... is able to lower interface tension between oil and water, which able to carry oil inside rock pores into the production well, while polymer would be able to increase fluid viscosity and optimally drive the oil. Polymer is utilized as thickener to produce higher injection fluid viscosity, meanwhile polymer in the solution will form inter-polymer network [1] (Figure 1). Injection by using polymer to improve oil recovery was first introduced as Enhanced Oil Recovery in early 1960s. ...

... In the injection of biopolymers-chitosan there will be an interaction between the pore space of the rock and the injected biopolymer-chitosan particles. This interaction is referred to as adsorption which can cause biopolymer-chitosan particles to settle in the pores of the rock so that the pore space of the rock will shrink and the fluid flow rate will decrease [19]. The adsorption test is an important step to take because the results of this test chemical loss that occurs as a result of interaction between rocks and fluids can be known. ...
Writing this article aims to study the potential of shrimp shell waste to become a biopolymer that can be used in Enhanced Oil Recovery. Indonesia's oil production has decreased, one solution that can be done is Enhanced Oil Recovery, especially chemical injections in the form of polymers. Shrimp shell waste is quite abundant in Indonesia, but its utilization is not optimal. Shrimp shells contain chitin which can be processed into chitosan. Chitosan from shrimp shells can be developed as a biopolymer to increase the viscosity of water and reduce the mobility ratio of water and oil. The writing method used is to review several articles related to the processing of shrimp shells into chitosan biopolymer and polymer injection. Shrimp shell contains 15,33% chitin and the quality of the resulting chitosan has a Degree of Deacetylene (DD) value of 69,87%. Biopolymer obtained from the synthesis of shrimp shells can increase the viscosity of water and has the potential as an injection material in Enhanced Oil recovery, especially chemical injections that can increase the recovery of oil production.
... Polymer flooding has been shown to be effective in increasing oil recovery [2]. Polymers are used as thickeners that can increase the viscosity of the injection fluid [12][13][14]. By increasing the viscosity of the injection fluid, it can reduce the water-oil mobility ratio [6 and 15]. ...
... In the application of polymer injection in the field, the salinity of formation water must be considered before injection because salinity has a direct influence on the polymer solution [14]. Formation water has a salinity value ranging from 3,000 -300,000 mg/L [40] which contains dissolved ions in the form of cations (Na + , Ca2 + , Mg2 + , Ba2 + , Sr2 + , and Fe2 + ) and anions (Cl -, HCO2 -, and SO4 2-) [41 and 42]). ...

For polymer concentrations, a polymer is usually injected into the reservoir with a concentration of 250 to 2,000 mg/L [14]. In this study 4 concentrations were used, namely, 200, 500, 1,000, and 2,000 mg/L for both types of polymers (xanthan gum and polyacrylamide). ...

To improve the dispersion stability of phenol-formaldehyde resin (PFR) particles in simulated oilfield injection water and their propagation ability in petroleum reservoir, a hydrophobically associating polymer (HAP) was employed as a stabilizer in this paper. The dispersion stability of PFR in the injection water was studied by measuring turbidity as a function of time. In addition, the migration property of the PFR/HAP dispersion was evaluated by both cellulose membrane filtration and sand packs-flooding experiments. The results show that HAP can stabilize the PFR dispersion prepared with the simulated injection water by forming PFR/HAP complex molecular aggregates. These aggregates can migrate in sand packs with strong flow resistance due to deformation or disaggregation of the aggregates when passing through the pore throat. Oil recovery was improved by up to 21.1% on the basis of water flooding, and the higher the concentration of PFR/HAP dispersion system, the better the oil recovery effect. Moreover, the cycle of log-jamming/dispersion of the aggregates leads to their penetrations through the bigger pores in the sand packs with a higher flow resistance than water. This process can improve the conformance of water in high permeability sand packs on a micro/macro scale and thus divert more water into low permeability sand packs. Therefore, more oil could be recovered from the low permeability sand packs. Moreover, the bigger the sand pack’s permeability ratio, the lower the oil recovery rate by waterflood, and the more the incremental oil can be recovered by the PFR/HAP flood.
Polymer flooding is an Enhanced oil recovery (EOR) method using chemicals, such as xanthan gum and polyacrylamide which are widely used in the field. Polymer flooding can improve the mobility of the injection fluid, but in the reservoir the polymer has an interaction with sand known as adsorption which causes some of the polymer to be bound to the surface of the pore of sand, so that it has an impact on the ineffectiveness of the injection. The purpose of this study want to determine and compare the effect of sand grain on the adsorption of xanthan gum and polyacrylamide polymer solutions. Based on the experiment results, it was found that the increase in adsorption was proportional to the increase in polymer concentration. From two polymers used, xanthan gum showed lower adsorption than polyacrylamide. Based on the sand grain, the adsorption that occurs is greater in the grain size for large sand compare small.
