Identification of minimum transport condition for sand in two-phase flow using acoustic emission technology

This paper presents an experimental investigation using Acoustic Emission (AE) technology to monitor sand transport characteristics and identify the sand minimum transport condition (MTC) in two-phase flow. The sand concentration investigated ranged from 300 lb/1000 bbl to 700 lb/1000 bbl and superficial liquid velocity (VSL) had a range of between 0.1 ms−1 and 1.2 ms−1. The experimental findings clearly showed a correlation between MTC and AE energy levels.
