Abstract
A computer-implemented method to perform joint inversion of formation data includes performing a first inversion of a formation surrounding a wellbore at a first frequency/spacing configuration, and performing a second inversion of the formation at a second frequency/spacing configuration that is different from the first configuration. The method also includes assigning a first fluctuating weight to the first inversion, and assigning a second fluctuating weight to the second inversion. The method further includes merging the first and second inversion based on a combination of the first and second fluctuating weights.
Claims20
A computer-implemented method to perform joint inversion of formation data, comprising:
- performing a first inversion of a first set of formation data indicative of a formation surrounding a wellbore, wherein the first set of formation data is obtained by a logging tool acquiring a first set of tool measurements;
- performing a second inversion of a second set of formation data indicative of the formation, wherein the second set of formation data is obtained by the logging tool acquiring a second set of tool measurements that is different from the first set;
- assigning a first fluctuating weight to the first inversion;
- assigning a second fluctuating weight to the second inversion;
- and
- merging the first inversion and the second inversion into a combined inversion, the combined inversion being a result of a merger of the first inversion and the second inversion.
A joint inversion system, comprising:
- storage medium;
- and
- one or more processors configured to:
- perform a first inversion of a first set of formation data indicative of a formation surrounding a wellbore, wherein the first set of formation data is obtained by a logging tool acquiring a first set of tool measurements;
- perform a second inversion of a second set of formation data indicative of the formation, wherein the second set of formation data is obtained by the logging tool acquiring a second set of tool measurements that is different from the first set;
- assign a first fluctuating weight to the first inversion;
- assign a second fluctuating weight to the second inversion;
- and
- merge the first inversion and the second inversion into a third combined inversion, the combined inversion being a result of a merger of the first inversion and the second inversion.
A non-transitory computer-readable medium comprising instructions, which when executed by one or more processors, cause the one or more processors to perform operations comprising:
- performing a first inversion of a first set of formation data indicative of a formation surrounding a wellbore, wherein the first set of formation data is obtained by a logging tool acquiring a first set of tool measurements;
- performing a second inversion of a second set of formation data indicative of the formation, wherein the second set of formation data is obtained by the logging tool acquiring a second set of tool measurements that is different from the first set;
- assigning a first fluctuating weight to the first inversion;
- assigning a second fluctuating weight to the second inversion;
- and
- merging the first inversion and the second inversion into a combined inversion, the combined inversion being a result of a merger of the first inversion and the second inversion.
