Abstract: Sand production occurs during the hydrocarbon production from a well when the reservoir sandstone is weak enough to fail under the in-situ stress conditions and the imposed stress changes due to the hydrocarbon production. A 3D Numerical Geomechanical Model of Greater Ughelli Depobelt in the Niger Delta was analysed by assessing the mechanical response to rock. This was done through the analysis and modelling of information from offset data. The developed model is capable of assessing the conditions that lead to the onset of sanding, the rate of sanding and the volume of sand that would be produced.
