There is provided aqueous fluids comprising a mixture of at least two polysaccharides, water, and glass microspheres having pacified surfaces. There is also provided a method for making a fluid the method comprising (a) selecting a plurality of glass microspheres having alkaline surfaces; (b) coating the surfaces of the plurality of glass microspheres with an acid; and (c) combining the coated glass microspheres with (i) a mixture comprising at least two cross-linkable polysaccharides, and (ii) water. The fluids are useful, for example, as a drilling fluid.

Fluid composition comprising glass microspheres and method of making and using the same

A plurality of solid particles including a thermoplastic composition having a softening temperature in a range from 50&#xb0; C. to 180&#xb0; C. and a blocked isocyanate resin; optionally at least some of the particles in the plurality of solid particles comprise both the thermoplastic composition and the blocked isocyanate resin. A composition comprising the plurality of particles dispersed in a fluid is also disclosed. A method of modifying a wellbore within a geological formation is also disclosed. The method includes introducing the fluid composition into the wellbore. A method of making a plurality of particles, for example, to use in the fluid composition, is also disclosed.
