... planning for completion design and later for production management. Unconsolidated and weakly consolidated sandstones are prone to fail at low flowing bottom hole pressures during hydrocarbon production. To predict the critical flowing bottom hole pressure for a safe (sand-free) drawdown, a geomechanical...
