Standardizing Recovery Descriptions

Our method for defining the ‘recovery description nomenclature’ provides a systematic approach to assigning gas/fluid descriptions, standardizing the process across the company/testers.  Utilizing the PORTAL system, gas/fluid descriptions are automatically generated based on recovery breakdowns (percentages) to create consistent results no matter the tester or the well.  The system creates various cuts of gas/fluid from ‘slightly cut’ to ‘heavy cut’ with the smallest percentage (product) listed first and the final and largest percentage simply listed as the gas/fluid described (G, O, W, M).  The PORTAL uses the following criteria when assigning the standardized recovery descriptions:

• Less than 1% show TRACE ( )

• 1% to 19% shows SL( )C  -  Slightly ____ Cut

• 20% to 29% shows ( )C  -  ______ Cut

• Greater than 30% shows H( )C  -  Heavy _____ Cut

        * (  ) indicates G for gas, O for oil, W for water, and M for mud

By using this method to generate the description(s) of the recovery, Diamond Testing provides a clear and repeatable process for our customers drill stem test recovery descriptions; allowing for consistent recovery descriptions for future comparative analysis.
