Enter the total gas volume (BBLs, gallons) and the total liquid volume (BBLs, gallons) into the Foam Quality Calculator. The calculator will evaluate the Foam Quality. 

Foam Quality Formula

The following two example problems outline the steps and information needed to calculate the Foam Quality.

FQ = GV / (GV+LV) * 100


  • FQ is the Foam Quality (%)
  • GV is the total gas volume (BBLs, gallons) 
  • LV is the total liquid volume (BBLs, gallons) 

How to Calculate Foam Quality?

The following steps outline how to calculate the Foam Quality.

  1. First, determine the total gas volume (BBLs, gallons). 
  2. Next, determine the total liquid volume (BBLs, gallons). 
  3. Next, gather the formula from above = FQ = GV / (GV+LV) * 100.
  4. Finally, calculate the Foam Quality.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total gas volume (BBLs, gallons) = 30

total liquid volume (BBLs, gallons) = 20

FQ = GV / (GV+LV) * 100 = ?
