Preformed particle gels (PPGs) based on acrylamide (AAm), (3-acrylamidopropyl) trimethylammonium chloride (APTAC), and 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS) were synthesized via conventional free radical copolymerization. The resultant PPGs of various compositions characterized using FTIR spectroscopy, TG DT analysis, mechanical testing. swelling behavior depending ionic strength, temperature, degree crosslinking, pH was also studied. obtained results show that the...
Excessive reservoir water poses significant challenges in the oil and gas industry by diminishing hydrocarbon recovery efficiency generating environmental economic complications. Conventional polymer flooding techniques, although beneficial, often prove inadequate under conditions of elevated temperature salinity, highlighting need for more resilient materials. In this research, two types acrylamide-based preformed particle gels (PPGs) were synthesized, as follows: polyelectrolyte...
Polyampholyte nanogels based on N-isopropylacrylamide (NIPAM), (3-acrylamidopropyl) trimethylammonium chloride (APTAC) and 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS) were synthesized via conventional redox-initiated free radical copolymerization. The resultant of various compositions, specifically [NIPAM]:[APTAC]:[AMPS] = 90:5:5; 90:7.5:2.5; 90:2.5:7.5 mol.%, herein abbreviated as NIPAM90-APTAC5-AMPS5, NIPAM90-APTAC7.5-AMPS2.5 NIPAM90-APTAC2.5-AMPS7.5, characterized by a...
Abstract Amphoteric nano‐ and microgels based on acrylamide (AAm), 3‐acrylamidopropyltrimethylammonium chloride (APTAC) 2‐acrylamido‐2‐propanesulfonate sodium salt (AMPS) were prepared via inverse emulsion polymerization in the presence of crosslinking agent— N , ′‐methylenebisacrylamide (MBAA). Several polyampholyte microgel samples AAm‐APTAC‐AMPS with compositions (70:15:15, 80:10:10, 90:5:5 mol%) obtained they abbreviated as AAm 70 ‐APTAC 15 ‐AMPS 80 10 90 5 (where lower indexes indicate...

This study investigates the efficacy of high molecular weight hydrolyzed polyacrylamide (HPAM) solutions in enhancing oil recovery under salinity conditions. The viscosity values 0.25 wt.% HPAM 250 g∙L─1 brine with content divalent cations (Ca and Mg) were found to range from 11.5 12.6 cP for both 10% 30% hydrolysis polymers. displacement 420-cP sand pack models showed that injecting 3 pore volumes (PVs) polymer significantly increased factor, an increment 16─28% after injection 1 PV water....
