Application

The unique properties of PIPE W (mixed with mineral oil, crude oil or oil-base drilling fluid) make it a superior product for preparing a spotting fluid or soak solution for freeing pipe that is differentially stuck. It forms a spotting fluid with a high-fluid-loss, solids free filtrate that penetrates and “cracks” the water-base filter cake, allowing the lubricating solution to equalize differential pressure rapidly and reduce the forces required to free differentially stuck pipe.

PIPE W is a convenient and easy to use liquid product that is effective in very small concentration and has an excellent success record. The recommended concentration is 1 gal (3.8 l) PIPE W for each bbl (0.16 m3) of spotting fluid to be prepared. Laboratory data indicates that PIPE W does not become more effective at concentration higher than this 1-to-1 ratio. This easy-to-use product, with its convenient 1-gallon-to-1-barrel ratio, is preferred over sacked spotting fluid product which require more time to mix, with more detailed formulations and mixing instructions.
