1. A system for freeing differentially stuck pipe in a wellbore, comprising:
- a differentially stuck pipe in a wellbore;
a plurality of components disposed along the length of the pipe, wherein each of the plurality of components is a centralizer or a stabilizer;
a fluid-releasing tank coupled to one of the plurality of components, the fluid-releasing tank containing a fluid; and
a nozzle connected to the tank and configured to release the fluid into the wellbore such that the fluid interacts with the material contacting the pipe.

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.

12. A method of freeing differentially stuck pipe in a wellbore, comprising:
-
initiating the release of a fluid from a fluid-releasing tank coupled to one of a plurality of components disposed along the length of the differentially stuck pipe, wherein each of the plurality of components is a centralizer or a stabilizer, such that the fluid is released through a nozzle into the wellbore and interacts with a material contacting the pipe; and freeing the differentially stuck pipe after the fluid interacts with the material contacting the pipe. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
