ABSTRACT:
The invention provides well working compositions containing a particulate additive to decrease the seepage loss of the fluid to fluid permeable formations contacted by the compositions. The additive comprises: (1) a cellulosic material selected from the group consisting of oat hulls, citrus pulp, beet pulp, paper, bagasse, peat, corn cobs, kenaf, rice hulls, rice bran, straw, cottonseed hulls, soybean hulls, and mixtures thereof (2) a particulate mixture of a first cellulosic material selected from the group consisting of oat hulls, cotton burrs, and mixtures thereof, and a second cellulosic material selected from the group consisting of beet pulp, paper, bagasse, wood, peat, kenaf, rice hulls, rice bran, cottonseed hulls, soybean hulls, straw, peanut shells, nut shells, cotton, and mixtures thereof; or (3) a particulate mixture of an oleaginous liquid and a cellulosic material selected from the group consisting of oat hulls, cotton burrs, citrus pulp, beet pulp, paper, bagasse, wood, corn cobs, kenaf, peat, rice hulls, rice bran, cottonseed hulls, soybean hulls, nut shells, straw, and mixtures thereof; provided that the cellulosic materials have a certain particle size distribution as set forth in the specification.
