East Zone - Broad crude selection cycle 15 days SRFO • Weekly update • 90 day horizon • 2 months out “Plan” • Use CSA evaluation tool • Price willing to pay, up to “X” • Volume willing to buy, up to “Y” “Mandate” • Bought or • Firm contract “Commit” • 2/3 day improvement in cycle time • worth $0.3/bbl • Cargo strategy • East - 70 term, 30 spot • West - 50 term, 50 spot “Programmed” “Scheduled”
Prices • Runs • Plant Constraint • Demands Monthly look 90 days out Low Constraints “stay open” 400kb opportunity “Run Rate” Feasible 200kb Short range forecast Programme 30 - 60 days A B C D Pick feasible option Tank blends Hourly Plant Crude planning vs scheduling time cycle
