Oil and gas industries including lower carbon energy — Agents for chemical flooding — Test method for interfacial tension between surfactant-based chemical flooding system and oil

Scope

This document specifies a spinning drop method for measuring the interfacial tension between surfactant-based chemical flooding system and oil, especially for interfacial tension less than 10^-2 mN/m.

This document is applicable to surfactant-polymer (SP), alkali/salt-surfactant (AS), and alkali/salt-surfactant-polymer (ASP) flooding systems.

This document includes sections on principles, reagents and materials, instruments, procedures.
