Maximized recovery is the goal in any mature field. In the past, operators shifted resources elsewhere once the "easy oil" was found and produced. It's widely held that there are very few giant, new discoveries left in the world. With advances in new technology, getting as much as possible from your existing assets is becoming more and more feasible. And when you consider that a mere 1% increase in the recovery rate of mature fields could add to the world's oil and gas supply for two years or more, it just makes sense.
Mature fields require more careful planning, especially during the re-assessment phase in order to identify producible reserves that were previously missed or thought unobtainable. Halliburton knows how to help operators apply the right methods and technologies to redefine the value of these hidden assets.
