PAMs have been widely applied in oil drilling industry :

1. EOR(tertiary oil recovery)
Enhace oil recovery (tertiary oil recovery): this requires the high molecular weight PAM with high viscosity .  Ordinary product can resist a temperature up to 75℃ and a salinity up to 30,000 ppm. Salt-tolerant products can resist a temperature up to 90℃ and a salinity up to 30,000 ppm.

Product  name	Product appearance	Molecular weight(million)	Ionic charges (%)	Dissolution time(min)	Solid content (%)	Charge type
FA series	White granular	8-30	20-35	＜60	＞90	Anionic

2. DRILLING FLUID PAM

In drilling fluid ,PAM is applied to adjust clay swelling , dilution of bentonite ,etc.

FA series	White granular	3-20	20-40	＜60	＞90	Anionic
AFE series	Emulsion	8-20	20-40	＜30	35-45	Anionic

3. PROFILE- MODIFYING /WATER SHUTOFF AGENT

Drilling  conformation : to increase the oil production while reducing the water out-coming .

4. Oily waste water treatment

PAM can used to separate the oil and the water .

5． DRAG REDUCTION AGENT

High molecular weight PAM with medium ion-degree could obviously reduce the frictional resistance in the  transmitting tubes.
