AbstractProjected demands for oil and gas in the near term provide E&P companies with confidence to engage in aggressive field development expansions of production capacity over the next 10 years. Upper Zakum is a giant offshore field that has been in production since 1982. The strategic target for further development is to increase plateau production rate by 50% within the next 10 years while maintaining industry-bestpractice reservoir management techniques and shareholder's economic guidelines. Like most existing carbonate fields in the Gulf Region this aggressive rate of field development will encounter challenges related to reservoir management and facility capacity uncertainties.The challenges require both organizational and technological responses in many areas and at multiple levels.The aggressiveness of strategic production goals demands that the technological and organizational issues be viewed in an integrated way that aligns and focuses competency requirements, work processes and technology implementation with strategic targets. In practice this requires that organizational structure must support the technological requirements for fully integrated multidisciplinary work processes. The presentation will describe the detailed organizational development processes used by the Upper Zakum Field Development Department and the resulting project-based organization model chosen for implementation.
