Resettable Ball Seat For Hydraulically Actuating Tools
US Patent:
2014026, Sep 18, 2014
Filed:
Feb 14, 2014
Appl. No.:
14/180618
Inventors:
- Houston TX, US
Candido Castro - Houston TX, US
Candido Castro - Houston TX, US
Assignee:
Weatherford/Lamb, Inc. - Houston TX
International Classification:
E21B 33/12
US Classification:
166374, 166193
Abstract:
A downhole tool has a housing, mandrel, and ball seat. The housing defines a first bore, and the mandrel defines a second bore. The mandrel is disposed in the first bore of the housing and defines an annular space with the housing. The ball seat is rotatably disposed in the second bore of the mandrel and defines an interior passage with a seat profile. First and second pistons are disposed in the annular space on opposing sides of the ball seat. These first and second pistons are movable along an axis of the tool in the annular space in opposing directions and are adapted to rotate the ball seat. Additionally, first and second biasing members are disposed in the annular space and bias the first and second pistons toward one another to reset the ball seat in the absence of pressure.
Expandable Ball Seat For Hydraulically Actuating Tools
US Patent:
2014025, Sep 11, 2014
Filed:
Mar 11, 2013
Appl. No.:
13/793688
Inventors:
Candido Castro - Houston TX, US
International Classification:
E21B 34/14
US Classification:
166318, 166316
Abstract:
A downhole tool has a housing, a mandrel, a seat, and a piston. The housing defines a first bore, and the mandrel is movably disposed in the first bore and defines a second bore. The mandrel has first and second mandrel sections or upper and lower cones, and the first mandrel section defines a cross-port communicating the second bore with an annular space between the mandrel and the housing. The seat is disposed in the first bore of the housing between the first and second mandrel sections. The seat is movable to a constricted state in the first bore to catch a dropped ball and is movable to an expanded state in the first bore to pass a dropped ball. The piston is disposed in the annular space and at least temporality supports the seat in its constricted state.
