Abstract

A method can include providing borehole data organized with respect to a cylindrical surface, defining one or more bedding planes based at least in part on the borehole data, and transforming at least a portion of the borehole data to a planar slab format for a plane interior to the cylindrical surface. Various other apparatuses, systems, methods, etc., are also disclosed.

Claims

1. A method comprising:

providing borehole data organized with respect to a cylindrical surface;

defining one or more bedding planes based at least in part on the borehole data; and

transforming at least a portion of the borehole data to a planar slab format for a plane interior to the cylindrical surface.

2. The method of claim 1 wherein the transforming comprises projecting data from the cylindrical surface to the plane.

3. The method of claim 1 wherein the transforming comprises projecting data from the cylindrical surface to the plane for regions between adjacent bedding planes.

4. The method of claim 2 wherein the projecting comprises projecting data from the cylindrical surface to the plane for multiple azimuthal directions.

5. The method of claim 1 wherein the transforming comprises representing defined bedding planes onto a 2-D surface.

6. The method of claim 1 comprising applying corrections to reduce effects on data quality during projection.

7. The method of claim 1 wherein the borehole data comprises resistivity data, or any other petrophysical measurement.

8. The method of claim 1 wherein the cylindrical surface corresponds to a cylindrical surface of the borehole.

9. The method of claim 1 comprising comparing the transformed data in the planar slab format to a cross-section of a solid core sample.

10. The method of claim 1 wherein the borehole data organized with respect to a cylindrical surface comprises image data.

12. The method of claim 1 wherein the transformed borehole data comprises image data.

13. The method of claim 1 wherein the borehole data organized with respect to a cylindrical surface comprises pixel values or petrophysical values.

14. One or more computer-readable storage media comprising computer-executable instructions to instruct a computing system to:

receive borehole data organized with respect to a cylindrical surface;

define one or more bedding planes based at least in part on the borehole data; and

transform at least a portion of the borehole data to a planar slab format for a plane interior to the cylindrical surface.

15. The one or more computer-readable storage media of claim 14 comprising computer-executable instructions to instruct a computing system to render the transformed borehole data to a display.

16. The one or more computer-readable storage media of claim 15 comprising computer-executable instructions to instruct a computing system to analyze the rendered transformed borehole data.

17. The one or more computer-readable storage media of claim 15 comprising computer-executable instructions to instruct a computing system to select a direction for the plane interior to the cylindrical surface.

18. A system comprising:

an interface to receive borehole data organized with respect to a cylindrical surface;

a graphical user interface to align a sinusoidal graphic with respect to an image of the borehole data;

circuitry to project at least a portion of the borehole data to a plane interior to the cylindrical surface; and

circuitry to render a 2-D image of the plane wherein the 2-D image comprises bedding planes derived from alignment of the sinusoidal graphic and projected borehole data.

19. The system of claim 18 comprising circuitry to analyze the 2-D image.

20. The system of claim 19 comprising an interface to transmit information derived from analysis of the 2-D image.
