Abstract:
The purpose of this study was the production of copolymers with highly hydrophilic-hydrophobic properties, using inexpensive and available monomers as potential enhancing oil recovery (EOR) and water production control agents for high-temperature and high-salinity (HTHS) oil reservoirs. To overcome these problems, new types of microstructures based on modified acrylamide with hydrophobic groups (alpha-methyl styrene monomer) using inversible mini-emulsion were synthesized. The structure of the synthesized copolymer was investigated using methods of FT-IR. The micro-structure and the particle-size of the copolymer particles were studied with the scanning electron microscopy (FE-SEM). As well, the rheological properties and behavior of the synthesized copolymer solution under high temperature and salinity conditions using rotary viscometer and rheometric measurements spectrum (RMS).
