Abstract

A well log is obtained that includes log data gathered along a trajectory of a wellbore. An orientation parameter defining a perspective for displaying the log data along the trajectory is also obtained. Following a path of the trajectory, an image strip is rendered from the log data based on the orientation parameter, where the image strip is a pictorial representation of the log data. The image strip is displayed along the trajectory.

First claim

What is claimed is:

1. A method for displaying log data, comprising:
obtaining a well log comprising log data gathered along a trajectory of a wellbore;
obtaining an orientation parameter defining a perspective for displaying the log data, the perspective corresponding to a radial location on the wellbore;
rendering, following a path of the trajectory, an image strip from the log data based on the orientation parameter, wherein the image strip is a pictorial representation of the log data projected on the wellbore; and
displaying the image strip along the trajectory.

2. The method of claim 1 , wherein rendering the image strip comprises:
creating a geometry tube along the trajectory;
identifying a portion of the log data based on the orientation parameter;
generating a mapping between the portion of the log data identified and the geometry tube; and
creating the image strip along the trajectory, wherein creating the image strip comprises, for each of a plurality of points in the portion of the log data:
identifying a value of a point of the plurality of points in the portion of the log data,
identifying, according to the mapping, a position of the point in the image strip, and
relating the value to the position in the image strip.

3. The method of claim 2 , further comprising:
obtaining a radius parameter defining a width of the image strip,
wherein the geometry tube is sized based on the radius parameter.

4. The method of claim 2 , further comprising:
generating a log view of the well log, wherein the log view is a straight line display of the log data,
wherein the mapping is between the log view and the geometry tube.

5. The method of claim 1 , further comprising:
obtaining a color palette mapping the log data to a plurality of colors, wherein the image strip is rendered according to the color palette.

6. The method of claim 1 , further comprising:
detecting a plurality of formation layers; and
rendering the plurality of formation layers visually on top of the image strip to obtain a revised image,
wherein displaying the image strip along the trajectory comprises displaying the revised image.

7. The method of claim 1 , wherein the well log is an image log.

8. A system for displaying log data, comprising:
a data repository for storing a well log comprising log data gathered along a trajectory of a wellbore;
a computer processor; and
an analysis tool, executing on the computer processor, operatively connected to the data repository, and comprising:
a user interface configured to:
obtain an orientation parameter defining a perspective for displaying the log data, the perspective corresponding to a radial location on the wellbore, and
displaying an image strip along the trajectory, wherein the image strip is a pictorial representation of the log data projected on the wellbore, and
an image strip composer configured to:
render, along the trajectory, the image strip from the log data in the well log based on the orientation parameter.

9. The system of claim 8 , wherein rendering the image strip comprises:
creating a geometry tube over the trajectory;
identifying a portion of the log data based on the orientation parameter;
generating a mapping between the portion of the log data identified and the geometry tube; and
creating the image strip along the trajectory, wherein creating the image strip comprises, for each of a plurality of points in the log data:
identifying, using the mapping, a value of at least one point of the plurality of points in the log data, and
relating the value to the position in the image strip.

10. The system of claim 9 , wherein the user interface comprises a first input field for obtaining the orientation parameter.

11. The system of claim 10 , wherein the user interface comprises a second input field for obtaining a radius parameter defining a width of the image strip, and wherein the geometry tube is sized based on the radius parameter.

12. The system of claim 9 , wherein the analysis tool further comprises:
a log composer configured to generate a log view of the well log, wherein the log view is a straight line display of the log data,
wherein the mapping is between the log view and the geometry tube.

13. The system of claim 8 , wherein the user interface is further configured to:
obtain a color palette mapping the log data to a plurality of colors, wherein the image strip is rendered according to the color palette.

14. The system of claim 8 , wherein the analysis tool further comprises:
a layer composer configured to:
detect a plurality of formation layers; and
render the plurality of formation layers visually on top of the image strip to obtain a revised image,
wherein displaying the image strip along the trajectory comprises displaying the revised image.

15. A non-transitory computer readable medium comprising computer readable program code for displaying log data, the computer readable program code for:
obtaining a well log comprising log data gathered along a trajectory of a wellbore;
obtaining an orientation parameter defining a perspective for displaying the log data, the perspective corresponding to a radial location on the wellbore;
rendering, by a computer processor, along the trajectory, an image strip from the log data based on the orientation parameter, wherein the image strip is a pictorial representation of the log data projected on the wellbore; and
displaying, by the computer processor, the image strip along the trajectory.

16. The non-transitory computer readable medium of claim 15 , wherein rendering the image strip comprises:
creating a geometry tube over the trajectory;
identifying a portion of the log data based on the orientation parameter;
generating a mapping between the portion of the log data identified and the geometry tube; and
creating the image strip along the trajectory, wherein creating the image strip comprises, for each of a plurality of points in the log data:
identifying a value of a point of a plurality of points in the log data,
identifying, according to the mapping, a position of the point in the image strip, and
relating the value to the position in the image strip.

17. The non-transitory computer readable medium of claim 16 , further comprising computer readable program code for:
obtaining a radius parameter defining a width of the image strip,
wherein the geometry tube is sized based on the radius parameter.

18. The non-transitory computer readable medium of claim 16 , further comprising computer readable program code for:
generating a log view of the well log, wherein the log view is a straight line display of the log data,
wherein the mapping is between the log view and the image strip.

19. The non-transitory computer readable medium of claim 15 , further comprising computer readable program code for:
