Pipefree

Pipefree

PIPE-LAX additive is used in diesel oil or in oil-base muds to form a highly effective stuck-pipe spotting fluid. PIPE-LAX enables spotting fluids to penetrate and "crack" the water-base-mud filter cake with an extremely high-fluid-loss and solids-free filtrate. These features allow the PIPE-LAX and oil solution to pass through the waterbase- mud filter cake between the stuck pipe and wellbore wall to facilitate freeing differentially stuck pipe

Typical Physical Properties

• Physical appearance- Dark brown liquid
• Specific gravity- 0.90
• pH (1% solution)- 5.6-6.6
• Flash point- 140^OF (60^OC) (PMCC)
• Pour Point- <15^OF (<^OC)

Applications

The unique properties of PIPE-LAX (mixed with mineral oil, diesel 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, solidsfree 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-LAX is a convenient and easyto- use liquid product that is effective in very small concentrations and has an excellent success record. The recommended concentration is 1 gal (3.8 l) PIPE-LAX for each bbl (0.16 m3) of spotting fluid to be prepared. Laboratory data indicates that PIPE-LAX does not become more effective at concentrations 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 products which require more time to mix, with more detailed formulations and mixing instructions

Advantages

• May be used in diesel oil, mineral oil, crude oil and oil-base muds
• May be used in weighted oil-base fluids where well control considerations require weighted fluids
• Convenient liquid additive, quick and easy to mix at the rigsite
• Easy to remember 1-gallonto-1-barrel ratio
• Has an approximate 85% success ratio
• Results in less time lost due to stuck pipe
  

Limitations

• Although unweighted spotting fluids are more effective, the reduction in hydrostatic pressure with an unweighted spotting fluid may be intolerable due to well control or regulatory requirements. For these instances, a weighted spotting fluid of PIPE-LAX in oil-base mud should be used
• Environmental restrictions concerning the use of oils and oil-base fluids should be considered, since PIPE-LAX is used in conjunction with oil
  

Toxicity and Handling

Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described on the Transportation and Material Safety Data Sheet (MSDS). Because PIPE-LAX contains refined oil and is used in oil and oil-base fluids, this product and the spotting fluids formulated with this product should be used in accordance with applicable environmental regulations and considerations. WARNING! Combustible liquid and vapor. Contains diesel fuel oil, inhalation of which may cause cancer. Material is an irritant

Packaging and Storage

PIPE-LAX is available in 5-gal (18.9-l) cans or 55-gal (208.2-l) drums. Store in a location away from sources of heat or ignition
