Reduced land slots availability for drilling of new wells, operator's focus to increase production, aim to reduce effective cost per barrel and to minimize the environmental footprint, worldwide drilling contractors/operators are looking for various solutions available to address these concerns. Drilling multilateral wells is one of the solutions to these concerns. This paper presents the process and steps followed in planning and decision making for drilling a multilateral well in one of the North field in Kuwait, which includes Identification of filed and understanding formation, Categories of multilateral wells and selection of level and types of multilateral well, Pre requisition of data for level 1 multilateral well, Selection of well slot and reviewing additional tools/service requirement, Selection of well trajectories for multilateral well, Selection of open hole junction point, Selection of section TDs, Review of directional BHA & its suitability for open hole side track, Well control scenarios, Well stimulation plans, Review of Coil tubing (CTU) operation for stimulation and tools requirement, Contingencies plan for reservoir section, Cost saving, higher production, environmental footprint, well completion days. |
