A wood-based loss circulation material is formed with a density matched to the density of the drilling fluid to which the loss circulation material will be added. The material is formed from sawdust or fiber pressed under high pressure into high-density pellets. The resulting pellets are brittle, and may be crumbled and screened into particles of an appropriate size for a particular drilling fluid application. Different particle sizes may be employed to prevent seepage or fill voids during the well drilling process. The particles do not disassociate into their constituent materials when in the drilling fluid, and thus maintain their density during use.
