Abstract:
1. A drilling, drill-in and completion fluid additive for use in a fluid composition comprising: a nanoparticle, the nanoparticle having an average particle size in a range of about 1 nm to about 100 nm and being operative to increase performance of the fluid due to the nanoparticle having high surface area to volume ratio; and a shield agent, the shield agent being operative to at least partially shield the nanoparticle so that the nanoparticle and the shield agent are adequately dispersed in the fluid in the absence of an external dispersing agent for use in drilling and completion applications, and the shield agent being present in an amount effective to viscosify the fluid and aid in dispersion of the nanoparticle in the fluid, wherein the shield agent comprises xylose and arabinose.
