Method and apparatus for gravel packing multiple zones |
| abstract |
ABSTRACT A method of gravel packing multiple zones with a single trip of the operating string into a well without inducing fluid movement across zones, and without dis-turbing the zone being packed in reverse circulation. Apparatus is disclosed to perform the method, comprising a screen liner assembly surrounding a concentric operat-ing string. Mechanical force on the operating string is used to change all tool modes of the apparatus. The operating string is accurately positioned with respect to the screen liner assembly at every zone level and zones may be easily relocated if necessary. Zones may be packed in any order, and a zone may be repacked, if necessary, during the same trip into the well. |
