LEAK DETECTION IN CIRCULATED FLUID SYSTEMS FOR HEATING SUBSURFACE FORMATIONS |
摘要 |
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.
