4 foot vertical resolution matched res. - DOI 60 inch (M4R6) |
This is a well log used in the oil and gas industry. The acronym M4R6 can be found in any (ASCII) log files provided by the logging company. 4 foot vertical resolution matched res. - DOI 60 inch is the offical name for this log. This log is not often acquired after (or during) drilling a well. This log displays readings of the array Resistivity measurement using laterolog (or guard log) resistivity logging principles. So basically this is a measure of the formation resistivity as measured by a device capable of taking measurements of at various combinations of resolution, depth of investigation and/or in different azimuthal directions.This log usually has the unit 'Resistivity'. This is the property of a material which resists the flow of electrical current. The ratio of electric-field intensity to current density. The reciprocal of conductivity. Data for this log is produced by a tool that uses a laterolog logging technique and can be used to investigate the resistivity of the formation. Similar logs are listed below:
