A method of plugging a hydrocarbon well includes deploying a downhole tool to remove at least a portion of a casing at a section of well to be plugged. Deploying a blocking device downhole to block a bottom of the section of well to be plugged. Deploying a plugging material downhole onto the blocking device to fill an area to be plugged. Deploying an exothermic fluid downhole, wherein activation of the exothermic material liquefies the plugging material. Allowing the plugging material and the exothermic fluid to solidify form a cast-in-place plug that fills the section of well to be plugged.

A process is directed at plugging a wellbore, wherein the wellbore has a portion extending at least partially through a caprock composed of salt rock. The process includes applying a barrier in the wellbore at or above the caprock. Thereafter, the process includes a step of promoting creep such that the salt rock in the caprock creeps into the wellbore to create a salt-rock plug in the wellbore, and hence, closes off the portion of the wellbore above the salt-rock plug from fluid flow communication with the portion of the wellbore below the salt-rock plug.
