OPERATIONAL FEATURES/BENEFITS OF FAC TOOLOPERATIONAL FEATURES/BENEFITS OF FAC TOOL

• Ability to check that float equipment is functioning correctly immediately after making up into casing string.

• Time savings realized by filling each casing joint as it is run vs. shutting g y g g j gdown to fill casing with mud hose.

• Reduces the risk of stuck casing by eliminating down-time to fill casing• Ability to immediately circulate casing by engaging element creates a saferAbility to immediately circulate casing by engaging element creates a safer

working environment by eliminating the need to install a pump-in swage.Also allows for immediate well control by circulating heavier fluids asneeded.

• For applications where self-filling float equipment is used, it allows forcontrol of mud that might otherwise spill over the open casing necessitatingcleanup.p
