Frac manifold isolation tool

Abstract

A frac manifold isolation tool configured to connect to a zipper spool, and comprising a mandrel that is axially movable and a hydraulic setting tool configured to move the mandrel from an open position, in which fracturing fluid is allowed to flow from a zipper spool to a connected frac tree, to a closed position, in which the mandrel and its associated cup tool direct flow.

1 . A zipper manifold comprising two or more well configuration units, wherein one or more well configuration units comprises:
 a bridge connector header comprising a throughbore and a bore in fluid communication with the throughbore;   a first mandrel comprising a first end, a second end, and a generally tubular member with an outer surface and a throughbore;   a cup tool proximate to the second end of the first mandrel and adapted to sealingly engage, at a pack-off location, an inner portion of the well configuration unit located below the bore of the bridge connector header;   one or more first hydraulic setting cylinders configured to axially move the first mandrel through the throughbore to position the first mandrel and cup tool at the pack-off location.   
     
     
         2 . The zipper manifold of  claim 1 , wherein the cup tool comprises a first seal assembly configured to seal within the inner portion of the well configuration unit. 
     
     
         3 . The zipper manifold of  claim 2 , wherein the cup tool comprises a first piston configured to energize the first seal assembly. 
     
     
         4 . The zipper manifold of  claim 3 , wherein the cup tool comprises a first actuator configured to direct a fluid flow to the first piston. 
     
     
         5 . The zipper manifold of  claim 1 , wherein the cup tool comprises a first seal assembly and a second seal assembly, the seal assemblies configured to seal within the inner portion of the well configuration unit. 
     
     
         6 . The zipper manifold of  claim 5 , wherein the cup tool comprises a first piston configured to energize the first seal assembly and a second piston configured to energize the second seal assembly. 
     
     
         7 . The zipper manifold of  claim 6 , wherein the cup tool comprises a first actuator configured to direct a fluid flow to the first piston and a second actuator configured to direct the fluid flow to the second piston. 
     
     
         8 . The zipper manifold of  claim 3 , wherein the first piston is an internal beveled piston. 
     
     
         9 . The zipper manifold of  claim 3 , wherein the first piston is an external beveled piston.
