Bubble Maps

Figure-1

Bubble Map is a very common and conventional tool used by Reservoir Engineers to visually represent amount of fluids extracted by the wells of a reservoir.

Figure-2

Figure-3

The amount of fluids produced is represented as a circle with the center located at the well location and a radius corresponding to the fluids produced from the well. A number of different parameters and combinations are plotted in a bubble map for different kinds of interpretations. Some common combinations are:

• Cumulative Oil (Figure-1)
• Cumulative Liquid
• Cumulative/Current Oil and Water (as Pie Chart to show the proportions of oil and water, Figure-2)
• Estimated Ultimate Recovery and Cumulative Oil (as co-centric circles to show the amount of oil produced out of the EUR, Figure-3)
