Link / unlink analyses

By linking analyses you can combine multiple analyses in order to enforce consistency or generate calculated results. For example, you can link a Ratio Trend with a Decline analysis to calculate a rate forecast. Only Harmony Forecast analysis types can be linked, but the analyses must be of different types. When analyses are linked, they are displayed in the Analysis Manager under a single analysis name.

When analyses are linked, some analysis types permanently overwrite the results obtained by the other analysis. A summary of the order of precedence is listed below:

Parameter Order of analysis type precedence
Original Oil in Place (OOIP) /
Original Gas in Place (OGIP)

1. Material Balance

2. Volumetrics

EUR (Expected Ultimate Recovery)

1. Decline

2. Water-Oil Ratio

3. Material Balance

4. Volumetrics

Unlinking analyses does not restore the results of that analysis. For example, unlinking a Volumetrics analysis from a Material Balance analysis does not revert the OGIP of the Volumetrics analysis.
