Abstract

A hydraulic fracturing system for fracturing a subterranean formation including a pump in communication via pump components with a wellbore that intersects the formation, and that pressurizes fluid in the wellbore, the fluid comprising a fracturing fluid slurry. The system further includes hydraulic fracturing system components for making the fracturing fluid slurry, and a monitoring system that selectively captures and transmits real time images of at least one of the hydraulic fracturing system components or pump components to enable remote monitoring of the at least one of the hydraulic fracturing system components or pump components.

First claim

What is claimed is:

1. A hydraulic fracturing system for fracturing a subterranean formation comprising:
a pump in communication via pump components with a wellbore that intersects the formation, and that pressurizes fluid in the wellbore, the fluid comprising a fracturing fluid slurry;
hydraulic fracturing system components for making the fracturing fluid slurry; and
a monitoring system that selectively captures and transmits real time images of at least one of the hydraulic fracturing system components or pump components to enable remote monitoring of the at least one of the hydraulic fracturing system components or pump components;
wherein the monitoring system selectively captures and transmits real time images of an opening to a vessel, so that a level within the vessel is discernible in the images.

2. The hydraulic fracturing system of claim 1 , wherein the monitoring system comprises:
a camera;
a controller;
a display;
a human machine interface; and
communication means between the camera, controller, human machine interface, and the display.

3. The hydraulic fracturing system of claim 1 , wherein the display comprises a monitor from which the images are viewed.

4. The hydraulic fracturing system of claim 3 , wherein the display is disposed within a passenger compartment mounted to a fluid blender, so that the images can be viewed by operations personnel in the passenger compartment.

5. The hydraulic fracturing system of claim 1 , wherein the hydraulic fracturing components are selected from the group consisting of a chemical tanker, a hydration unit, a hopper, a blender unit, and auger associated with a blender unit, a conveyor, and an acid tanker.

6. The hydraulic fracturing system of claim 1 , wherein the pump components are selected from the group consisting of intake piping, discharge piping, hoses, fittings, and valves associated with a hydraulic fracturing pump.

7. The hydraulic fracturing system of claim 1 , wherein the monitoring system comprises a camera disposed on a trailer, and wherein the hydraulic fracturing components or pump components comprise hose or pipe connections on the trailer.

8. The hydraulic fracturing system of claim 1 , wherein the monitoring system comprises a camera disposed on a first trailer, and wherein the hydraulic fracturing components or pump components comprise hose or pipe connections on a second trailer that is adjacent the first trailer.

9. The hydraulic fracturing system of claim 1 , wherein the monitoring system selectively captures and transmits real time images of a silica exposure zone.

10. The hydraulic fracturing system of claim 1 , wherein the vessel contains proppant.

11. The hydraulic fracturing system of claim 1 , wherein the vessel contains acid.

12. The hydraulic fracturing system of claim 1 , wherein the vessel contains chemicals.

13. A method of fracturing a subterranean formation comprising:
driving a pump to pressurize fluid in a hydraulic fracturing system containing hydraulic fracturing components and pump components;
fracturing the formation by directing the pressurized fluid into a wellbore that intersects the formation; and
monitoring the hydraulic fracturing system with a monitoring system by:
obtaining images of hydraulic fracturing components and pump components of the hydraulic fracturing system; and
viewing the images remotely;
wherein the monitoring system selectively captures and transmits real time images of an opening to a vessel, so that a level within the vessel is discernible in the images.

14. The method of claim 13 , wherein the hydraulic fracturing components and pump components are disposed in areas where there is a greater possibility of personal injury than where the images are being viewed.

15. The method of claim 13 , wherein the step of obtaining images is performed by a camera that is disposed adjacent at least one of the hydraulic fracturing components or the pump components.

16. The method of claim 15 , wherein the step of viewing is performed within an enclosure.

17. The method of claim 13 , further comprising:
selectively obtaining images of different hydraulic fracturing components or pump components on a single monitor.

18. The method of claim 13 , wherein the hydraulic fracturing components and pump components comprise discharge piping that is in fluid communication with the pump, and vessel openings, and wherein the images if of the hydraulic fracturing system include images of at least one of a silica exposure zone, hose connections, a high pressure zone that includes discharge pumps or discharge pipes or both, a chemical exposure zone, high voltage zones, and natural gas supply piping.
