• Results
• Improved ability to detect product downgrades
  through tank gauge and meter comparisons
• Summary
• Identified Events 4
• Reduced Product
• Downgrade 34000 bbls
• Monetary Savings 125 K

13

• Event 1
• Distillate Product System
• FCCU light cycle oil to 6 Fuel Oil
• Intended disposition light cycle oil tankage
• Reduced downgrade by 16000 bbls
• Incident involved a leaking valve in an inactive
  piping system.
• Discovered during model reconciliation comparing
  the light cycle oil tank gauge against product
  meter.
• Operations investigated and found valve leaking
  through.

14

• Event 2
• Distillate Product System
• Diesel Fuel to 6 Fuel Oil
• Intended disposition diesel tankage
• Reduced downgrade by 5000 bbls
• Incident involved tank to tank transfer of
  diesel.
• Discovered during tank gauge verification of the
  diesel and 6 Fuel Oil tanks comparing tank gauge
  changes.
• Operations investigated and discovered a valve
  open between the two product systems.

15

• Event 3
• Distillate Product System
• Diesel Fuel to 6 Fuel Oil
• Intended disposition finished tankage
• Reduced downgrade by 7000 bbls
• Discovered during verification of tank gauge data
  and comparing product meter information.
• Operations investigated and discovered a valve
  open between the two systems.

16

• Event 4
• Vacuum Gas Oil Product System
• DMO to 6 Fuel Oil
• Intended disposition FCCU feed system
• Reduced downgrade by 6000 bbls
• Incident involved misalignment of product flow
  off unit.
• Discovered during model reconciliation comparing
  tank gauge to 6 Fuel Oil system meter
  information.
• Operations investigated and discovered the
  misalignment.
