ABSTRACT:
A method and apparatus are provided for injection of fluid within a subterranean well for treatment of a production zone within a subterranean well by first initiating flow of treatment fluid into one of uppermost and lowermost portions of the zone and by subsequent continuation of flow of treatment fluid into the other of the uppermost and lowermost portion of the zone. A conduit is assembled which carries a zone isolator, and fluid communicating means having first and second communicating members. The conduit is run into the well until the isolator is set above the zone and the first communicating member is in proximity to the uppermost end of the zone and the second communicating member is in proximity to the lowermost end of the production zone. A first injection flow path is formed for the fluid which extends from the top of the well through the interior of the communicating means and out only the exterior of the second communicating member and into the lowermost end of the zone. A second injection path is thereafter formed for said fluid and extends from the top of the well through the interior only the first communicating member of the communicating means while the fluid is prevented from passing from the interior to the exterior of the second communicating member, the second injection path for the fluid continuing out of the first communicating member and into the other end of the zone. With the zone isolator still in place, gravel packing of the well may be thereafter effected.
