Stranded Gas Perspective
Demand and Technology (pipeline LNG) lead to a
global gas marketplace

• Stranded gas no economic transport solution
  (remote field, marginal field, limited pipeline
  capacity)
• 40-60 of worlds gas reserves are stranded
• New applications and technologies for bringing
  stranded gas to market are emerging (GTL, GTO,
  NGH, others)

Natural Gas Hydrate (NGH)

• NGH production at moderate pressures and
• temperatures (60 bar 10-15 oC)
• NGH transport at atmospheric pressure and -20
  oC.
• Safe storage and transport method for natural
  gas
• 1 m3 of NGH may contain up to 180 m3 of natural
  gas
• Competitive technology for medium size gas
  fields
• Aker Kvaerner has ownership to the technology
  (patents)
