Vast majority of the world’s petroleum reserves are found in poorly consolidated or unconsolidated formations, which are prone to sand production, requires millions of dollars each year for operational expenditures. Similarly, oilfields confined to the shallow sandstone reservoirs in Kazakhstan, such as Karazhanbas, North Buzachi, Kenkiak, Moldabek and others have sand production problem. Despite extensive research had been conducted on sand production problem, the exact mechanisms are still not fully understood. The aim of the project is to study the effect of flow on sand production process from a hole in a weak sandstone sample using numerical methods and experimental tools. Sand production experiments on artificial sandstones will be conducted to replicate reservoir conditions. Numerical modeling of porous media using coupled technique of Discrete-Element-Method (DEM) and Computational-Fluid-Dynamics (CFD) will be used to model a sand production behavior in a weak sandstone.
