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


Slide5Copyright 2004   SIEP B.V.             P04148_001Ingredients for success - Commercial  Straightforward tax/royalty regime  10-year ‘tax holiday’  Clearly defined work programme  Informed, professional and challenging local partnership

Slide6Copyright 2004   SIEP B.V.             P04148_001Ingredients for success - Technology  Exploration risk reduction  An understanding of the environmental sensitivities  Environmentally sensitive, safe drilling operations  Deepwater development skills
