  • Patent number: 11879089
    Abstract: A treatment fluid can include a base fluid and a lost-circulation package. The lost-circulation package can include plurality of particles of a first, second, and third lost-circulation material. The plurality of particles can be cellulose, sized calcium carbonate, and fibers. The particle size distribution of the plurality of particles can be selected such that the particles enter permeable areas of a subterranean formation to help prevent loss of the base fluid into the formation and allow most of the particles to pass through the screen of a shale shaker. The plurality of particles can have a particle size distribution of a d10 value in the range of 30 to 55 microns, a d50 value in the range of 60 to 100 microns, and a d90 value in the range of 130 to 190 microns. The treatment fluid can be used in an oil and gas operation.
