Not certain if this is contributing to what you are seeing or not, but it is definitely not correct.

1. `'true'` is not the boolean value `True`.
2. You're using both `returnSize` and `intervalMinutes`, yes there are 96 - 15min intervals in 24 hours, but you only need to use one of these. Personally I think intervalMinutes is more readable
3. Your `columnName` list has to be a 1-1 match with the tagPaths, since `'Timestamp'` isn't one of the tagPaths that you are providing then it shouldn't be included in the list.

Your definition of the columnName list should look like:

```python
columnName = ['Well 4A m3','Well 9 m3','Well 12 m3','Well 15 m3','Well 17 m3']

```

Your call to `system.tag.queryTagHistory()` should look like:

```python
dataSet = system.tag.queryTagHistory(paths=TagPaths, startDate=startTime, endDate=endTime, aggregationMode=LastValue, returnFormat='Wide', ignoreBadQuality = True, columnNames=columnName, intervalMinutes =15 ) 

```

As an aside, if you want to print a dataset and see the contents, then you can use this helper script provided by @JordanCClark . It is quite handy.
