Tool For Blocking Axial Flow In Gravel-Packed Well Annulus
US Patent:
5588487, Dec 31, 1996
Filed:
Sep 12, 1995
Appl. No.:
8/527116
Inventors:
David W. Bryant - Abita Springs LA
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
E21B 4304, E21B 4308
US Classification:
166 51
Abstract:
A well screen for gravel-packing a wellbore interval comprising at least two joints connected by a well tool. Each joint is comprised of a length of screen section which has at least one, axially-extending shunt conduit thereon for carrying gravel slurry to different levels within the interval. The well tool has at least one by-pass tube therein which is adapted to align with and fluidly-connect the shunt conduits on respective joints whereby gravel can flow from one of the shunt conduit, through the by-pass tube, and into and out of the other shunt conduit. A packing means is mounted on the tool for preventing any substantial annular, axial flow past the tool when the tool is an operable position within the wellbore.
Method For Removing A Gravel Pack Screen
US Patent:

Filed:
Apr 8, 1997
Appl. No.:

Inventors:
David Wade Bryant - Abita Springs LA
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
E21B 3708
US Classification:
166311
Abstract:
A method for removing a gravel-pack screen from a wellbore. of a well which has been "gravel packed". When it is desired to remove the screen from the wellbore, a washstring is lowered down the wellbore and into the interior of said screen. A wash fluid is then flowed fluid down the washstring and out through said screen into said mass of gravel surrounding the screen to fluidize, loosen, and remove said gravel. Once the mass of gravel has been loosen, the screen can then lifted upward out of said wellbore by applying a normal upward force the workstring which suspends the screen within the well.
