Biodegradation of Partially Hydrolyzed Polyacrylamide HPAM
Biodegradation of partially hydrolyzed polyacrylamide by bacteria isolated from production water after polymer flooding in an oil field. Journal of Hazardous Materials 184(1–3): 105–110.
In this work, the effect of partially hydrolyzed polyacrylamide (HPAM) on the oil–water interfacial properties of produced water from polymer flooding (PWPF) was investigated. In addition, this study investigated the effects of three fiocculants (polyaluminium chloride PAC, cationic polymer FO4800SH, and nonionic polymer 402) on the stability
Viscosity of partially hydrolyzed polyacrylamide under
For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely-used polymer. HPAM solution must maintain high viscosity to effectively mobilize oil.
Polymer flood using partially hydrolyzed polyacrylamide (HPAM) has been proven to be an effective method to increase oil recovery. However, when HPAM breaks through the reservoir and shows up in the produced fluids, it brings unique emulsion characteristics and challenges to the separation processes.
Oil Field Partially Hydrolyzed Polyacrylamide, Oil Field
We offers 135 oil field partially hydrolyzed polyacrylamide products. About 29% of these are petroleum additives, 24% are paper chemicals, and 18% are water treatment chemicals. A wide variety of oil field partially hydrolyzed polyacrylamide options are available to you, such as coating auxiliary agents, water treatment chemicals, and paper chemicals.
Commonly, two types of polymers have been utilized in EOR applications: synthetic polymers, primarily partially hydrolyzed polyacrylamide (HPAM), and biopolymers, mainly xanthan. Both polymers are used as viscosifying agents . Wang, et al. reported the success of polymer flooding in increasing oil recovery factor of Daqing oil field in China.
Analysis and simulation of polymer injectivity — Heriot
Generic field data were used to design a near-well sector and a high molecular weight partially hydrolyzed polyacrylamide (HPAM) was used as polymer reference. Here, the influence of different polymer rheological behaviors on BHP and BHP-transient was analyzed and identified.
unfiltered partially hydrolysed polyacrylamide (HPAM) solutions for wide range of polymer concentrations (125‐5000 ppm) and salinities (5‐20 g/L) in high permeability sandstones. Data from rheological measurements and single phase linear core flood
Polymer Flow in Porous Media: Relevance to Enhanced Oil
Partially-hydrolyzed Flopaam 3630S at 500 ppm and 1500 ppm was injected into the cores and the in-situ rheology of the polymer solutions was measured. The two concentrations were chosen to give viscosities representative of the upper and lower limit of what would be economically viable for polymer flooding in an oil field.
The dynamic interfacial tension between crude oil and the partially hydrolyzed polyacrylamide (HPAM)/sodium oleate (C17H33COONa) mixed soln. in the presence of sodium halide (NaX: X = F, Cl, Br, I) was studied by TX500C interfacial tensiometer, and the viscosity of the mixed soln. was studied by DV-iii ultra programmable rheometer.
