Abstract
A thermal insulating composition containing an organic solvent of low thermal conductivity and a gelling agent hydratable in the solvent is useful for controlling heat transfer from a production tubing or transfer pipe in a wellbore to a surrounding annuli and/or the environment. Further, the composition is capable of reducing convection flow velocity within the annulus surrounding production tubing or a transfer pipe.
