n: a liquid. usually salt water or oil. but sometimes mud. used in a well when a packer is between the tubing and the casing. Packer fluid must be heavy enough to shut off the pressure of the formation being produced. must not stiffen or settle out of suspension over long periods of time. and must be non-corrosive.

n: any fluid placed in the annulus between the tubing and casing above a packer. Along with other functions, the hydrostatic pressure of the packer fluid is utilised to reduced the pressure differentials between the formation and inside of the casing and acr

the fluid left in the annulus behind the packer. It may help offset pressure in the tubing or help reduce thermal losses.
