n: term applied to many heat resistant and chemically inert fibrous minerals, some forms of which are used in certain drilling fluids. It finds only limited use because prolonged exposure can cause respiratory illness.

n: Usually refers to the fibre of different length made by asbestos. Usually used as block agent in porous
thief formation.

n: The fissile or grained fibre material added into drilling fluid or cement slurry. Used to bridge leakage formation.

fluid loss control material that bridges against the leakoff site.

n: a nonfermenting cellulose product used in drilling fluids to combat contamination from anhydrite (gypsum) and to lower the water loss of the mud.

n: A production manufactured by acetic acid chloride after plant fibre is alkalized. Usually used as filtrate reducer and adhesion promoter.

n: a stranded rope made from Manila hemp or other fibre

n: the substance made by confusing fibre into dry cement or cement slurry, used to seal off and handle the leaking well during drilling and workover


cement with small hair like fibers that build strength or help control fluid loss.

n: Any tough stringy material used to prevent loss of circulation or to restore circulation. In field use, fibre generally refers to the larger fibres of plant origin.

n: cord or rope of vegetable or synthetic fibre used as the axial member of a rope.

n: Any tough stringy material used to prevent loss of circulation or to restore circulation. In field use, fibre generally refers to the larger fibres of plant origin.

n: a stressed-steel corrugated tube that is lowered into existing casing in a well to repair a hole or leak in the casing. The patch is cemented to the casing with glass fibre and epoxy resin.

n: A downhole assembly or tool system used in the remedial repair of casing damage, corrosion or leaks. Casing patches are most frequently used as short- to medium-term repairs that enable production to be resumed until a major workover operation is schedule

n: (LCM) a substance added to cement slurries or drilling mud to prevent the loss of cement or mud to the formation. See bridging materials.

n: materials added to the mud to control or prevent lost circulation. These material are added in varying amounts and are classified as fibre, flake, or granular.
