Magma Fiber™ – Inert Loss Circulation Material

For bridging & plugging off voids, fractures & all types of permeable formations

Magma FiberMagma Fiber™ is a specially formulated, extrusion spun mineral fiber.   Magma Fiber™ is compatible with all oil and water based muds and emulsion.   The interlocking nature of these strong fibers provides a framework for forming a low permeable mud cake with a resultant reduction in drilling fluid loss and hole caving.   Magma Fiber™ is inert to drilling fluids and is particularly adaptable to rework operations.
