Thank you for reaching out ot us.
First, you need to know RICs that can provide this information.
For example, I found that DST-STK-T-EIA represents "EIA STATISTICS US Total Distillate Fuel Oil Stocks Weekly Contract". Then, I can use this RIC with the Refinitiv Data Library for Python to retreive weekly historical data.
rd.get_history(universe="DST-STK-T-EIA",start="2019-01-01",end="2023-11-06", interval='1W')
The output is:
You can contact the Eikon or Refinitiv Workspace support team directly via MyRefinitiv to get those RICs.

You can use the Refinitiv Data Library for Python to retrieve the data.
There are examples available on GitHub.
