A method of treating a subsurface formation includes circulating at least one molten salt through at least one conduit of a conduit-in-conduit heater located in the formation to heat hydrocarbons in the formation to at least a mobilization temperature of the hydrocarbons. At least some of the hydrocarbons are produced from the formation. An electrical resistance of at least one of the conduits of the conduit-in-conduit heater is assessed to assess a presence of a leak in at least one of the conduits.

A method of treating a subsurface formation, comprising: circulating at least one molten salt through at least one conduit of a conduit-in-conduit heater located in the formation to heat hydrocarbons in the formation to at least a mobilization temperature of the hydrocarbons;producing at least so
1. A method of treating a subsurface formation, comprising: circulating at least one molten salt through at least one conduit of a conduit-in-conduit heater located in the formation to heat hydrocarbons in the formation to at least a mobilization temperature of the hydrocarbons;producing at least some of the hydrocarbons from the formation;circulating an inert gas with the at least one molten salt;assessing a presence of a leak in the at least one conduit by assessing a presence of the inert gas inside walls of the at least one conduit; andassessing a depth of the leak below a surface of the formation. 2. The method of claim 1, wherein the leak comprises a breach in at least one of the walls of the at least one conduit. 3. The method of claim 1, further comprising continuously assessing the presence of the inert gas to assess the presence of the leak. 4. The method of claim 1, further comprising intermittently assessing presence of the inert gas to assess the presence of the leak. 5. The method of claim 1, further comprising assessing the presence of the inert gas to assess the presence of two or more leaks in the at least one conduit. 6. The method of claim 1, further comprising assessing the presence of the inert gas with a gas detection system coupled to the at least one conduit, wherein the gas detection system detects the presence of the inert gas in the at least one conduit. 7. The method of claim 1, wherein the inert gas is selected from the group consisting of nitrogen, argon, helium, or mixtures thereof. 8. The method of claim 1, wherein the inert gas releases from the at least one molten salt at pressures present in the at least one conduit during circulation of the at least one molten salt. 9. The method of claim 1, wherein the at least one molten salt comprises a carbonate salt. 10. A method of treating a subsurface formation, comprising: circulating an inert gas with a molten salt to form a mixture;providing the molten salt and inert gas mixture to one or more conduit-in-conduit heaters;circulating the molten salt and inert gas mixture through at least one conduit of at least one conduit-in-conduit heater located in the formation to heat hydrocarbons in the formation to at least a mobilization temperature of the hydrocarbons;producing at least some of the hydrocarbons from the formation;assessing a presence of a leak in the at least one conduit by assessing a presence of the inert gas inside walls of the at least one conduit; andassessing a depth of the leak below a surface of the formation. 11. The method of claim 10, wherein the leak comprises a breach in at least one of the walls of the at least one conduit. 12. The method of claim 10, further comprising continuously assessing the presence of the inert gas to assess the presence of the leak. 13. The method of claim 10, further comprising intermittently assessing presence of the inert gas to assess the presence of the leak. 14. The method of claim 10, further comprising assessing the presence of the inert gas to assess the presence of two or more leaks in the at least one conduit. 15. The method of claim 10, further comprising assessing the presence of the inert gas with a gas detection system coupled to the at least one conduit, wherein the gas detection system detects the presence of the inert gas in the at least one conduit. 16. The method of claim 10, wherein the inert gas is selected from the group consisting of nitrogen, argon, helium, or mixtures thereof. 17. The method of claim 10, wherein the inert gas releases from the molten salt at pressures present in the at least one conduit during circulation of the molten salt. 18. The method of claim 10, wherein the molten salt comprises a carbonate salt.
