Optimal Planning of Infrastructure for the Supply Chain of Shale Gas Karla Arredondo-Ramírez, José María Ponce-Ortega and Mahmoud M. El-Halwagi
Abstract As a result of the discovery of substantial reserves of shale gas, it is important to develop effective strategies for the establishment of infrastructure supporting the growth of shale gas production and monetization. This chapter presents an optimization approach for the optimal planning of shale gas exploitation and infrastructure development in places that lack the infrastructure needed for production, treatment, and distribution. A multi-period optimization approach is presented to account for the variability in market. The different components of the infrastructure, the production schedules, and the time-value of money to maximize the net present value of the infrastructure are considered in the optimization model. The applicability of the proposed approach is shown through a case study from Mexico, where there are enormous reserves of shale gas that require the development of infrastructure. The results show attractive economic results for the exploitation and distribution of gas to satisfy a certain demand. Nomenclature Sets i m p r t
