inhibition benefits certain salts
provide.
Weighting
agents such as calcium carbonate and barite
have been used. We often recommend the use
of specifically sized calcium carbonate for
the purpose of minimizing initial pressure
transfer associated with exposing low pressure
formations to high annular pressures during
the drilling process. |
