Development of integrated gas transport systems

Gas storage solutions

More focus on enhanced oil recovery - easy access to gas

in some cases increased field

~ fiSt.Some comments.. NPI

• • Environmental standards are easier to adapt in pre-development phase

than in production phase

• Gas infrastructure - investments in infrastructure, 3rd party ~ss, tax deductability (t'irIJ~) riWv!'~''''aJ ?)

• Probably harder to reduce flaring in remote areas without gas pipelines .--;­

• Approx. 20 - 40 % of flaring is continuous flaring while the remaing share is caused by events ana misliaps to secure safety and operational purposes
