A novel workflow was developed to select an optimal field development plan (FDP) which accounts for a number of associated uncertainties for an oil Greenfield concession that has a limited number of wells, production data and information. The FDP was revisited and updated to address the additional data acquired during the field delineation phase.
The study in Ref-1 demonstrates the comprehensive uncertainty analysis performed and the resulting optimized FDP. The FDP was developed to minimize the economic risk and uncertainty. Further field delineation activities have revealed a north and south extensions with an increase in hydrocarbon accumulation by 115%. A reservoir dynamic model was updated because of the increase in HC and input data from 17 wells.
A workflow has been created with a suitable development option to consider the recently appraised areas, which are:
Updated saturation height functions (SHFs) which improve the match between newly drilled wells and water saturations logs
Updated reservoir models which were based on well tests and new analytical interpretations
History matching well test data with new acquisition data
Optimized field development options, that cover additional areas
Inputs to reservoir surveillance plan
Be implementing following an extensive analysis the most robust development concept was selected and will now in the field.
