Abstract

A manifold trailer and pairing system are disclosed. The pairing system has a non-transitory computer readable medium storing processor executable code. The processor executable code causes a processor to receive identification data indicative of a first low pressure valve and a second low pressure valve connected to a low pressure manifold of a manifold trailer; receive identification data indicative of a first high pressure valve and a second high pressure valve connected to a high pressure manifold of the manifold trailer; and receive identification data indicative of a plurality of pumps. The processor determines a first association indicative of a first fluid connection between the first low pressure valve and a selected pump and a second association indicative of a second fluid connection between the selected pump and a selected high pressure valve. The processor populates the non-transitory computer readable medium with information indicative of the first and second associations.

First claim

What is claimed is:

1. One or more non-transitory computer readable medium storing processor executable code that when executed by one or more processor cause the one or more processor to:
receive identification data indicative of a first low pressure valve and a second low pressure valve, the first and second low pressure valves connected to a low pressure manifold of a manifold trailer;
receive identification data indicative of a first high pressure valve at a first high pressure station and a second high pressure valve at a second high pressure station, the first and second high pressure valves connected to a high pressure manifold of the manifold trailer;
receive identification data indicative of a plurality of pumps;
determine a first association indicative of a first fluid connection between the first low pressure valve and a selected pump of the plurality of pumps and a second association indicative of a second fluid connection between the selected pump and a selected high pressure valve selected from the first and second high pressure valves; and
populate a non-transitory computer readable medium with information indicative of the first association and the second association,
wherein the non-transitory computer readable medium is populated by the processor executable code causing the one or more processor to:
pressurize the low pressure manifold;
open a selected low pressure valve of the first and second low pressure valves;
detect a pressure increase on a pump, via a first pressure sensor;
close the selected low pressure valve retaining pressure between the selected low pressure valve and the pump;
associate the selected low pressure valve with the pump and store information indicative of the first association in the non-transitory computer readable medium;
selectively open and close, individually, the first and second high pressure valves;
detect a pressure decrease on the pump via a second pressure sensor for a selected high pressure valve of the first and second high pressure valves; and
associate the selected high pressure valve with the pump and store information indicative of the second association in the non-transitory computer readable medium.

2. The one or more non-transitory computer readable medium of claim 1 , further comprising associating the second low pressure valve with a second pump and a second high pressure valve.

3. The one or more non-transitory computer readable medium of claim 1 , wherein the processor executable code further causes the processor to close the first low pressure valve, the second low pressure valve, the first high pressure valve, and the second high pressure valve, the first and second low pressure valves connected to the low pressure manifold, the first high pressure valve at the first high pressure station and the second high pressure valve connected to the high pressure manifold, the low pressure manifold and the high pressure manifold being in fluid communication with the pump of the plurality of pumps.

4. The one or more non-transitory computer readable medium of claim 1 , wherein the processor executable code causes a blender to pressurize the low pressure manifold without initiating the plurality of pumps.

5. The one or more non-transitory computer readable medium of claim 1 , wherein the processor executable code further causes the one or more processor to associate the first low pressure valve with the pump and the selected high pressure valve.

6. A method, comprising:
pressurizing a low pressure manifold of a manifold trailer, the low pressure manifold having a first low pressure valve and a second low pressure valve;
opening a selected low pressure valve of the first and second low pressure valves;
detecting a pressure increase on a selected pump, via a first pressure sensor, indicative of a fluid communication between the selected low pressure valve and the selected pump;
closing the selected low pressure valve to retain pressure between the selected low pressure valve and the selected pump;
associating the selected low pressure valve with the selected pump and storing information indicative of the association of the selected low pressure valve and the selected pump in a non-transitory computer readable medium;
selectively opening and closing, individually, a first high pressure valve at a first high pressure station and a second high pressure valve at a second high pressure station, the first and second high pressure valves in fluid communication with a high pressure manifold on the manifold trailer;
detecting a pressure decrease on the selected pump via a second pressure sensor indicative of a fluid communication between a selected high pressure valve of the first and second high pressure valves and the selected pump; and
associating the selected high pressure valve with the selected pump and storing information indicative of the association of the selected high pressure valve and the selected pump in the non-transitory computer readable medium.

7. The method of claim 6 , further comprising associating the second low pressure valve with a second selected pump and a second selected high pressure valve.

8. The method of claim 6 , further comprising initially closing the first low pressure valve, the second low pressure valve, the first high pressure valve at the first high pressure station, and the second high pressure valve at the second high pressure station.

9. The method of claim 6 , wherein the low pressure manifold is pressurized by a blender without initiating the selected pump.

10. The method of claim 6 , further comprising associating the first low pressure valve with the selected pump and the selected high pressure valve.

11. A manifold trailer, comprising:
a low pressure manifold having a first low pressure valve and a second low pressure valve;
a high pressure manifold having a first high pressure valve at a first high pressure station and a second high pressure valve at a second high pressure station;
a plurality of actuators, wherein a first actuator of the plurality of actuators is connected to the first low pressure valve, a second actuator of the plurality of actuators is connected to the second low pressure valve, a third actuator of the plurality of actuators is connected to the first high pressure valve, and a fourth actuator of the plurality of actuators is connected to the second high pressure valve; and
a computer system having a processor and processor executable code which causes the processor to transmit signals to the first, second, third, and fourth actuators to selectively open and close the first and second low pressure valves and the first and second high pressure valves,
wherein the processor executable code further causes the processor to:
pressurize the low pressure manifold;
open a selected low pressure valve of the first and second low pressure valves;
detect a pressure increase on a first pump of a plurality of pumps, via a first pressure sensor, corresponding to the opening of the selected low pressure valve and close the selected low pressure valve retaining pressure between the selected low pressure valve and the first pump;
associate the selected low pressure valve with the first pump within one or more non-transitory computer readable medium and store information indicative of the association of the selected low pressure valve and the first pump in the non-transitory computer readable medium;
selectively open and close, individually, the first high pressure valve at the first high pressure station and second high pressure valve at the second high pressure station;
detect a pressure decrease on the first pump via a second pressure sensor corresponding to the openin
