Technology Impact on Cost ReductionTechnology Impact on Cost ReductionNotes from previous slideNotes from previous slide
In the meantime, as we can see from this chart developed by the Cambridge Energy Research Associates, technology has had a major impact on industry performance.
And I am convinced that technology will continue to be a significant differenciator in the future of the industry. The difference is and will continue to be technology.

VALUE:
• Avoid high cost recompletions in multi-zone wells
• Commingle zones w/ different pressures & drive mechanisms
• Reduce total well count in a project
ISSUES:
• Mechanical complexity could reduce well reliability & increase high cost intervention
• Lack of a reliable multi-lateral HP junction
• Lack of a reliable multi-phase meter
• Complexity of GOM Gravel Packs
SEPCo PLANS:
• Brutus - 1 well
• Nakika - 5 wells

Breakthrough surface systems - focusing on enabling marginal fields by lower life cycle costs and by increasing the crude sales price by crude enhancing technology.
Key problems with marginal fields are that they are sensitive to CAPEX and frequently have poor quality crude properties. The poor quality can affect the sales price by up to $2/bbl.
This initiative will focus on lowering the initial cost of surface systems by working on breakthrough technologies and on improving the sales price of the crude production through the use of crude enhancing technologies.
Surface technologies such as using different hull shapes to lower the environmental forces and using slack vertical risers without tensioners may dramatically lower the cost of surface structures. The use of new composite materials may also add further cost reductions.

Expectations of SocietyExpectations of SocietyWith all these achievements in technology and value creation, we must not forget that we are operating in potentially exposed environments, working with highly flammable products. Until our technology allows us to remove manned facilities from the offshore, this exposure will increase as we move to deeper and more remote waters. Our industry must maintain its management of Health, Safety and the Environment. Our own responsibilities and the expectations of society will not let us put our people at risk.
A series of major offshore incidents in the late 1960s and the 1970s highlighted these risks, but it was not until the Piper Alpha disaster in 1988 that the industry woke up to the fact that something could and should be done. Today, HSE is approached systemically - HSE management is the watchword, and Safety cases are mandatory in most operations. Looking after the safety of an offshore installation requires continuous monitoring and improvement.
Our industry needs to approach this together - there cannot be any element of secrecy or competitiveness about HSE management. We believe that in the long term all accidents can be prevented, but it will require the efforts of everyone to be a part of the solution.
Finally, business conditions will become more challenging as investors see other, new opportunities for their investments. We all need to satisfy our various shareholders and stakeholders. Cost reduction and technological improvements, along with ensuring that development is sustainable are essential to achieve this objective.
