This is a log of measurements along a well bore (a well-log). The acronym
HMIN is a unique identifier to recognize this particular log and can be encountered in your log evaluation software or your corporate datastores. The abreviatin stands for
'HIP Micro Inverse Resistivity'. The usage of this log is well established. This log can be used to evaluate the micro Resistivity measurement using an "inverse" lateral electrode arrangement; traditionally combined with Micro Normal Resistivity in a Microlog survey for identifying permeable beds.
Concluding, this is a measure of the measurement of the resistivity of the formation within the first few inches of the borehole wall.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 inverse logging technique and can be used to investigate the resistivity of the formation. A similar log might be:
Synthetic Micro-Inverse Resistivity (SMIN).
