The Davy Jones deep gulf shelf discovery by McMoRan Exploration et al. in South Marsh Island blocks 230, 231, 234, and 235 is of major importance for a number of reasons.It's on the shelf in shallow water (11 ft), and appears to be a major discovery, with a reported net gas pay of more than 200 ft in a section below 22,000 ft.The main significance of this apparent discovery is that it could open up other areas on the shelf to possibilities of deep discoveries below present producing depths. With today's technology, these areas can be defined and exploited.In most cases, this production potential will be gas in high pressure-high temperature hostile environments.Deep potential awarenessThe...
