Improving oil recovery in Kazakhstan oilfields by using polyacrylamide [PDF]

, 2009
This research presents a cross-linked polymer system (CPS), which is classified as a gel. Cross-linked polymers can be used in chemical enhanced oil recovery as an in-depth profile regulation agent, and at the same time as an oil dislocation agent in a ...

A Porous Interfacial Photothermal Layer of Fused Core–Shell Carbon‐Polymer Nanospheres for Directional Salt Crystallization and Zero‐Liquid‐Discharge

Advanced Materials, EarlyView.
A hierarchical hydrogel evaporator with a thin, porous photothermal layer of fused core–shell carbon‐polymer nanospheres enables ultrafast interfacial solar evaporation with minimized heat loss and sufficient water supply. Directional advection‐dominated brine transport, coupled with Marangoni‐driven interfacial flow, drives salt away from the active ...

Numerical Simulation and Flotation Unit Structural Optimization of Dissolved Air Flotation–Sedimentation Tank for Oilfield Alkali/Surfactant/Polymer (ASP)-Flooding Produced Water

Energies
The low separation efficiency of alkali/surfactant/polymer (ASP)-flooding-produced water, attributed to its high emulsification, high viscosity, and surfactant enrichment, presents a significant treatment challenge.

Can We Ignore Asphaltenes in a Gas Injection Project for Light-Oils?

, 2003
SPE Paper 84877When light-oil reservoirs are considered for miscible gas injection processes (with CO2 or hydrocarbon gases), more often the potential of asphaltene precipitation is either overlooked or not anticipated for two seemingly compelling ...
