Sand Production Mechanism and Changes of Rock

2016-1-8  This chapter analyzes mechanism and factors influencing sand production. The reason for sand production by oil wells is that the original pressure balance around the wellbore is broken, resulting in yielding and original structure failure of formation rock. The mechanism of rock failure includes mechanical failure and chemical failure.

Sand Production an overview ScienceDirect Topics

Sand production from the reservoir is caused by the structural failure of borehole wall rock. The internal causes of sand production from the reservoir are the stress state of borehole wall rock and the tensile strength of rock (affected chiefly by consolidation strength of rock), whereas external causes are the producing pressure drawdown value and the change in reservoir fluid pressure.
