Dose optimization of oil field produced water and advanced water treatment for heavy viscous oil
Published in Elsevier Ltd
The treatment and disposal of oil field-produced water from pay zones presents a variety of issues for the hydrocarbon industry. Significant laboratory experimentation is carried out in this research program to design optimized dosages of oil field chemicals to design a water treatment plant for a thin stacked reservoir containing heavy viscous oil. When produced water is produced by pay zones containing heavy viscous oil, treatment can be difficult. For a better understanding of treatment procedures, chemical properties and physical properties of produced water are analysed. For re-injection of producing water to maintain reservoir pressure, the produced water must be compatible with the rheology of the reservoir under study. If the water leaving oil fields is untreated, it creates problems with injectivity loss and formation degradation, contaminating local groundwater resources and causing a significant environmental disaster. When significant amounts of oil field water is generated, the cost of water treatment chemicals rises dramatically. As a result, after examining the ionic concentration of generated water, this research effort recommends optimizing chemical dosing. Various filtration tests for effective rock fluid compatibility, include series, care, and coarse. The entire water treatment system was designed on prescribed treatment chemical dosages. The primary phase of generated water purification in this study relies heavily on the water treatment technologies of coagulation and flocculation. This processed oil field-produced water is ideal for Enhanced Oil Recovery such as Alkali Surfactant-Polymer flooding. © 2023 Elsevier Ltd. All rights reserved.
