Abstract
Measurements made by a wireline-conveyed pulsed neutron tool with two or more gamma ray detectors are used to provide a mineralogical and/or elemental image of the formation. This may be used in reservoir navigation and in furthering the understanding of the geology of the prospect.
Claims22
An apparatus configured to estimate an elemental composition of an earth formation, the apparatus comprising:
- a radiation detector configured to be conveyed on a wireline into a borehole;
- and
- at least one processor configured to:
- associate an azimuth with each of a plurality of measurements made by the radiation detector;
- and
- process the plurality of measurements and estimate an elemental composition of the earth formation for the plurality of azimuths.
A method of estimating an elemental composition of an earth formation, the method comprising:
- using a wireline for conveying a radiation detector into a borehole;
- associating an azimuth with each of a plurality of measurements made by the radiation detector and
- estimating, from the measurements, an elemental composition of the earth formation for each of the plurality of azimuths.
A computer readable medium accessible to at least one processor, the computer-readable medium comprising instructions that enable the at least one processor to:
- associate an azimuth with each of a plurality of measurements made by a radiation detector conveyed on a wireline in a borehole in an earth formation;
- and
- estimate an elemental composition of the earth formation for each of the plurality of azimuths.
