      Drilling Activity - Advanced Core Recovery Calculator

      Advanced Core Recovery Calculator (ACRC)

      For Drilling Contractors who want advanced core calculations, the Advanced Core Recovery Calculator is an optional feature which allows for a shift from data collection to calculation support.
      Available for Drill Types:

        • Surface - Coring
        • Underground - Coring
        • Sonic
        • Geotechnical 

      ACRC available in KruxLog allows users to: 

        • Set barrel constants for each drilling activity
        • Incorporate rod count
        • Automate String Length and Depth-To calculations

      To enable ACRC, go the Presets-->Report Setup in KruxMetrix so that it will be available in KruxLog within Drilling Activities of a DSR:
      Presets Report Setup for ACRC

       

      Note: In KruxLog-->Preferences, you can set the Unit of Measure (the default is metric) along with other settings.

      A key component of ACRC is Barrel Constants:

      ACRC Barrel Constants more

        • Core Barrel Size: industry standards
        • Second Barrel: associated second barrel sizes
        • Orientation Tool: industry standards
        • Orientation Extension for various sizes
        • Constant Stick Up: manual entry
        • Rod Length: industry standards
        • Barrel Length Calculation: calculated based on inputs
          ACRC Barrel Constants modal

      After Barrel Constants have been entered, users may start adding Core Runs for that Drill Activity with "Add Core":

      ACRC Add Core

      Input core run data:

      ACRC Barrel Constants Add Core modal

      1. Add Rods – Add/subtract rods or manually enter rods for that run
      2. Total Rod Count – Cumulative rod count in the hole
      3. Sub Length/Sub Description – Manual entry; Add sub length using consistent units. Input sub description as needed.
      4. String Length– Automatic calculation of string length based on Barrel Constants, Rod Count and Sub
      5. Stick Up – Manual entry of Stick Up for that run; add length using consistent units
      6. Depth From – Auto-populated field informed by Activity Depth From, or the previous core run Depth To
      7. Depth To – Calculated value based on String Length and Stick Up
      8. Recovered – Manual entry field of Core Recovered; Core Loss and % Recovered calculated based on Total Drilled and Recovered values
      9. Orientation – Yes/No dropdown to indicated whether orientation was successful

      Barrel Constants and Core Run Data can be reviewed and edited within the Activity by expanding/collapsing the arrow or clicking the Edit icon:

      ACRC Barrel Constants - Core expanded

                  Note: Editing a Barrel Constant will result in updated calculations throughout the associated core runs for that activity
