Abstract

A seat apparatus comprises a housing defining at least a first flow path and at least a second flow path, a first seat disposed in the housing for receipt of a first object operative to obstruct the first flow path, and a second seat disposed in the housing for receipt of a second object operative to obstruct the second flow path and method.

Claims

exact text as granted — not AI-modified
1 . A seat apparatus comprising:
 a housing defining at least a first flow path and at least a second flow path;   a first seat disposed in the housing for receipt of a first object operative to obstruct the first flow path; and   a second seat disposed in the housing for receipt of a second object operative to obstruct the second flow path.   
     
     
         2 . The seat apparatus as claimed in  claim 1  wherein the housing includes a first concave portion operative to guide the first object towards the first seat. 
     
     
         3 . The seat apparatus as claimed in  claim 1  wherein the housing includes a second concave portion operative to guide the second object towards the second seat. 
     
     
         4 . The seat apparatus as claimed in  claim 1  wherein the first seat and the second seat are coplanar. 
     
     
         5 . The seat apparatus as claimed in  claim 1  wherein the first seat is disposed on a first plane and the second seat is disposed on a second plane. 
     
     
         6 . The seat apparatus as claimed in  claim 1  wherein the first object is spherically shaped. 
     
     
         7 . The seat apparatus as claimed in  claim 1  wherein the first flow path defined by the housing is tubular. 
     
     
         8 . The seat apparatus as claimed in  claim 2  wherein the concave portion is parabolicly shaped. 
     
     
         9 . The seat apparatus as claimed in  claim 2  wherein the concave portion is conically shaped. 
     
     
         10 . A seat apparatus comprising:
 a housing defining at least a first flow path, the axis of the first flow path coincident with a longitudinal axis of the housing;   at least a second flow path partially defined by the housing;   a first seat disposed in the housing for receipt of a first object operative to obstruct the first flow path; and   a second seat disposed in the housing for receipt of a second object operative to obstruct the second flow path.   
     
     
         11 . The seat apparatus as claimed in  claim 10  wherein the housing includes a first concave portion operative to guide the first object towards the first seat. 
     
     
         12 . The seat apparatus as claimed in  claim 10  wherein the housing includes a second concave portion operative to guide the second object towards the second seat. 
     
     
         13 . The seat apparatus as claimed in  claim 10  wherein the first seat and the second seat are coplanar. 
     
     
         14 . The seat apparatus as claimed in  claim 10  wherein the first seat is disposed on a first plane and the second seat is disposed on a second plane. 
     
     
         15 . The seat apparatus as claimed in  claim 10  wherein the first object is spherically shaped. 
     
     
         16 . The seat apparatus as claimed in  claim 10  wherein the first flow path defined by the housing is tubular. 
     
     
         17 . The seat apparatus as claimed in  claim 11  wherein the concave portion is parabolicly shaped. 
     
     
         18 . The seat apparatus as claimed in  claim 11  wherein the concave portion is conically shaped. 
     
     
         19 . A method for facilitating a pressure based operation in a downhole environment comprising:
 disposing a first object in a first seat in a housing, the first object operative to engage the first seat and to obstruct a first flow path partially defined by the housing; and   disposing a second object in a second seat in the housing, the second object operative to engage the second seat and obstruct a second flow path partially defined by the housing.   
     
     
         20 . The method of  claim 19 , wherein the method further comprises applying a hydraulic pressure to the housing, the hydraulic pressure operative to actuate the downhole device.
