ABSTRACT:
The invention controls a well during completion by first running a sealable well completion tool and string downhole from the surface and isolating a productive interval near an oil or gas formation from the remainder of the wellbore. The drilling or other fluid in the interval is displaced from the interval under control by a non-damaging fluid. Using a pressure source from the surface, the non-damaging fluid is pressurized and circulated to move the gravel to the formation face by fluid entrainment. After the gravel is separated from the entraining fluid to form a gravel pack, the oil or gas formation may now be produced through the gravel pack.
