A thermal insulating packer fluid contains an organic solvent of low thermal conductivity and a gelling agent which is hydratable in the solvent. The composition is capable of inhibiting unwanted heat loss from production tubing or uncontrolled heat transfer to outer annuli. The viscosity of the composition is sufficient to reduce the convection flow velocity within the annulus.
