PHPA Partially Hydrolyzed Polyacrylamide Suppliers
PHPA (also partially hydrolyzed polyacrylamide or HPAM) is designed for easy mixing in drilling mud systems and to improve its dispersion to eliminate “fish eyes”, This occurs in field work when mixing either large quantities rapidly or mixing high polymer concentrations without good mixing equipment.In drilling fluids, PHPA is an anionic polyacrylamide and it can act as a viscosifier
PHPA | Partially Hydrolyzed Polyacrylamide
PHPA (Partially Hydrolyzed Polyacrylamide) Powder should be added in fresh water to get a highly viscous drilling fluid in Delhi. The marsh funnel viscosity for clay or shale formation should be ≥ 50 seconds per quart and ≥ 60 seconds per quart for sandstone or unconsolidated sand.

Decrease in viscosity of partially hydrolyzed
1. Introduction. Partially hydrolyzed polyacrylamide (HPAM) is a linear polymer with high molecular weight and plays an important role in enhanced oil recovery (EOR) by increasing the viscosity of flooding fluid (Wang et al., 2003, 2009a, 2009b).Usually, the viscosity of HPAM solution is determined by its chemical structure, molecular weight, degree of hydrolysis, concentration and further

Viscosity of partially hydrolyzed polyacrylamide under
Polymer flooding is the most successful chemical method to enhance oil recovery. This technique has achieved large-scale field application in China. Polymer flooding is also being tested in several heavy oil fields. For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery.
Effect of partially hydrolyzed polyacrylamide
When HPAM concentration increases from 0 to 500 mg/L, the viscosity value increases from 1.10 mPa s to 1.30, 1.34 and 1.38 mPa s for the case of MW of 6.5×10 5, 1.55×10 6 and 3.55×10 6 g/mol, respectively. As a high molecular weight polymer, HPAM can increase the viscosity of produced water (Horowitz et al., 2010, Gao, 2011, Kang et al., 2011).
Synthesis and evaluation of partially hydrolysed
solution was used. The hydrolyzed product (PHPA) was then recovered by precipitating in methanol and dried in vacuum oven for 5 h at 60°C. Molecular weight of polyacrylamide was determined by viscometric method!" where:1]: = 6.8 x 10-4 MnO.66• The intrinsic viscosity:1]: was determined at high shear rates after attaining the Newtonian behaviour.
