Abstract

A method for processing a well data log may comprise adding one or more boundary areas to the well data log, dividing the well data log into one or more segments using the one or more boundary areas, processing each of the one or more segments on one or more information handling systems, and reforming each of the one or more segments into a final simulation. A system for processing a well data log may comprise one or more information handling systems in a cluster. The one or more information handling systems may be configured to perform the method for processing the well data log.

Claims (37)

1. A method for processing a well data log comprising:

measuring a formation with one or more sensors in a drilling or a logging operation to produce data;

populating the data onto the well data log;

parallelizing processing of each of two or more segments of the well data log comprising:

building one or more boundary areas into the well data log to form an overlapping band;

simulating at least part of the data within the overlapping band with a simulation algorithm to form simulated band data;

dividing the well data log into the two or more segments of the well data log and the overlapping band with the one or more boundary areas, wherein at least two segments from the two or more segments of the well data log comprise the same simulated band data from at least part of the overlapping band; and

simulating data from each of the two or more segments of the well data log with a neural network, wherein the neural network uses the simulated band data on one or more information handling systems; and

reforming each of the two or more segments of the well data log into a final simulation.

2. The method of claim 1 , wherein the one or more boundary areas are defined by a variogram parameter.

3. The method of claim 2 , wherein the variogram parameter is bound by a distance in which two chosen locations within the distance have correlation.

4. The method of claim 3 , wherein the one or more boundary areas includes data from the well data log.

5. The method of claim 1 , wherein the one or more boundary areas are based at least on a cluster size.

6. The method of claim 1 , wherein the simulation algorithm is a Sequential Gaussian Simulation (SGS) or a Sequential Indicator Simulation (SIS).

7. The method of claim 1 , wherein the two or more segments of the well data log are formed based at least on a number of information handling systems in a cluster available for processing.

8. The method of claim 7 , wherein each of the information handling systems are a node in the cluster.

9. The method of claim 8 , wherein each of the two or more segments of the well data log reduce computational time of the well data log.

10. The method of claim 1 , wherein the final simulation forms at least one model that is configured to estimate how much oil is in a volume and a standard error for the at least one model.

11. A system for processing a well data log comprising:

one or more sensors to measure a formation in a drilling or a logging operation to produce data;

one or more information handling systems in a cluster configured to:

populate the data onto the well data log;

parallelize process of each of two or more segments of the well data log comprising:

build one or more boundary areas into the well data log to form an overlapping band;

simulate at least part of the data within the overlapping band with a simulation algorithm to form simulated band data;

divide the well data log into two or more segments of the well data log and the overlapping band with the one or more boundary areas, wherein at least two segments from the two or more segments of the well data log comprise the same simulated band data from at least part of the overlapping band; and

simulate data from each of the two or more segments of the well data log with a neural network, wherein the neural network uses the simulated band data on the one or more information handling systems; and

reform each of the two or more segments of the well data log into a final simulation.

12. The system of claim 11 , wherein the one or more boundary areas are defined by a variogram parameter.

13. The system of claim 12 , wherein the variogram parameter is bound by a distance in which two chosen locations within the distance have correlation.

14. The system of claim 13 , wherein the one or more boundary area includes data from the well data log.

15. The system of claim 11 , wherein the one or more boundary area is based at least on a cluster size.

16. The system of claim 11 , wherein the simulation algorithm is a Sequential Gaussian Simulation (SGS) or Sequential Indicator Simulation (SIS).

17. The system of claim 11 , wherein the two or more segments of the well data log are formed based at least on a number of information handling systems in the cluster available for processing.

18. The system of claim 17 , wherein each of the information handling systems are a node in the cluster.

19. The system of claim 18 , wherein each of the two or more segments of the well data log reduce computational time of the well data log.

20. The system of claim 11 , wherein the final simulation forms at least one model that is configured to estimate how much oil is in a volume and a standard error for the at least one model.
