When casings are being removed from wells for various reasons, the fluid stuck to the inner walls creates a mess on drill floor, pipe deck and during transportation back to land. The accumulated volume of this residual fluid is surprisingly large and generates several cost elements such as increase mud consumption, increased slop treatment and increased cost when casings are being destructed. Additionally, there are significant HSE benefits such as less well fluid spill on drill floor and less work in red zone when the fluid is left in the well.
CleanPipe is designed to wipe the inside of the casing. When ready to pull the casing out of hole, simply slug the casing and drop the Cleanpipe tool inside.
