Abstract

In some embodiments, an apparatus and a system, as well as a method and an article, may operate to acquire live video stream information from an imaging device, the information including down hole cuttings image information, and then to process the down hole cuttings image information to determine data that quantifies at least one of a shape, a size distribution, or a volume of the down hole cuttings. Further activities include publishing changes in the data in conjunction with probable conditions associated with a borehole drilling operation or a borehole pumping operation. Additional apparatus, systems, and methods are disclosed.

Claims

1. A processor-implemented method, comprising:

acquiring live video stream information from an imaging device, the information including down hole cuttings image information;

processing the down hole cuttings image information to determine data that quantifies at least one of a shape, a size distribution, or a volume of the down hole cuttings; and

publishing changes in the data in conjunction with probable conditions associated with a borehole drilling operation or a borehole pumping operation.

2. The method of claim 1, wherein the acquiring further comprises:

acquiring the information from the imaging device having a field of view including a drilling mud screen.

3. The method of claim 1, wherein the processing comprises:

processing the information using a particle size analysis algorithm.

4. The method of claim 1, wherein the processing comprises:

processing the information using a three-dimensional facial recognition algorithm.

5. The method of claim 1, further comprising:

substantially continuously transmitting at least a portion of the data to a remote location.

6. The method of claim 5, wherein the transmitting further comprises:

transmitting at least a portion of the data to a real time log monitoring application program.

7. The method of claim 1, further comprising:

pumping fluid into a borehole to move the down hole cuttings into a field of view of the imaging device.

8. The method of claim 1, further comprising:

reducing a number of the wavelengths of light used to create the live video stream information, prior to the processing.

9. The method of claim 8, wherein the live video stream information includes drilling mud image information, and wherein the reducing further comprises:

reducing the number of the wavelengths of light to separate the drilling mud image information from the down hole cuttings image information.

10. The method of claim 1, wherein the processing comprises:

binning the data to provide the size distribution of the cuttings.

11. The method of claim 1, wherein publishing the changes comprises:

publishing trends in the data.

12. The method of claim 1, wherein the conditions comprise at least one of:

rate of penetration, formation pore pressure, weight on bit, drill pipe torque, or drilling angle.

13. The method of claim 1, further comprising:

indicating an efficiency of the borehole drilling operation or the borehole pumping operation as a sweeping operation, based on the data.

14. An apparatus, comprising:

an imaging device to acquire live video stream information including down hole cuttings image information; and

a processor to process the down hole cuttings image information to determine data that quantifies at least one of a shape, a size distribution, or a volume of the down hole cuttings, and to publish changes in the data in conjunction with probable conditions associated with a borehole drilling operation or a borehole pumping operation.

15. The apparatus of claim 14, further comprising:

at least one of a polarizer, a filter, or a beam splitter to intercept energy reflected or emitted by the down hole cuttings, and to reduce an amount of the energy received by the imaging device.

16. The apparatus of claim 14, wherein the imaging device comprises:

at least one of a visible light camera or an infrared camera.

17. A system, comprising:

a drilling mud screen to receive drilling mud; and

an image processing apparatus having a field of view including the drilling mud screen, the apparatus including an imaging device to acquire live video stream information including down hole cuttings image information, and a processor to process the down hole cuttings image information to determine data that quantifies at least one of a shape, a size distribution, or a volume of the down hole cuttings, and to publish changes in the data in conjunction with probable conditions associated with a borehole drilling operation or a borehole pumping operation.

18. The system of claim 17, wherein the drilling mud screen is included in a shaker deck.

19. The system of claim 17, further comprising:

a display to display the changes and the probable conditions.

20. The system of claim 17, further comprising:

a transmitter to transmit at least a portion of the data to a remote processor.
