Method for sweeping solids or displacing a fluid in a wellbore

摘要: A method and system for removing solids or displacing a fluid from wellbore wherein plurality of resilient rubber-like flexible reticulated open cell foam elements are dispersed in pumped through drill pipe into the annulus between pipe. In annulus, impact dislodge such as proppants, gravels, drilled cuttings other to be displaced etc. carried by containing back surface different location wellbore.
