The Adsorption Property of Wettability Reversal Surfactant p.2051 Study on Properties of Polyacrylamide Emulsion and Pilot Test of its Crosslinking System Used for EOR
Study of polyacrylamide-surfactant system on the water–oil interface properties and rheological properties for EOR. the emulsion formed by NP30 is more stable than others which were confirmed using phase behavior test. In fact, the emulsion formed by NP30 was remarkably stable against heat treatment and the passing of time. Conversely

The pilot test shows that after 2 months emulsion polymer injection, the bottomhole pressure of the production wells has increased by 1.48-1.79 MPa, the oil production from one correspondent well has increased from 28.67 t/d to 35.8 t/d, and the water content in the production flow has decreased from 52.3 % to 41.7%.
Experimental Study on the Physical Performance
Experimental Study on the Physical Performance and Flow Behavior of Decorated Polyacrylamide for Enhanced Oil Recovery Article (PDF Available) in Energies 12(3):562 · February 2025 with 78 Reads
Using polymer gel is still the mainstream technique of the chemical method for water shut-off in mature oilfield development. The gelation performance of polyethyleneimine (PEI) cross-linking partially hydrolyzed polyacrylamide (HPAM) gel was systematically investigated in this paper by using three types of molecular weight (Mw) HPAM. Results show that the gelant solution (the fluid solution
Main Controlling Factor of Polymer-Surfactant Flooding
This study aims to analyze the influence of viscosity and interfacial tension (IFT) on the recovery in heterogeneous reservoir and determines the main controlling factors of the polymer-surfactant (SP) flooding. The influence of the salinity and shearing action on the polymer viscosity and effects of the surfactant concentration on the IFT and emulsion behavior between chemical agent and oil
The paper only summarizes the major findings of that study Polyacrylamides might be provided as an emulsion in synthetic oil, with 50% active material, or as a powder with 90% active material. Whatever the type of polymer, a mother solution of high concentration (generally 5g/l) is prepared, and later diluted to the concentration of the design.
Experimental Study of Enhancing Oil Recovery with Weak
Experimental Study of Enhancing Oil Recovery with would benefit both the pilot test and industrial applica-tion. Inthispaper,strongalkaliisreplacedbyNa2 CO3.We wanted to determine the impact of Na2 CO3 on IFT and the polyacrylamide molecular chain is in a stretch state
Rand found that the Alkaline/Surfactant/Polymer could effectively enhance oil recovery [1].It was the earliest study on ASP flooding. After that, ASP flooding has been reported and applied widely around the world [2 – 4].The field test conducted in Daqing oil field revealed the oil recovery of ASP flooding is 20% higher than water flooding [5].ASP flooding was considered as an effective
Critical review of alkaline-polymer flooding
Field performance shows that the incremental oil recovery factor from alkaline projects was low. Chemical EOR experience tells us that the mobility control is very important. Thus, the combination of alkaline flooding and polymer flooding is expected to improve alkaline flooding performance. This paper is to provide a critical review of alkaline-polymer (AP) flooding.

- Is polyacrylamide contaminated with acrylamide?
- Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
