Sand erosion in the oil and natural gas industry causes damage to pipes and equipment which can lead to production shutdown and significant economic losses. Gas dominant flows are common in gas production so a firm understanding of sand erosion in these flow conditions is vital to ensure continuous production. Experiments were conducted mainly on a large scale multiphase 3-inch and 4-inch flow loop using Electrical Resistance (ER) erosion probes to monitor real-time erosion. Generally increasing the superficial gas velocity increases the erosion rate while increasing the superficial liquid velocity decreases the erosion rate. The effect of sand size pipe size flow orientation and probe location on erosion was also examined. But there are many situations that these probes do not detect sand erosion for certain gas and liquid conditions and probe placement. Additionally temperature changes can obscure ER probe data. Understanding erosion rate in gas dominant flows can help engineers determine the appropriate production rate in the field and initiate inspection and operation plans to ensure safety and continuous production.
