2 Copyright 2004 SIEP B.V. P04148_001 Contents 1.Morocco – the background to deepwater exploration 2.The ingredients for exploration success Commercial Technology Geology 3.What happens next?

3 Copyright 2004 SIEP B.V. P04148_001 Morocco - 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

15 Copyright 2004 SIEP B.V. P04148_001 Drill potential hub class prospect DRY Evaluate remaining exploration potential and decide whether or not another hub class prospect will be drilled. 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
