Abstract

Systems and methods for the construction of closed bodies from incomplete interpretations of geologic structures during geophysical modeling.

Claims

1. A method for constructing a closed body from an input data set during three-dimensional modeling comprising:

determining an orientation for each input point in the input data set wherein each input point comprises coordinates for a location and a direction in which light would reflect off of the location out of the closed body;

converting each input point and its respective orientation from a native coordinate system to a common coordinate system using a computer processor; and

constructing the closed body using each input point and its respective orientation within the common coordinate system.

2. The method of claim 1, wherein each input point comprises (x,y,z) and (nx,ny,nz) coordinates, the (x,y,z) coordinates represents the location of each respective input point on a continuous geologic body and the (nz,ny,nz) coordinates represents the direction in which light would reflect off of the location of each respective input point.

3. The method of claim 2, wherein the (nz,ny,nz) coordinates represents a normal.

4. The method of claim 3, wherein the orientation for each input point in the input data set is determined by calculating the normal and orienting the normal to point out of the closed body.

5. The method of claim 3, wherein the orientation for each input point in the input data set is determined by estimating the normal and orienting the normal to point out of the closed body.

6. The method of claim 3, wherein the normal for each respective input point is predetermined and oriented to point out of the closed body.

7. The method of claim 1, wherein the input data set comprises multiple horizons.

8. The method of claim 7, wherein at least one of the multiple horizons includes a native coordinate system that is the same as a common coordinate system for the multiple horizons.

9. The method of claim 1, wherein the closed body is constructed by reducing a total number of input points in the input data set.

10. The method of claim 9, wherein the closed body is constructed by performing a Poisson reconstruction.

11. A non-transitory program carrier device tangibly carrying computer executable instructions for constructing a closed body from an input data set during three-dimensional modeling, the instructions being executable to implement:

determining an orientation for each input point in the input data set wherein each input point comprises coordinates for a location and a direction in which light would reflect off of the location out of the closed body;

converting each input point and its respective orientation from a native coordinate system to a common coordinate system; and

constructing the closed body using each input point and its respective orientation within the common coordinate system.

12. The method of claim 11, wherein each input point comprises (x,y,z) and (nx,ny,nz) coordinates, the (x,y,z) coordinates represents the location of each respective input point on a continuous geologic body and the (nz,ny,nz) coordinates represents the direction in which light would reflect off of the location of each respective input point.

13. The method of claim 12, wherein the (nz,ny,nz) coordinates represents a normal.

14. The method of claim 13, wherein the orientation for each input point in the input data set is determined by calculating the normal and orienting the normal to point out of the closed body.

15. The method of claim 13, wherein the orientation for each input point in the input data set is determined by estimating the normal and orienting the normal to point out of the closed body.

16. The method of claim 13, wherein the normal for each respective input point is predetermined and oriented to point out of the closed body.

17. The method of claim 11, wherein the input data set comprises multiple horizons.

18. The method of claim 17, wherein at least one of the multiple horizons includes a native coordinate system that is the same as a common coordinate system for the multiple horizons.

19. The method of claim 11, wherein the closed body is constructed by reducing a total number of input points in the input data set.

20. The method of claim 19, wherein the closed body is constructed by performing a Poisson reconstruction.
