When you import wells, Harmony Enterprise checks for links to existing wells, so you can merge existing data, instead of creating new wells. Linking is done using the Entity Headers in the Attributes tab (excluding custom headers). Merging new data to existing wells is handled by your settings in the Options dialog box, Well Linking node.
The following identifiers are used based on the various import types.
| Import Format | Order of identifiers for linking |
|---|---|
| Database connection | Internal Harmony Well Key External Well Key API Number Sandface DLS Sandface NTS Entity Name Prod ID Entity No Entity Alias Name Propnum |
| Enerdeq, Dwights files, PowerTools |
API Number |
| Harmony file, .hldb file | Internal Harmony Well Key API Number Sandface DLS Sandface NTS Entity Name External Well Key Prod ID Entity No Entity Alias Name Propnum |
| IHDC | Sandface DLS Sandface NTS Prod ID |
| Merak and Lasser (.mer, .axp, .mxp, .vna, and .prn files) |
Sandface DLS Sandface NTS API Number |
| Piper Forecasts | Internal Harmony Well Key |
| Text (all text files excluding Dwights) | Well Identifier Sandface DLS Sandface NTS API Number Prod ID Entity Name Prod ID Entity Alias Name Entity No External Well Key Propnum |
| WellTest ) | Entity Name |
Note: All of the import formats are read-only except for text files and Harmony files. Applying changes in the Options dialog box applies changes globally.
If there are well-matching ambiguities, your input is required. In these cases, the Link Incoming Wells to Existing Wells dialog box opens.
