- Production Of Rock Sand
Two key problems are commonly encountered when drilling oil and gas boreholes into poorly consolidated, clastic reservoir formations: (1) wellbore instability, caving, and partial collapse of the wellbore walls during drilling and subsequent fracturing and failure of the rock formations surrounding the wellbore during production; and (2) …

1. Introduction. The sand production prediction is one of the long-standing and complex problems in the petroleum industry [1].From the phenomenological viewpoint, sand production can occur when the formation do not present sufficient strength to withstand destabilizing forces generated during the flow of reservoir fluid [2], [3], [4].A …

Research performed in the early 1970s showed that rock failed and began to produce sand when the drawdown pressure was more than about 1.7 times the compressive strength. As an example, formation sand with a compressive strength of 1,000 psi would not fail or begin to produce sand until the drawdown exceeded 1,700 psi. ...
