Well preparation for gravel packing
Push pill volumes should at least be equal to a volume of 300 ft of work string-casing annulus and have the same density as the drill-in fluid and a yield point that is 1.5 to 2.0 times that of the drill-in fluid. Thus, they are easily made from a portion of the drill-in mud by the addition of a viscosifier to raise the yield point.Casing sweeps depend on …
