The New York Times is reporting that the number of mergers and acquisitions of energy companies is growing and that energy companies are increasingly seeking to acquire new sources for energy exploration. Companies are focusing on buying small, growing companies or on acquiring companies that expand their reserves in a period in which it is hard for them to find new places to drill. Targeted companies include companies in Africa as well as those that control drilling fields in deep waters in the Gulf of Mexico.
A recent study of ours, Environmental and Cost Synergy on Supply Chain Network Integration in Mergers and Acquisitions, that I co-authored with Dr. Trisha Woolley, appears in the recent volume, Sustainable Energy and Transportation Systems, Proceedings of the 19th International Conference on Multiple Criteria Decision Making, Lecture Notes in Economics and Mathematical Systems, M. Ehrgott, B. Naujoks, T. Stewart, and J. Wallenius, Editors, Springer, Berlin, Germany (2010) pp 51-78. In this paper, we developed a multicriteria supply chain network model to assess the possible cost and environmental synergies associated with supply chain network integration as in mergers and acquisitions. This work has direct relevance to energy companies who are considering whether to acquire or merge with an existing energy company (or not).
We have also (with Woolley and Dr. Patrick Qiang) developed metrics to assess the synergy associated with the supply chain network integration of multiproduct firms in the case of mergers and acquisitions. That paper, entitled, Multiproduct Supply Chain Horizontal Network Integration: Models, Theory, and Computational Results, will appear in the journal International Transactions in Operational Research.
