The Hibernia field, located 315 km offshore Newfoundland and Labrador, Canada, began production in November 1997.<br>The southern part of the field is a waterflood development, with seawater injection used for pressure maintenance. The<br>northernmost portion of the field is a gasflood development that maintains pressure by re-injecting gas produced from the<br>waterflood for voidage balance. As the field matures, water production from the waterflood region is increasing significantly<br>and therefore the associated gas produced from these oil wells has been declining. As the availability of gas from the<br>waterflood area decreases, gasflood region production also decreases due to the declining amount of produced gas available<br>for injection for pressure maintenance. Another source of gas was needed to maximize gasflood region production.
