Abstract

A method for determining a screen break may include obtaining a fluid stream after a screening system in a drilling process; placing the fluid stream into a screen break detector; obtaining a pressure within a well of the screen break detector when the screening system is in a first state; obtaining a pressure within the well of the screen break detector when the screening system is in a second state; determining a differential pressure within the well of the screen break detector obtained when the screening system is in the second state compared to the pressure when the screen break is in the first state; and transmitting a notification to an operator when the pressure within the screen break detector obtained when the screening system is in the second state is greater than the pressure within the screen break detector when the screening system is in the first state.

First claim

What is claimed is:

1. A method, comprising:
receiving a fluid stream from a screen system of a fluid system into a screen break detector, wherein the screen system comprises at least one screen, the screen break sensor comprises a sample screen, and the fluid system comprises a hydrocarbon system coupled to a wellbore;
monitoring, via sensor data received by a processor, a fluid pressure of the fluid stream flowing through the sample screen of the screen break detector;
detecting, via analysis of the sensor data by the processor, a condition of the at least one screen of the screen system based on the fluid pressure and one or more pressure thresholds; outputting, via the processor, a notification of the condition of the at least one screen of the screen system; and
changing a fluid flow in the fluid system in response to detection of the condition of the at least one screen of the screen system.

2. The method of claim 1 , wherein changing the fluid flow comprises stopping the fluid flow, diverting the fluid flow, or a combination thereof, wherein the one or more pressure thresholds comprise a diversion threshold, a stopping threshold, or a combination thereof.

3. The method of claim 1 , wherein the screen system comprises a shaker having the at least one screen.

4. The method of claim 1 , wherein the hydrocarbon system comprises a drilling rig, and the fluid stream comprises a drilling fluid including drill cuttings or solid materials.

5. The method of claim 1 , wherein the condition comprises a degraded condition or a screen break of the at least one screen of the screen system.

6. The method of claim 1 , wherein the notification comprises a visual alarm or an audible alarm.

7. The method of claim 1 , further comprising determining a differential pressure between a first value of the fluid pressure when the screen system is operating in a first state and a second value of the fluid pressure when the screen system is operating in a second state.

8. The method of claim 7 , wherein the first state comprises a steady state of the fluid pressure over a first time frame, and the second state comprises an increase of the fluid pressure over a second time frame.

9. The method of claim 1 , wherein monitoring the fluid pressure comprises monitoring a change in the fluid pressure over a time frame.

10. The method of claim 1 , wherein the at least one screen has a first mesh size, the sample screen has a second mesh size, and the second mesh size is coarser than the first mesh size.

11. The method of claim 1 , wherein the screen break detector comprises a fluid chamber, the sample screen disposed in the fluid chamber, a pressure detector fluidly coupled to the fluid chamber, a fluid sample line fluidly coupled to the fluid chamber on a first side of the sample screen, and a fluid removal line fluidly coupled to the fluid chamber on an opposite second side of the sample screen.

12. A system, comprising:
a screen break detector, comprising:
a sample screen configured to receive a fluid stream from a screen system of a fluid system, wherein the screen system comprises at least one screen, and the fluid system comprises a hydrocarbon system coupled to a wellbore;
a pressure detector configured to monitor a fluid pressure of the fluid stream flowing through the sample screen;
a computing system having a processor and memory, wherein the computing system is configured to detect a condition of the at least one screen of the screen system based on the fluid pressure and one or more pressure thresholds; and
the computing system is configured to change a fluid flow in the fluid system in response to detection of the condition of the at least one screen of the screen system.

13. The system of claim 12 , wherein the computing system is configured to output a notification of the condition of the at least one screen of the screen system.

14. The system of claim 12 , wherein the condition comprises a degraded condition or a screen break of the at least one screen of the screen system.

15. The system of claim 12 , wherein the screen system further comprises a shaker with the at least one screen.

16. A system, comprising:
a computing system comprising one or more processors and a non-transitory computer-readable storage medium comprising instructions executable by the one or more processors to:
monitor a fluid pressure of a fluid stream flowing through a sample screen of a screen break detector, wherein the fluid stream is received from a screen system of a fluid system, the screen system comprises at least one screen, and the fluid system comprises a hydrocarbon system coupled to a wellbore;
detect a condition of the at least one screen of the screen system based on the fluid pressure and one or more pressure thresholds; and
change a fluid flow in the fluid system in response to detection of the condition of the at least one screen of the screen system.

17. The system of claim 16 , wherein the instructions are executable by the one or more processors to: output a notification of the condition of the at least one screen of the screen system.

18. The system of claim 16 , wherein the condition comprises a degraded condition or a screen break of the at least one screen of the screen system.
