The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative number of sites vary depending on surface charge

partially hydrolyzed polyacrylamide: enhanced oil recovery

Partially hydrolyzed polyacrylamide: enhanced oil recovery

Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery. However, during such enhanced oil recovery (EOR) operations, it also produces a huge quantity of water alongside oil. Depending

The anionic polyacrylamide concentration was 0.1¨C0.2 wt%, such that the concentration is well above C* (critical overlap concentration) and below C** (critical entanglement concentration). The concentration of shale was kept constant at 0.5 lb/bbl, and the concentration of anionic polyacrylamide was varied from 0.1 to 0.2 wt%.

Whether before or after aging, when the amount of polymer was gradually increased, the filtration loss of drilling fluid showed a downward trend, when no polymer was added, the API filtration loss of the base slurry before aging was 17 mL, and after aging, it surged to 37 mL, which was due to the high temperature action destroying the cementation effect of bentonite itself, resulting in an

Synthesis of novel modified acrylamide copolymers for montmorillonite

A study was conducted to treat the water-based drilling fluid through coagulation-flocculation. Innovative modified acrylamide copolymers were utilized as montmorillonite flocculants to improve drilling performance and reduce environmental contamination. A series of acrylamide copolymers was prepared by in situ free radical polymerization in aqueous medium using ammonium persulfate as a

Development of a Low-Molecular-Weight Filtrate Reducer with High

Water-based drilling fluids have been increasingly adopted in oil and gas drilling because of their low cost and environmental impact [1,2,3,4]. Water-based drilling fluids comprise water, bentonite, and other functional additives [5,6,7]. Drilling fluid is a general term for circulating fluids that meet the needs of drilling work with various
