Array Induction Two Foot Resistivity A10 (AT10)

This is an acronym for a well log used in the oil and gas industry. You could find this abbreviation AT10 in your log evaluation software or any (ASCII) log files provided by the logging company. The abreviatin stands for 'Array Induction Two Foot Resistivity A10'. The business value of this log is often deamed high.

Use this log to investigate 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:
