Sand control OilfieldWiki

The general procedure followed by most operators considering whether or not sand control is required, is to determine the hardness of the formation rock (i.e., the rock's compressive strength). Since the rock's compressive strength has the same units as the pressure drawdown in the reservoir, the two parameters can be compared on a one to one basis and drawdown limits for specific wells can be determined.
