In Productioneer you can keep track of your Oil and Water volumes in your tanks and tank batteries in the following ways:

1. Simple Volumes: You can enter daily volumes in BBL
2. Simple Ratios: You can set a simple Inch-to-Barrel ratio for a tank and Productioneer will calculate the volumes based on the tank gauging in Feet & Inches or preset increments (e.g. quarter inch increments)
3. Tank Tables: You can assign Tank Tables to your tanks and Productioneer will calculate the volumes based on the formulas in the table.
