Abstract

Summary

Sand production is the migration of formation sand caused by the flow of reservoir fluids. This paper aims to develop an analytical model to predict sand production in oil field and validate it using 4 wells in Field “N”. Coupled sand failure mechanism considering static and dynamic criteria is used to models sand production. Rock particles strength is predominantly acting by drag and buoyancy forces. To capture fluid flow and pressure drop in porous medium, Darcy’s law is applied. The result of this study is the proposed analytical equation successfully models sand prediction accurately in 4 wells at range of cavity height 12–25 ft. At oil rate 1000 STB/day, calculated sand production in Well 1 is 0.005 lb/bbl, Well 2 is 0.007 lb/bbl, Well 3 is 0.005 lb/bbl, and Well 4 is 0.002 lb/bbl. This study shows good agreement on sand production trend in the moderate production rates of 2000 STB/day and low production rate of 500 STB/day with discrepancy varies of 2–3%. Sensitivity studies resulted is fluid viscosity and sand radius very sensitive to the sand production value. This study suggests cavity height in the proposed analytical method is applied at 10–25 ft.
