Changing Energy Picture in Washington State

  • Crude Oil Types (Bitumen vs. Bakken)

  • Oil Behavior, Fate and Effects

  • Oil Transportation

    • Rail

    • Pipeline

    • Vessel (tank ship, barge)

  • Responder and Public Safety Concerns

  • Changing Risk Picture

Oil Sands Products


Typical Ore Range

  • 55-80% sand

  • 5-34% fines

  • 4-18% bitumen

  • 2-15% water

  • 73% sand

  • 10% fines

  • 12% bitumen

  • 5% water


OSP Vocabulary

Bitumen – Extra Heavy Crude Oil, Biodegraded in-situ

Dilbit – Bitumen diluted for transportation (30:70)

Diluent – Low viscosity ‘product’ mixed with bitumen

CRW – Condensate Redwater; crude naptha

Syncrude – Synthetic “bottomless” crude cracked on-site

Synbit – Syncrude + Bitumen (50:50)

Dilsynbit – Diluent + Syncrude + Bitumen


Bakken Crude Oil Development


Bakken Crude

  • Light sweet crude

  • No pipeline infrastructure

  • Unit trains

  • ‘Wet’ Corridors in WA

  • Up to 3% benzene

  • Behavior is similar to ANS crude, just lighter


Bitumen/Bakken Behavior/Fate

  • Lack of testing & data

  • Bitumen Density: 0.94 to 1.03

  • Evaporation:

    • < 5% in 9 days for Bitumen

    • 75% in 2 days for Bakken

    • 30% in 2 days for ANS

  • Weathering & Sinking (primary factors)

    • Emulsifying

    • Sediment Interaction

    • Photo oxidation (grape skin)

  • Biodegradation: slower with higher PAH concentrations


Spill Case Study

Burrard Inlet, Burnaby, BC– July 25, 2007

- Pipeline rupture due to utility contractor excavation

- 58,000 gallons dilsynbit, 25,000 gallons to water

- Boomed within 40 minutes

- Calm winds,

warm weather,

clear water


Rail Transport

BNSF is Primary Carrier in Washington

  • Currently shipping lots of Bakken

  • Expanding operations – rail car production limited

  • 300% Increase in crude deliveries last year

  • 680 bbls gallons/rail car

  • DOT 111 improvements


  • Operating 1953

  • Currently pushing 300,000 bpd

  • Expanding to 890,000 bpd

    • Twinning

    • Pump upgrades

    • Increased Storage capacity

    • Additional tanker berths


Washington Upgrades

  • Currently 170,000 bpd

  • Increase to 225,000 bpd

  • 20” and 16” lines

  • 1 mile of 16” line increase to 20”

  • Additional pump at Laurel


Spill Considerations

  • Response Safety

    • Fire/Explosion

    • Benzene

    • Lack of specific information on diluent

  • Changing Spill Risk – different exposures

  • Response Detection and Cleanup Effectiveness

    • Submerged Oil

  • Inadequate spill behavior/fate/effects/toxicity/ dispersant efficacy information
