Spotting Fluid is also known as Pipe Free or Stuck Pipe Agent which is liquid containing a long-chain fatty acid compound blend of surface active agent, surfactant, and wall cake cracking material formulated to serve as water in oil emulsifier and oil wetting agents.
It is used to release differential stuck pipes easily and effectively. It is Thermally Stable.
It penetrates and dehydrates the wall cake. It improves lubricity, reducing contact between the pipe and wall. It is compatible with fresh and saltwater Drilling Fluids and can be added to active mud systems without adversely affecting other properties.
