Monetization of associated gases from offshore oil fields by electrical power generation

Oil fields always contain a mix of product including associated gases. Flaring these gases is now prohibited and in locations offshore, their management can be challenging. These gases can be used in onsite energy production. But in most cases, the amount of produced gas largely exceeds platform fuel gas requirement. Exporting this gas by a subsea pipeline can be quite costly, particularly as water depth increases. Converting this potential energy offshore in electricity and export it by an HVDC link can be a way to monetize this gas production. This article proposes to make a review of the technology and its maturity to satisfy this objective.
