Can you please help understand TOTAL_INJ and TOTAL_PROD variables?

My understanding was that those values are total injected steam and total oil produced from the beginning of reservoir history, but looking at the dataset it must be something else.

  • Rows with same SURV_DTE may have different values of TOTAL_PROD.
  • TOTAL_PROD do not increase with the progress of time.


If you filter the data out to a specific CMPL_FAC_ID you will get the monotonic plot you are thinking of.


As mentioned above, your question gets at one of the fundamental ways to look at these data. These two variables should be viewed on a per well (CMPL_FAC_ID), per individual flow unit (SAND). In this view, TOTAL_INJ and TOTAL_PROD do increase through time.
