The near wellbore region is subjected to cyclic loads due to repeated changes of the mean effective stress. These repeated loads result in plastic deformation and sanding problems which can occur in injection or production wells. The difficulty is more pronounced in weakly consolidated reservoirs...
Sand Rate Model and Data Processing Method for non-Instructive Ultrasonic Sand Monitoring in Flow PipelineDownload
Sand production is a critical issue during oil and gas production from sandstone reservoirs. Uncontrolled sand production not only poses the risk of well failure, but also can cause extensive damage to surface and subsurface facilities such as tubing, pumps, valves and pipelines. In recent...
The Discrete Element Method (DEM) has been developed and used in modelling dry granular materials with or without cohesive bonding between particles. The incorporation of fluid flow in the DEM analysis is difficult since the DEM is a discrete approach to mechanistic analysis while fluid is a...
