Product Description
PIPE NW is a water-dispersible, low-toxicity spotting fluid designed to free differentially stuck pipe by penetrating between the wall cake and drill string. PIPE NW spotting fluid also offers strong metal wetting characteristics and will act as a lubricant after added into the active system
Application
PIPE NW additive is a single-package, low-toxicity spotting fluid. It can be used for environment sensitive offshore and onshore wells where a low-toxicity, non-oil-base spotting fluid is specified.
Success in freeing differentially stuck pipe is greatest when the spotting fluid is applied as soon as possible after the pipe becomes stuck. A fluid that can be mixed and spotted quickly often frees the drill string before fishing operations are required. Because PIPE NW additive is a single package, liquid blend made for fast mixing, it is ideal for spotting situations.
PIPE NW additive contains no hydrocarbons, is compatible with most mud system and can be used either weighted or unweighted in wells with differentially stuck pipe. If a density greater than 9 lb/gal (1.08 s.g.) is required, the PIPE NW spot should be weighted with weighting materials. If a density less than 9 lb/gal (1.08 s.g) is required, PIPE NW additive should be used “neat”, without dilution. Water should not be added to PIPE NW slurry for any reason. This causes an undesirable increase in viscosity.
