Making LNG Affordable as a Means to Monetize Associated Gas Offshore

Abstract

Today, the gas associated with oil production is becoming an environmental concern for existing fields when it is flared. There are substantial quantities of associated gas still burnt at fields every year. When offshore, the reinjection of such associated gas into the reservoir is not always technically feasible, it is expensive, and may become a blocker for new offshore oil developments. Associated gases can be monetized in the form of LNG produced directly offshore, it can become an enabler of new oil projects, and a means to reduce CO2 emissions and meet commitments. LNG production at sea can be achieved at a competitive CAPEX, by using an innovative mega-module concept. Furthermore, when treating rich associated gases, the production and export of high-value liquid by-products - LPG and condensates and even possibility ethane - can greatly improve the economics of LNG production itself by creating additional revenues, at a marginal increment cost thanks to the integrated process and utilities functionalities, while keeping the possibility to adjust to several LNG market specifications.
