Hydraulic formation packing

Abstract

Abstract A WELL AND METHOD OF COMPLETING SAME CHARACTERIZED BY FORCING POROUS PELLETS INTO A NONFRACTURABLE FORMATION OF UNCONSOLIDATED, UNCEMENTED PARTICLES WHICH ARE SUFFICIENTLY MOBILE TO BE COMPACTED OUTWARDLY FROM THE WELL, THUS FORMING AN ARTIFICIAL VOLUME BETWEEN THE WELL BORE AND A NEW ENVELOPE OF COMPACTED PARTICLES, THE VOLUME BEING FILLED WITH THE PELLETS, REPLACING THE ORIGINAL PARTICLES, AND FORMING A PERMEABLE BED THROUGH WHICH FLUID MAY FLOW THROUGH THE ENVELOPE AND PELLET BED TO THE WELL BORE OR CASING IN SAME. SINCE THE AREA OF THE NEW ENVELOPE IS CONSIDERABLY IN EXCESS OF THE ENVELOPE OF THE ORIGINAL UNCOMPACTED PARTICLES, INCREASED FLUID PRODUCTION IS THUS ATTAINED. ALSO, SINCE THE RATE OF MOVEMENT OF FLUID ACROSS THE UNIT AREA OF THE SURROUNDING DRAINAGE ENVELOPE AREA OF THE PELLET BED MAY THUS BE MATERIALLY INCREASED OVER THE ORIGINAL DRAINAGE AREA OF THE PARTICLE BED IMMEDIATELY SURROUNDING THE WELL BORE, THE TENDENCY OF THE FORMATION PARTICLES TO MIGRATE THROUGH THE BED IS REDUCED, THUS REDUCING TENDENCY TO SAND OR CLOG THE CASING OR PUMPING APPARATUS CONTAINED IN SAME.
