Product Information 

OS FORM PLUG is the basis of the OS FORM PLUG SYSTEM as a treatment for extreme lost circulation.


It is a blend of milled borate mineral and selected polymers designed to be mixed in water or approved brines.



It can be mixed and the resultant fluid kept as a premix and held for extended periods.   

This may require treatment if used in hot climates, i.e. the addition of biocide and/or oxygen scavenger.


Particle size does not exceed 100microns and can therefore be safely pumped through down hole motors, LWD & MWD tools etc.



OS FORM PLUG is packaged in 50 lb sacks.
