Data Density Integrated from Gamma Ray, Memory (GRIM)

This is a well log used in the oil and gas industry. You could have found the code GRIM in your log evaluation software or your corporate datastores. The official name for this log is 'Data Density Integrated from Gamma Ray, Memory'. Usage of this log is not high and encountering it is a rare occasion.

The values of this log represent the density of data samples per length of borehole traversed, for a gamma ray logging measurement. In general this log therefore displays units of the mwd data density. Better said, the density of data samples per length of borehole traversed; may be expressed as samples per unit length or as a Boolean indicator of sample presence within a depth frame.

So basically this is a measure of the density (mass per unit volume) of a material. Usually at Standard conditions (STP). Also used to indicate the frequency of occurrence.

This log usually has the unit 'Counts Per Length'.

Note: This log is kept in the memory of the tool until it is recovered from the well.

Data from this log can be used to investigate the data density of the acquisition process. Similar logs are listed below:
