Abstract:

A method and system for processing a production stream containing a substantial amount of sand for continuously separating and disposing of the sand by re-injecting the sand into a subterranean formation. The production stream is flowed through a separator (e. g. hydrocyclone) which separates the sand from the stream. The sand is continuously discharged from the separator into an accumulator which, in turn, feeds the sand into an eductor in which, to form a slurry. The slurry is then re-injected into a subterranean formation, thereby continuously disposing of the sand.
