Correlation Between an Acoustic Sand Monitor Output With
Particle Impact Velocity and Sand Production Rate
Mohammad Maqsud Ali, Master’s Candidate, Mechanical Engineering

Sand production control is a major problem as well as a concern for the oil and gas industry. Entrained sand inside various fittings in sand producing environments can cause erosional damage that in turn leads to production losses, high operating cost and lower operating efficiency. The most important factors that control erosional damage are high sand production rates and particle impact velocity. By using a properly calibrated sand monitor, these two important factors can be addressed. A commercially available acoustic type sand monitor was investigated in quantifying the amount of sand and evaluation of particle impact velocity in different single-phase and multiphase flow conditions. In the present research work, the output data from the sand monitor were gathered and analyzed in a test section of a flow loop. These data were used to generate a graph that will help to quantify the amount of sand in different flow conditions. The sand probe output data were also used to develop a semi-empirical curve that can calculate the particle impact velocity. The results obtained from the sand monitor indicate that there is a direct correlation among sand probe output, sand production rate and particle impact velocity.
