clusters. A few of the cuttings with grain diameter greater than 2.00 mm or less
than 0.90 mm are carried by bubbles. However, most of the cuttings are depos-
ited at the bottom of flasks. Bubbles also adhere on the surface.

6.2.3 Evaluation of FGC-1 Cutting Carrying Effect
in the Simulator
A set of devices was independently designed to simulate and evaluate the
effect of FGC-1 cutting carrying agent in greatly displaced wellbores, at
