Abstract

According to one aspect, a manifold assembly includes a skid, a low pressure manifold connected to the skid, and a high pressure manifold connected to the skid. In another aspect, the high pressure manifold has a modular configuration so that the high pressure manifold is disconnectable in whole or in part from the skid, and reconnectable in whole or in part to the skid. In yet another aspect, the high pressure manifold includes high pressure modules, all of which are in fluid communication with each other and each of which is adapted to be in fluid communication with at least one pump. In still yet another aspect, the low pressure manifold includes one or more flow lines, the high pressure manifold includes fittings, and the manifold assembly includes vibration isolators to dampen dynamic loading, the vibration isolators being disposed between the fittings and the one or more flow lines.

First claim

What is claimed is:

1. A module adapted to connect to a skid and form part of a manifold used to hydraulically fracture a subterranean formation within which a wellbore extends, the module comprising:
a first mounting bracket;
a first port connected to the first mounting bracket and adapted to be in fluid communication with a first pump, wherein the first pump is adapted to pressurize fluid to be conveyed to the wellbore to hydraulically fracture the subterranean formation within which the wellbore extends;
a second port connected to the first mounting bracket and adapted to be in fluid communication with a second pump that is different from the first pump, wherein the second pump is adapted to pressurize fluid to be conveyed to the wellbore to hydraulically fracture the subterranean formation within which the wellbore extends; and
a first fitting connected to the first mounting bracket and in fluid communication with at least one of the first and second ports;
wherein the module provides a vertical offset between the first fitting and:
the skid when the module is connected to the skid; and
a horizontal surface upon which the module is adapted to rest when the module is disconnected from the skid;

wherein the module is adapted to be connected to, and in fluid communication with, another module used to hydraulically fracture the subterranean formation within which the wellbore extends.

2. The module of claim 1 , wherein the first fitting is adapted to receive pressurized fluid from at least one of the first and second pumps and convey the pressurized fluid to the wellbore.

3. The module of claim 1 , further comprising a second fitting connected to the first mounting bracket and in fluid communication with the other of the first and second ports.

4. The module of claim 3 , wherein the first fitting is in fluid communication with the first port and is adapted to be in fluid communication with the first pump;
wherein the second fitting is in fluid communication with the second port and is adapted to be in fluid communication with the second pump; and
wherein the first and second fittings are adapted to receive pressurized fluid from the first and second pumps, respectively, and convey the pressurized fluid to the wellbore.

5. The module of claim 1 , further comprising a second mounting bracket connected to the first mounting bracket.

6. The module of claim 5 , further comprising at least one post extending from the second mounting bracket and adapted to engage:
the skid when the module is connected to the skid, the at least one post being disconnectable from, and reconnectable to, the skid; and
the horizontal surface when the module is disconnected from the skid;
wherein the post provides the vertical offset between the first fitting and either the skid or the horizontal surface, the vertical offset facilitating serviceability of the fitting.

7. The module of claim 5 , further comprising one or more vibration isolators connecting, and disposed between, the first and second mounting brackets.

8. The module of claim 1 , wherein the first mounting bracket defines first and second sides spaced in a parallel relation;
wherein the first fitting and the first and second ports are mounted on the first side of the first mounting bracket;
and
wherein the module further comprises:
at least one vibration isolator connected to the first mounting bracket on the second side thereof; and
a second mounting bracket connected to the at least one vibration isolator so that the vibration isolator is disposed between the first and second mounting brackets.

9. The module of claim 1 , further comprising:
first and second isolation valves mounted on the first mounting bracket and in fluid communication with the first and second ports, respectively;
wherein the first fitting is in fluid communication with at least the first isolation valve.

10. The module of claim 9 , further comprising a second fitting in fluid communication with the second isolation valve.

11. The module of claim 6 , wherein the at least one post permits the vertical offset to be adjustable with respect to at least one of: the skid; and the horizontal surface.

12. The module of claim 6 , wherein the module further comprises a carrier bracket adapted to support a swivel and connected to the at least one post.

13. The module of claim 7 , wherein, when the module is connected to the skid, the second mounting bracket is disposed above the skid, the one or more vibration isolators are disposed above the second mounting bracket, the first mounting bracket is disposed above the one or more vibration isolators, and the first fitting is disposed above the first mounting bracket.

14. The module of claim 7 , wherein at least one of the one or more vibration isolators comprises at least one of the following: a helical cable isolator; and a two-piece mount.

15. The module of claim 1 , further comprising:
a second mounting bracket connected to the first mounting bracket;
at least one post extending from the second mounting bracket and adapted to engage:
the skid when the module is connected to the skid, the at least one post being disconnectable from, and reconnectable to, the skid; and
the horizontal surface when the module is disconnected from the skid;

wherein the post provides the vertical offset between the first fitting and either the skid or the horizontal surface, the vertical offset facilitating serviceability of the fitting;
wherein the first mounting bracket defines first and second sides spaced in a parallel relation;
wherein the first fitting and the first and second ports are mounted on the first side of the first mounting bracket;
wherein one or more vibration isolators are connected to the first mounting bracket on the second side thereof so that the one or more vibration isolators connect, and are disposed between, the first and second mounting brackets; and
wherein, when the module is connected to the skid:
the second mounting bracket is disposed above the skid,
the one or more vibration isolators are disposed above the second mounting bracket,
the first mounting bracket is disposed above the one or more vibration isolators, and
the first fitting is disposed above the first mounting bracket.
