Tempest VIEW is the interface for all Tempest modules, in addition to providing simulation pre & post processing for 3rd party simulators. It is a fast and memory efficient system, capable of quickly processing results from multiple simulations consisting of millions of cells and thousands of wells. It is easy to learn and use and combines charts and 3D views with analysis tools to help with history matching and understanding the reservoir. Built in calculators and unit convertors allow for extensibility.
