Conclusions A novel high-molecular-weight amphoteric terpolymer (TPA), composed of 80 mol. acrylamide (AAm) (a nonionic monomer), 10 mol. 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS) (an anionic monomer), and 10 mol. (3-acrylamidopropyl) trimethylammonium chloride (APTAC) (a cationic monomer), was effectively tested as an oil displacement agent for polymer flooding experiments. The rheological research demonstrated that the viscosity of TPA is steady inside the selection of 20000 g -1 brine salinityPolymers 2022, 14,12 ofat 24 and 60 C, whereas the viscosity in the HPAM option drops drastically upon escalating the salinity. In addition, the TPA solution was shown to become a lot more resilient to viscosity reduction just after aging at area temperature than was HPAM. Indeed, following 15 days of aging, a viscosity reduction of 18.2 occurred in TPA, which is substantially reduce than the 27.5 in HPAM. Sand-pack and core flooding experiments offered useful final results. In unique, the efficiency of HPAM at relatively low salinity (15 g -1 NaCl) was established by its greater incremental oil recovery of five right after pre-flushing the model with 3 PVs of brine and numerous TPA options, which themselves had established comparatively ineffective at that degree of salinity. Within the core flooding tests, HPAM also outperformed TPA in 163 g -1 brine, which was considered to be moderate salinity for this study. Having said that, when the brine salinity was enhanced to 200 g -1 , the TPA allowed the production of 2 instances a lot more oil at its maximum than did HPAM. This obtaining adds towards the novelty and significance of this operate and is explained by the higher apparent viscosity from the TPA solution in the porous media, which was indicated by stress drops of 2 times. Therefore, ternary polyampholyte (TPA), having each cationic and anionic groups, resulting inside the attraction in between positively and negatively charged groups getting screened out by low-molecularweight ions in brines, causes the polymer chain to expand, top to a viscosifying effect in clear demonstration from the rewards with the antipolyelectrolyte effect on EOR.OSM Protein web Author Contributions: I.Annexin V-PE Apoptosis Detection Kit ProtocolDocumentation S.PMID:24487575 G.: sand pack and core flooding, and original draft preparation; N.M.: viscosity measurements, formal analysis; A.V.S.: polymer synthesis and original draft preparation; S.E.K.: supervision, project administration, funding acquisition.
