/*Abstract*/
Natural gas is an abundant energy source and the cleanest-burning fossil fuel. It is extracted from dense shale rock formations, and has become the fastest-growing fuel that could become a significant new global energy source. In addition, shale gas contains significant amounts of light hydrocarbons (e.g. ethane, propane, butane) providing lower cost raw materials to chemical industry. The long-term planning and development of the shale gas supply chain network around each play is a very relevant problem, that to the best of our knowledge, has not been addressed before through the use of advanced and comprehensive optimization models and tools.**An additional critical aspect in shale gas production is water management. Shale gas production is a highly water-intensive process, with a typical well requiring between 3-5 million gallons of water to drill and fracture. The vast majority of this water is used during the fracturing process, with large volumes of water pumped into the well with sand and chemicals to facilitate the extraction of the gas. Typically only 15-30% of this water returns as flowback water. Therefore, a long-term planning model for the development of shale gas fields should account for water availability. Furthermore, given the short periods of time in which very large amounts of water are used in the fracking of shale gas (e.g. 3 months), the scheduling of the fracturing of the wells and coordination of the logistics for transporting the water is a very important problem. This presentation provides an overview of recent optimization models for shale gas production.
