Logging curves can be reconstructed using the power law relation described by fractal theory. This method uses the local structure's nearby concurrent points to compensate for the average effect of logging probes and measurement errors. As an example, deep and medium induced conductivity (IMPH and IDPH) curves in ODP Leg 127 Hole 797C are reconstructed or corrected. The power spectra of corrected well-logging curves have more resolution components than the original ones. Thus, the fractal correction method makes well-logging more resolvable for thin beds.completedEconomic geology, geology of energy sourcesApplied geophysicscase studiescorrelationdata processingfractalsgeophysical surveysJapan SeaLeg 127North PacificNorthwest PacificOcean Drilling ProgramODP Site 797offshorePacific Oceanpetroleumpetroleum engineeringpetroleum explorationreservoir propertiesreservoir rockssurveyswell-loggingWest PacificYamato Basinurn:org.iodp:exp:127urnlargerWorkCitationcampaignurn:org.iodp:exp:127:site:797urnlargerWorkCitationstudyurn:org.iodp:exp:127urnlargerWorkCitationcampaignEnglishgeoscientificInformation134.3209134.321138.365538.3657
