Optimal Development Planning of Offshore Oil and Gas Field Infrastructure under Complex Fiscal Rules
نویسندگان
چکیده
The optimal development planning of offshore oil and gas fields has received significant attention in recent years. In this paper, we present an efficient investment and operational planning model for this problem which is fairly generic, and is extended to include fiscal considerations. With the objective of maximizing total NPV for long-term planning horizon, the proposed non-convex multiperiod MINLP model involves decisions regarding facility installation and expansion, field-facility connections, well drilling schedule and production profiles of oil, water and gas in each time period. The model can be solved effectively with DICOPT for realistic instances and gives good quality solutions. Furthermore, it can be reformulated into an MILP after piecewise linearization and exact linearization techniques that can be solved globally in an efficient way. Solutions of the realistic instances are reported for the proposed models, as well as the computational impact with consideration of the complex fiscal rules within development planning.

The paper presents a new optimization model and solution approach for the investment and operations planning of offshore oil and gas field infrastructure. As compared to previous models where fiscal rules and uncertainty in the field parameters are considered separately, the proposed model is the first one in the literature that includes both of these complexities in an efficient manner. In par...

متن کاملA Multistage Stochastic Programming Approach for the Planning of Offshore Oil or Gas Field Infrastructure Under Decision Dependent Uncertainty
The planning of offshore oil or gas field infrastructure under uncertainty is addressed in this paper. The main uncertainties considered are in the initial maximum oil or gas flowrate, recoverable oil or gas volume and water breakthrough time of the reservoir, which are represented by discrete distributions. Furthermore, it is assumed that these uncertainties are not immediately realized, but a...

In this paper, we present an efficient strategic/tactical planning model for offshore oilfield development problem that is fairly generic and can be extended to include other complexities. The proposed multiperiod non-convex MINLP model for multi-field site includes three components (oil, water and gas) explicitly in the formulation using 3 rd and higher order polynomials avoiding bilinear and ...
