  • 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.

    Petropedia What is Sand Production? Definition from

    Sand Production is the migration of the formation sand induced by the flow of reservoir fluids. It is initiated when the rocks around the perforations fail and the fluids thrust the loose grains into the borehole. It takes place when the reservoir fluid flow outpaces an assertive threshold which depends on factors like stress state, reservoir rock

    Sand Production Mechanism and Changes of Rock
