A water flooding pattern using maximum reservoir contact (MRC) wells will be utilized for the future developments of reservoirs in a giant brown field offshore Abu Dhabi. The increase in the reservoir contact together with the application of intelligent completion (IC) for the reservoir management is an effective way to improve the sweep efficiency, enhance oil production and minimize early water breakthrough. Meanwhile, the field is much congested with existing wells drilled from offshore well head towers and several artificial islands (AIs). In addition, many MRC horizontal wells have been and will be drilled in the overlaid reservoirs. Hence, well collision alarms are increasing day by day when planning a new well. To meet with the field development perspectives as well as coping with such a critical field circumstance, unique well architectures with a multi-lateral IC, namely Multi-lateral Line Drive (MLLD) system are designed and the techno-economic analysis has been completed for specific cases. This system will enable to reduce the overall drilling and completion cost for the field development with no adverse impact and mitigate the well collision risk by minimizing the number of mother wellbores penetrating through the overlaid reservoirs and provide real time monitoring and control to add values to the reservoir management. This paper presents the drilling and completion strategy for the future reservoir developments, the MLLD system designs and associated technical challenges. In addition, outcomes from the case studies are addressed.
