Abstract

Method and system for improving the speed and accuracy of determining formation properties using multiple logging data are disclosed. Logging data relating to the formation of interest is obtained and used as an input. High frequency noise is then removed from the logging data and bed-boundary determination is performed using the logging data. An adaptive low pass filter is applied to the logging data and the logging data is inverted. The inverted logging data is then visually interpreted.

First claim

What is claimed is:

1. A method of multi-component induction (MCI) logging for a formation of interest comprising:
inputting logging data from an MCI logging tool relating to the formation of interest, wherein the logging data comprises triaxial measurements;
removing high frequency noise from the logging data;
performing bed-boundary determination using the logging data;
applying an adaptive low pass filter to the logging data,
inverting the logging data, wherein the inverting comprises performing a V1D inversion of the logging data; and
determining one or more formation properties based on the inverted logging data.

2. The method of claim 1 , wherein the adaptive low pass filter reduces horn effect of the logging data.

3. The method of claim 1 , wherein inputting logging data relating to the formation of interest comprises:
placing a logging tool in the formation of interest;
collecting data from the formation of interest using the logging tool; and
using the collected data as input logging data.

4. The method of claim 1 , wherein inputting logging data comprises obtaining the logging data from a plurality of logging tools.

5. The method of claim 4 , wherein the plurality of logging tools are selected from a group consisting of an MCI tool, a multi-arm caliper, an imager, and a dipmeter.

6. The method of claim 1 , wherein applying an adaptive low pass filter to the logging data comprises applying a Kaiser window.

7. The method of claim 1 , wherein inverting the logging data comprises:
performing an R1D inversion of the logging data; and
combining the R1D inversion of the logging data and the V1D inversion of the logging data.

8. The method of claim 1 , wherein visually interpreting the inverted logging data comprises generating one or more of an MCI combined log, a dual frequency log, a differential log and a derivative log.

9. The method of claim 1 , wherein the logging data reflects at least one of a horizontal resistivity of the formation of interest, a vertical resistivity of the formation of interest, a dip of the formation of interest and a strike of the formation of interest.

10. The method of claim 1 , further comprising determining one or more properties of the formation of interest, wherein the one or more properties are selected from a group consisting of horizontal resistivity, vertical resistivity, dip and strike of the formation.

11. A multi-component logging system comprising:
a memory;
a processor coupled to the memory, wherein the memory comprises one or more instructions that, when executed by the processor, cause the processor to:
receive logging data from an MCI logging tool comprising triaxial measurements relating to a formation of interest,
remove high frequency noise from the logging data;
perform bed-boundary determination using the logging data;
apply an adaptive low pass filter to the logging data,
invert the logging data using V1D inversion; and
determine one or more formation properties based on the inverted logging data.

12. The system of claim 11 , wherein the adaptive low pass filter reduces horn effect of the logging data.

13. The system of claim 11 , wherein receiving logging data relating to the formation of interest comprises:
placing a logging tool in the formation of interest;
collecting data from the formation of interest using the logging tool; and
using the collected data as input logging data.

14. The system of claim 11 , wherein receiving logging data comprises obtaining the logging data from a plurality of logging tools.

15. The system of claim 14 , wherein the plurality of logging tools are selected from a group consisting of an MCI tool, a multi-arm caliper, an imager, and a dipmeter.

16. The system of claim 11 , wherein applying an adaptive low pass filter to the logging data comprises applying a Kaiser window.

17. The system of claim 11 , wherein inverting the logging data comprises:
performing an R1D inversion of the logging data; and
combining the R1D inversion of the logging data and the V1D inversion of the logging data.

18. The system of claim 11 , wherein visually interpreting the inverted logging data comprises generating one or more of an MCI combined log, a dual frequency log, a differential log and a derivative log.

19. The system of claim 11 , wherein the logging data reflects at least one of a horizontal resistivity of the formation of interest, a vertical resistivity of the formation of interest, a dip of the formation of interest and a strike of the formation of interest.

20. The system of claim 11 , further comprising instructions to determine one or more properties of the formation of interest, wherein the one or more properties are selected from a group consisting of horizontal resistivity, vertical resistivity, dip and strike of the formation.
