/*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.
