A Numerical Model for Simulating Deep Injection Wells

Abstract

The growing tourism investments and urban developments at the coastal regions increased the demand on desalinated seawater, especially in the light of fresh water shortage. For the majority of Arab countries, water desalination became a necessary sector. The number and capacity of desalination units have expanded considerably in the previous decades, particularly in the Gulf States. One of the main stages of desalination is selecting a proper method to dispose undesired brine, which is a by-product from the plant, in a safe and economic manner to ensure the success and continuity of the desalination process. One of the widely used methods of desalination brine disposal nowadays is using deep injection wells. The construction cost of these wells is relatively high. So the decision of using this method and its success in disposing the entire capacity of brine from desalination plants must be precisely studied prior to well construction in the early planning stages to assess the feasibility of injection.
