Slide2Copyright 2004 SIEP B.V. P04148_001Contents 1. Morocco – the background to deepwater exploration 2. The ingredients for exploration success Commercial Technology Geology 3. What happens next?
Slide3Copyright 2004 SIEP B.V. P04148_001Morocco - the background to deepwater exploration History of offshore exploration without commercial development Unexplored deepwater acreage Growing industry success in deepwater developments elsewhere Improved risk reduction tools based on 3D seismic

HUB SIZE Appraise and Develop Re-evaluate remaining exploration strategy Evaluate remaining exploration potential and select most promising prospect that is either a hub on it’s own or can help in justifying a cluster development TOO SMALL FOR HUB Exploration and Development Strategy
