On 2 November 1992, Iran filed an application instituting proceedings against the United States in respect of a dispute arising out of the attack on and the destruction of three offshore oil production complexes. In it, Iran contended that these acts constituted a fundamental breach of various provisions of the Treaty of Amity, Economic Relations and Consular Rights between the United States and Iran, signed in 1955.

Offshore Oil

The ongoing, large demand for oil in the United States has helped push oil companies from onshore to offshore, increasing the complexity of the operations and the risks. This has been encouraged by US policy, which has historically encouraged an increase in both national oil demand and domestic oil production. This chapter focuses on expanded offshore oil drilling in the United States and its risks, highlighting the 2010 Deepwater Horizon oil blowout. Such events are examples of explicitly “human-caused” disasters that nonetheless can be expected to increase as we resort to lower quality and harder to reach fossil fuels, offering an interesting example of Charles Perrow’s concept of “normal accidents.”

Offshore Oil

In this paper, a new Lagrange relaxation based decomposition algorithm for the integrated offshore oil production planning optimization is presented. In our previous study (Gao et al. Computers and Chemical Engineering, 2020, 133, 106674), a multiperiod mixed-integer nonlinear programming (MINLP) model considering both well operation and flow assurance simultaneously had been proposed. However, due to the large-scale nature of the problem, i.e., too many oil wells and long planning time cycle, the optimization problem makes it difficult to get a satisfactory solution in a reasonable time. As an effective method, Lagrange relaxation based decomposition algorithms can provide more compact bounds and thus result in a smaller duality gap. Specifically, Lagrange multiplier is introduced to relax coupling constraints of multi-batch units and thus some moderate scale sub-problems result. Moreover, dual problem is constructed for iteration. As a result, the original integrated large-scale model is decomposed into several single-batch subproblems and solved simultaneously by commercial solvers. Computational results show that the proposed method can reduce the solving time up to 43% or even more. Meanwhile, the planning results are close to those obtained by the original model. Moreover, the larger the problem size, the better the proposed LR algorithm is than the original model.
