Abstract
A frac zipper manifold bridge connector comprises two bridge spools for connecting a well configuration unit of a frac zipper manifold to a frac tree of a wellhead. The connector comprises multiple connections involving threaded flanges, such that the orientation of the bridge spools may be adjusted to ensure that they are correctly aligned with the frac tree.
Claims12
A bridge connector for a frac zipper manifold, comprising:
- a bridge connector header comprising an axial throughbore and a separate input in fluid communication with the throughbore;
- first and second connection blocks in fluid communication with the axial throughbore of the bridge connector header;
- and
- first and second bridge spools attached to, and in fluid communication with, the first and second connection blocks respectively.
A method for installing a bridge connector for a frac zipper manifold, comprising the following steps:
- providing a frac zipper manifold comprising:
- a spool configured to allow axial flow of fracturing fluid;
- and
- an outlet configured to selectively allow flow of fracturing fluid to the bridge connector;
- providing a bridge connector header comprising an axial throughbore and a separate input in fluid communication with the throughbore;
- configuring the bridge connector header such that the input is in fluid communication with the outlet of the frac zipper manifold;
- configuring first and second connection blocks such that they are in fluid communication with the axial throughbore of the bridge connector header;
- and
- attaching first and second bridge spools to the first and second connection blocks respectively.
The method of claim 9, wherein the bridge connector header is rotated around a central axis of the first spool.
