Nagre, R. D. published the artcileSynthesis and assessment of a hydrophobically associating heteropolymer in water-based mud, HPLC of Formula: 142-90-5, the main research area is acrylamide HEMA lauryl methacrylate AMPS copolymer drilling fluid.
Water-soluble polymers can be used as key ingredients of both drilling fluids for virgin fields and polymer-enhanced oil recovery in underperforming reservoirs. The efficacy of hydrophobically associating heteropolymer (HAH-polymer) as an agent for petroleum resource recovery was examined in this study. The hydrophobically associating heteropolymer (HAH-polymer) comprising acrylamide, sodium 2-acrylamido-2-methylpropanesulfonate, hydroxyethyl methacrylate and lauryl methacrylate was synthesized in micellar medium by free-radical polymerization The hydrophobically associating heteropolymer (HAH-polymer) was characterized by FTIR and 1H NMR spectral analyses. The effects of temperature, pH and shear on the solution behavior of the HAH-polymer were also examined Rheol. and fluid loss properties of HAH-polymer-incorporated water-based drilling fluids were assessed. The HAH-polymer improved the thermal stability between 25 and 160° of the drilling mud and maintained mud fluid loss of 8.4-8.6 cm3 compared with the polymer-free blank of 43.5-107.0 cm3. In a salt-contaminated mud, the heteropolymer enhanced rheol. properties and significantly reduced API filtration loss to 7.6-8.8 cm3 after hot aging between 25 and 150°. Under high temperature-high pressure filtration testing of muds, the HAH-polymer demonstrated excellent fluid loss reduction by providing about eightfold fluid loss control (14.7 cm3) compared to the polymer-free blank (113.2 cm3) at 150°.
