To use app, select either Exponential, Hyperbolic or Harmonic Decline model.

In the text field you can enter 3 of the 5 parameters. The other 2 will be calculated when Calc is pressed.

For example you can enter Decline, Initial Rate and Final Rate. Time and Cumulative will be calculated.

Press Metric or Barrels to swich between Units.

The decline models are applicable to both oil and gas wells. The relative decline rate and production rate decline equations for either Exponential, Armonic and Hyperbolic decline models, can be derived from volumetric reservoir model. Cumulative production expression is obtained by integrating the production rate decline equation.
