Abstract
A method and a resistivity image logging tool connected or connectable to one or more processing devices process geological log data to construct missing information from destroyed or occluded parts using cues from observed data. The geological log data signals can be generated through use of the logging tool having one or more electrodes interacting with a formation intersected by a borehole. The processing involves the steps of: in respect of one or more data dimensions associated with missing values in a log data set, decomposing the signal into a plurality of morphological components; and morphologically reconstructing the signal such that missing values are estimated.
Claims23
A method of image processing implemented with one or more processing devices, the method comprising:
- obtaining, with the one or more processing devices, image information derived from geological log data signals generated through use of a logging tool having one or more electrodes interacting with a formation intersected by a borehole;
- constructing, with the one or more processing devices, missing image information missing from the obtained image information due to destroyed or occluded parts of the obtained image information by using cues from observed data comprising the steps of:
- in respect of one or more data dimensions associated with missing values in a log data set, decomposing the log data signal into a plurality of morphological components, and
- morphologically reconstructing the log data signal such that missing values are estimated;
- and
- producing, with the one or more processing devices, a resulting image incorporating the missing image information into the obtained image information.
