| Popis: | This paper addresses the scheduling of offshore oil well construction using drilling vessels. Drilling costs constitute a substantial part of the total development costs for an offshore field, thus planning the efficient use of drilling rigs is crucial to ensure economic feasibility of oil and gas exploration and production (E&P) projects. The objective of this study is to minimize the completion time of all operations involved in the development of subsea wells considering the availability of the drilling rigs. These activities are drilling and completion of the well, and maintenance activities. Technical constraints and availability of the drilling vessels and release dates and precedence constraints of the activities are considered. In addition, vessel eligibility restrictions are respected. A mixed integer linear programming model was developed considering the goals and constraints above. Numerical experiments using instances based on real-world situations show adequate behavior, which demonstrates that it faithfully represents the situation portrayed and can be used, combined with more advanced optimization techniques, to achieve better results. |
