Offshore GTL – Transforming Natural Associated Gas to Liquid

June 19, 2013
As gas flaring becomes more unacceptable from political and environmental viewpoints, oilfields with no viable associated gas solution may be required to curtail production or in the extreme case, cease production entirely. There is evidence globally that this is starting to occur and proposals for new oilfield projects in remote or deepwater locations must increasingly demonstrate how the associated gas will be processed without continuous flaring. Gas re-injection sometimes offers a solution but this is expensive for deep wells and not desirable for all reservoir structures. Gas-to-liquids (GTL) processes enable monetization of remote natural gas or other gaseous hydrocarbons by converting them into sulfur-free synthetic crude oil that can be easily transported by tanker.
