... rates and if the producing condition will make the well production acceptable. There are a few factors influencing the tendency of a well for sand production, such as degree of consolidation of the formation, production rate of the reservoir fluids, pressure drawdown, reduction of the pore pressure...

... and thus delaying tensile rock failure and fluidization. At the same time, wormholes may affect the stability of the near wellbore region, having thus a negative effect on the critical drawdown. An experimental program has been carried out to study the effect of wormholing on the critical drawdown...

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...

Aside from including cement and casing as structural elements, the modelling incorporated a subsurface u stress model, geological horizons from a full-field geomodel, and pore pressure profiles from a reservoir simulator. The goal was to define specific failure onset time...
