Development Plan (Subsurface)The development plan on the Omani side of the field involves the deepening of West Bukha-2 and thedrilling of a second, high angle well close to the Iranian border, the wells being produced to a platform,and thence to the Bukha platform—this is called (by the field owners) Phase I of the development. Duringthis phase, field performance will be monitored to determine the need for future wells (Phase IIand beyond).The platform will have space for 6 wells, and we believe an additional 2 wells will be drilled in Phase II;further drilling thereafter will depend on medium-term field performance. The wells will be equipped withthe ability to selectively produce from one formation or both—there is no final decision yet on whichoption to run with.89
