An adsorption equation calibrated to experimental data is then used to determine an amount of soda pseudo-constituent adsorbed, from the concentration of the soda pseudo-constituent. Finally, the evolution of the pH value is modelled by modelling the transport of the alkaline agent solution by means of a soda transport simulator, by replacing the soda by the soda pseudo-constituent."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of determining an amount of alkaline agent to be injected within the context of enhanced oil recovery","description":"Method of modelling the evolution of the pH value of a porous medium after injection of an alkaline agent solution into this medium.The alkaline agent is considered as a soda pseudo-constituent of con","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9785802","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
