The shape and size of sand grains, as well as the saturating fluid, influence the mechanical properties of unconsolidated sands and need to be considered in frac-pack design.
These mechanical properties of unconsolidated sands play an important role in determining the geometry of frac-pack treatments.
Stress-strain curves obtained for unconsolidated sands at elevated stresses show highly nonlinear hysteretic behavior. The impact of these findings on frac-pack design can be significant.
The nonlinear elastic properties of unconsolidated sand can giv...
