Microfiber Bridging Agents

Our microfiber agents are specially manufactured, acid-soluble mineral fibers that interlock to form a strong, dense filter cake that bridges and plugs voids and fractures. Because they are thermally stable in excess of 500°F and compatible with fresh water, completion brines and diesel oil-based muds, TETRA Magmafiber agents are also used to treat lost circulation in wells with high bottom-hole temperatures.

TETRA Magmafiber Fine Microfiber Agent

Composed of fine acid soluble microfibers, TETRA Magmafiber Fine agent seals micro-fractures, as well as permeable and under-pressured sand formations.

TETRA Magmafiber Regular Microfiber Agent

Composed of medium-sized acid soluble microfibers, TETRA Magmafiber Regular agent seals micro-fractures, as well as permeable and under-pressured sand formations.
