Abstract
Provided are systems and methods for freeing differentially stuck pipe via the in-situ release of fluids from fluid-releasing tanks coupled to a centralizer or stabilizer of a pipe. Fluid-releasing tanks may be coupled to a centralizer or stabilizer of a pipe and located around the circumference of the pipe. Nozzles may be connected to the fluid-releasing tanks to enable the in-situ release of fluid from the fluid-releasing tanks. Various mechanisms may be used to open the nozzles and release the fluid from the fluid-releasing tanks.
