The properties of lemongrass fibers are being studied as a potential help in preventing fluid circulation problems while drilling for oil and gas. In the oil and gas industry, drilling mud is used to (1) to suspend cuttings to prevent it sagging at the drill bit during shutdown, (2) to transport it to the surface, (3) to cool and lubricate the drill bit, (4) to provide enough hydrostatics pressure to prevent fluids from formation enter to the well bore and (5) to form a thin filter cake to seal the damage formation.
