As an in-house software, it has a series of modules, which are able to integrated utilize the well and seismic data together to characterize the stratigraphic framework, reservoir distributions, effective reservoir distribution patterns and fluid properties and spatial distributions. It also can determine the reserves using calculus of both determined and stochastic analogues with the 3D reservoir geological model. Refine reservoir characterization service in carbonate, clastic and igneous formation have been professionally accomplished with prominent achievements. The service is featured on integrating expertise sources from various disciplines, lowering the risk on exploration, technics oriented and high quality services.
