Injection

Analytical models can be used to simulate injection. To history match data from a well that has production as well as injection, load (see Importing Well Data) both the production and injection data into the Production Editor.

Both production and injection data will be honoured by the analytical model. If a certain time period has both production and injection data, Harmony will calculate the difference between the produced and injected volumes, and this calculated net production will be used for modeling.

Running forecasts or test designs is similar for injection and production wells, but for injection wells:

• the Allow Injection checkbox must be selected.

• injection rates are denoted using negative values.

Note:   Since wellhead forecasting is not yet available for injection, if Wellhead is selected from the Forecast Flowing Pressure drop-down list, the Allow Injection checkbox is grayed-out.
