00 Sand Production Prediction in Petroleum Industry Using Finite Element Method Hossein Shafii Esfidvajany h shafii@me iut ac ir Date of Submission 2015 06 28 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Mahdi Shirani m shirani@cc iut ac irAbstract A significant proportion of the world oil and gas reserves is contained in weaklyconsolidated sandstone reservoirs and hence is prone to sand production Sand production oftenoccurs in the petroleum industry as the result of erosion in reservoir sandstones duringhydrocarbon production Sand production is the cause of many problems in the oil industry andit affects the completion adversely These problems include but are not limited to pluggingthe perforations or production liner wellbore instability failure of sand control completions additional cost of remedial and cleanup operations and pipelines and surface facilities erosion Pressure of upper layers of the earth and the force of locking the earth layers together andhydrodynamic stress caused by the pressure gradient of oil and gas flow cause failure anderosion of the sandstone Sand production is an important research filed in the oil industry andsand production in hydrocarbon reservoirs imposes considerable cost on oil companies everyyear That s over a several million dollars a year in Iran The main goal of this thesis is theevaluation of pore pressure and stresses impact on volumetric rate of sand production Thisresearch describes the physical and hydraulic properties of porous stone s Sand productionprediction models are introduced and described The erosion model of rock is derived Erosionmodel described by an erosion equation that developed by a code in UMESHMOTIONsubroutine To simulate three dimensional erosion model in ABAQUS UMESHMOTIONsubroutine was linked to arbitrary Lagrangian Eulerian ALE domain of the model that proneto erosion to simulate 3D erosion and ablation of materials An experimental model was chosento compare with ABAQUS simulation results Different pore pressures and mechanical In situstresses are applied and the sand production is calculated and compared with availableexperimental data The results show that increase on pore pressure and in situ stresses leads toincrease in volumetric rate of sand production The model was simulated with three differentrock strengths and the results show decrease in sand production with increase on rock strength A different erosion model was chosen and a 3D wellbore model s of Ahwaz Bangestan wellborewas used to simulate sand production Wellbore model was simulated with different in situstresses and the results are reported Keywords Sand Production Erosion Model Porous Media In Situ stress ABAQUS UMESHMOTION
