This paper describes an efficient approach to implement IAOM project and evaluate subsurface well performance and surface network facilities of a supergiant oil field flowing from multilayered carbonate reservoirs. The field is produced via several gathering stations and pumping stations. The current manifold pressures at the RDS stations are high, which will increase by the introduction of gas lift and by the additional production from new wells. In IAOM implementation process, individual well strings and robust network model was built for the asset on the IAOM platform. This model was further utilized in meeting various production optimization challenges such as well surveillance, production and Injection optimization, forecasting and allocation and field development planning. This paper demonstrates how IAOM project was used to run different production optimization scenarios, describing the objective, methodology, analysis and results to address various challenges in production optimization. Following case studies were carried out for this purpose: Well potential rate analysis and optimization: To determine well potential rate based on the well performance, reservoir guidelines and back pressure in the network system.New producer well tie-in to existing network: To investigate optimal option for a new producer well flowline tie-in to existing well flowlines carrying fluid to remote degassing station and study well flowline performance after tie-in.Wellhead shut-in pressure analysis and optimization: To estimate wellhead shut-in pressure at which well ceases to flow when reservoir pressure is increased to new pressure.New pattern injectors tie-in to existing clusters: To estimate tie-in options for new water injector wells for new developments project to the existing clusters based on availability of water supply and closest distance.

This paper describes an efficient approach to evaluate the water supply-to-injection cluster facilities capacity and also to define the required upgrades and areas of optimization.The supergiant filed understudy is located in Abu Dhabi and is producing for decades from multilayered carbonate reservoirs. The field is under peripheral water injection to maintain reservoir pressure and also to enhance the oil recovery.Total of 53 water injection clusters have been commissioned in the field to support water injection operation for reservoir management purpose. The water clusters consists of producing wells from water bearing formations and multiple injection wells completed in different reservoirs. Frequent down time in the water supply wells and existing bottle necks in the water supply to injection system has led Abu Dhabi Company for Onshore Operation to evaluate the clusters looping option to enhance the water injection capacity of the field and optimal re-distribution of the water through the clusters.By this strategy, the high capacity water supply wells will be able to feed the candidate clusters required extra water or the clusters with the closed water supply well under maintenance.To achieve this strategy, a fully integrated water supply to water injection system was built using a commercial fluid flow simulator. The integrated model consists of water supply well equipped with ESP, water injection facilities network with surface pumps, strainers and choke manifolds as well as injection wells. The system was validated against most reliable measured data at a snap shot of time.The full integrated water supply to injection model was used to evaluate the opportunities to loop the high capacity clusters to high demanding clusters, identify the bottlenecks in the system and also to determine the various options in the clusters facilities to enhance the water injection capacity of the field.
