Abstract:
1. A method of completing a well comprising: including nano-particles in a completion fluid, wherein the nano-particles are selected from the group consisting of nano-silica, nano-alumina, nano-zinc oxide, nano-boron, nano-iron oxide, nano-barium sulphate, nano-manganese tetraoxide, nano-magnesium oxide, nano-calcium carbonate, nano-graphite, nano-barium oxide, nano-cerium oxide, nano-lanthium oxide, nano-titanium dioxide, nano-clay, nano-aluminosilicate, and any combination thereof; wherein the nano-particles are present in the completion fluid in an amount in a range of from about 10% to about 70% by weight of the completion fluid; and wherein the completion fluid has a density in a range of about 7.5 pounds per gallon to about 22 pounds per gallon; introducing the completion fluid into a well bore; and using the completion fluid in completing the well, wherein micron-sized or larger particles are not present in the completion fluid when completing the well such that the completion fluid does not plug production screens or other downhole equipment.
