CTAB grafted PAM gel and its application in drilling fluid
1. Introduction. Drilling fluid (Mud) is one key fluid for any oil and gas earth excavation process. Mud assists the drilling process by stabilizing the well bore, transmitting the hydraulic power, lifting the cuttings and providing lubrication etc. Minimizing the amount of fluid filtrate invasion into the formation is one of the important functions of drilling fluids.
Polyacrylamide (PAM), the white granular in appearance, can be divided into three types, they are Anionic Polyacrylamide, Cationic Polyacrylamide and Nonionic Polyacrylamide. Although these PAM chemicals are mainly used for water treatment, they also have other different applications.
- What are cationic polyacrylamide copolymers?
- Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
- Are cationic polyacrylamide copolymers harmful to the environment?
- Environ Sci Eur. 2018; 30 (1): 16. Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- Do cationic polyacrylamide copolymers degrade in soil after land-spreading?
- This project demonstrated that the synthetic cationic polyacrylamide copolymers (PAMs) incorporating C–C-bonds in the main chain slowly degrade in soil after land-spreading as a component of MWWTP sludge.
