Securing future production of oil and gas reserves

With exploration costs on the rise and energy demands steadily increasing, oil and gas companies are seeking ways to maximize the production of their mature fields and, where it makes sense, drill new wells in existing reservoirs. With this objective in mind, Talisman Energy conducted an integrated field study of the Gyda South reservoir in Norway, which had been in production since 1995. The goals of the study were to recalculate field reserves, gain a better understanding of well behavior and obtain a more accurate estimate of future production. A dedicated project team—consisting of a reservoir engineer, a geologist and a geophysicist—was assembled for the purpose of this study: to ensure that Gyda South reserves are fully tapped and that future production is secured despite challenging field characteristics and mitigating circumstances, such as rapid water breakthrough.
