... of simple, easily implemented, insulated coupling designs, and the confirmation that wellbore heat loss in refluxing annuli scales with annulus pressure in a predictable manner, suggests that much of this loss is preventable. annulus water enhanced recovery sensor sta heat flux transfer rate...

..., the following analysis is based on integral balances for the total thermal energy and the latent heat and employs the assumptions of constant steam zone temperature and constant average volumetric heat capacities. Combined with expressions for the heat fluxes in the limiting cases discussed in Reference 2...
