A Mechanistic Model for Horizontal Gravel Pack Displacement
For displacement calculation purposes, the horizontal well gravel pack operation can be divided in three different stages: the injection, the alpha wave propagation and the beta wave propagation. The injection stage, as highlighted in Fig. 1, consists of pumping a fluid-gravel mixture through the pipe until a cross over tool where the flow ...

Numerical Simulation of Pulsed Gravel Packing Completion in Horizontal ...
The gravel packing completion method for horizontal wells has the advantages of maintaining high oil production for a long time, maintaining wellbore stability, and preventing sand production, so it has become the preferred completion method for horizontal wells. At present, this technology still faces the problems of high sand bed height and poor gravel migration.
