Green Field Development Workflow Involving Appraisal,Increased Scope,Optimizing Target Production And Reservoir Monitoring: A Case Study

摘要

A novel workflow was developed to select an optimal field development plan (FDP) which accounts fora 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 acquiredduring the field delineation phase.The study in Ref-1 demonstrates the comprehensive uncertainty analysis performed and the resultingoptimized FDP.The FDP was developed to minimize the economic risk and uncertainty.Further fielddelineation activities have revealed a north and south extensions with an increase in hydrocarbonaccumulation by 115%.A reservoir dynamic model was updated because of the increase in HC and inputdata from 17 wells.A workflow has been created with a suitable development option to consider the recently appraised areas,which are: 1.Updated saturation height functions (SHFs) which improve the match between newly drilledwells and water saturations logs.2.Updated reservoir models which were based on well tests and new analytical interpretations.3.History matching well test data with new acquisition data.4.Optimized field development options,that cover additional areas.5.Inputs to reservoir surveillance plan.Be implementing following an extensive analysis the most robust development concept was selected andwill now in the field.
