Use of ultra lightweight particulates in multi-path gravel packing operations |
| abstract |
A well penetrating a subterranean formation may be subjected to a multi-path gravel packing operation by using a fluid containing an ultra lightweight particulate having an apparent specific gravity less than or equal to 2.45 which is substantially neutrally buoyant in a carrier fluid. The fluid is flowed through one or more transport tubes which, with a gravel packing screen, constitute a screen assembly. A gravel pack is formed onto the screen of the screen assembly in-situ. |
