Review of Sand Production Prediction Models

Sand production in oil and gas wells can occur if fluid flow exceeds a certain threshold governed by factors such as consistency of the reservoir rock, stress state and the type of completion used around the well. The amount of solids can be less than a few grams per cubic meter of reservoir fluid, posing only minor problems, or a substantial amount over a short period of time, resulting in ...THE UNIAXIAL COMPRESSIVE STRENGTH OF SOFT ROCKD S Agustawijaya / The Uniaxial Compressive Strength of Soft Rock / CED, Vol. 9, No. 1, 9–14, March. 2007 10 use of hand sculpturing and fine sandpaper to flatten the ends of the friable core specimen.
