Abstracts

Sand production is a serious problem during oil and gas production in unconsolidated sandstone formations. It can rapidly damage downhole and surface equipment. Therefore, oil and gas contractors constantly seek methods to control sand production. However, in unconsolidated sandstone formations, sand production typically occurs during the later stages of production. Some wells encountered sand production from the beginning stage, while others could be produced without having sand production if managed properly. This indicates that sand production is influenced by both reservoir properties and well production operating conditions. Reservoir properties can be determined during the exploration phase. Additionally, several researchers have demonstrated that sand production mechanisms are linked to these reservoir parameters. In this paper, we employ a geomechanical model to predict the critical reservoir pressure and critical drawdown pressure values leading to sand intrusion and subsequently propose well completion strategies of Expandable Sand Screens to prevent sand production and optimise production performance processes to enhance the efficiency of oil and gas exploitation investments. The accurate assessment of sand occurrence in production process potential enables investors to make mindful decisions regarding sand control measures for specific wells. Sand control is an expensive and risky undertaking; however, it is crucial for wells with high sand production potential to prevent damage to surface equipment and operational complications caused by sand.
