Silica Nanofluids in an Oilfield Polymer Polyacrylamide
Silica nanofluids in polyacrylamide with and without surfactant: Viscosity, surface tension, and interfacial tension with liquid paraffin. Journal of Petroleum Science and Engineering 2017, 152, 575-585. DOI: 10.1016/j.petrol.2017.01.039.
Oil production from matured crude oil reservoirs is still associated with low recovery factors. Chemical enhanced oil recovery (EOR) is one of the techniques which can significantly improve the recovery factor of the trapped oil. This is mainly achieved by lowering the interfacial tension (IFT) of the crude oil–brine/aqueous chemical and increasing the viscosity of the injected fluid.
Interfacial properties of polyacrylamide solutions
Surface tension of the polyacrylamide solution was measured as a function of the polyacrylamide concentration (0–1000 gm/m 3) and temperature (10–60°C).The static contact angles of the polyacrylamide solutions in the range of 0–1000 gm/m 3 were reported on the polyvinyl chloride and Teflon substrates. Surface tension, static contact angle, and spreading behavior of the polyacrylamide

Interfacial dilational viscoelastic properties
The change of interfacial viscoelasticity along with measuring time, the effect of polymer concentration and the type of polymer on interfacial viscoelasticity at the interface between polymer and dodecane were investigated by means of dilatational method. Moreover different viscoelasticity at different interfaces for polymer solution was also found. The result shows that the response of ...

Silica nanofluids in polyacrylamide with and without
Despite several studies on interfacial properties of nanofluid, previous studies focused on the use of nanofluid without EOR polymer of polyacrylamide (PAM) (Saleh et al., 2005, Hendraningrat and Shidong, 2012, ShamsiJazeyi et al., 2014, Zargartalebi et al., 2015), and only limited information is available on the preparation of nanofluid in PAM

Effect of Surfactant-Polymer Interaction
The interfacial tensions between a Saudi Arabian crude oil and the SP formulations consisting of surfactant and polymer in different concentrations were investigated at 30 and 90°C for each system. The effects of surfactant-polymer interaction on the interfacial properties were similar for the two systems.

polyacrylamide solution. After conducting several tests of polymer and nanoparticle mixture, we add cationic surfactants with these solutions. It is also observed that above 1.0wt% of a nanoparticle of SiO 2 and TiO 2 (except Fe 2 O 3), the solution of polymer and Gemini surfactants gets precipitated. This will set the limit and we add the
