Monthly Drilling Report

This report lists:
"Operating Days" are the number of days each rig was reported as operating per member monthly reports.
"Utilization" is expressed as a percentage calculated by dividing the actual number of Operating Days by the total number of Rig Days (days in the month x total fleet) multiplied by 100.

For monthly reports prior to 2019, utilization is an expression of "rigs listed as drilling/total registered fleet."
