New type water in water PHPA/polyacrylamide emulsion

PHPA A1 

Most Advanced Technology……….Highly Environmentally Friendly Chemicals 

Product Description : water in water Anionic polyacrylamide emulsion

PHPA A1 is a low viscosity, liquid emulsion of a high molecular weight Partially Hydrolyzed Polyacrylamide (PHPA).

Typical Application

PHPA A1 is applicable for use in water based drilling fluids, as a water shutoff agent, shale stabilizer, encapsulating agent and flocculant. This product is functional in fresh water, seawater, KCI brine, and salt (NaCI) water based drilling fluids.

Product Advantages

- A versative multi-functional additive for most water based drilling fluids.

- Easily handled and mixed, disperses rapidly into the drilling fluid.

- Pourable in cold weather climates at a temperatures as low as -25°F.

- Produces shear thinning fluid properties, and excellent hole cleaning characteristics.

Recommended Treatment

For shale stability and encapsulation, a concentration of 1.0 to 4.0 qt/bbl (0.6 - 2.4 l/m3) of  PHPA A1 is normally required. PHPA A1 may be added directly to the surface of a well agitated mixing or suction pit. Additions through the chemical hopper may cause foaming or aeration of the mud.

When using PHPA A1 as a flocculant, treatment requirements should be pilot tested, but will generally be less than 0.3 qt/bbl. As a flocculant, the product should be added as a water solution, into the flowline, upstream end of the reserve or settling pit, or to the centrifuge diluent water.

Handling

Employees should utilize normal precautions when handling chemical products. The use of a face shield or chemical goggles, chemical gloves and apron are recommended when handling this product. In case of eye contact, flush with clean fresh water for 15 minutes and seek medical advice. In case of skin contact, remove contaminated clothing and launder before reuse, wash the effected area with soap & water. Review the Material Safety Data Sheet (MSDS) for this product prior to use.

Storage

Store in closed containers, at ambient temperatures, in a ventilated area, protected from precipitation. Long term outside storage should be avoided to prevent deterioration of package and labeling.

Packaging

PHPA A1 is supplied in 25kg pails. 1000kg IBC ,or 250kg plastic drum..
