 GEOS is a simulation framework focused solving tightly-coupled multi-physics problems with an initial emphasis subsurface reservoir applications.
 Currently GEOS actively supports implementations for studying carbon sequestration, geothermal energy, hydrogen storage, and similar subsurface applications.
 The unique aspect of GEOS that differentiates it from existing reservoir simulators is the ability to provide tightly-coupled compositional flow, poromechanics, faults and fractures slip, and thermal effects, etc.

 Often these simulations involve coupling between compositional multiphase flow and transport, poroelasticity, thermal transport, and interactions with faults and fractures.
 
 As an example of a field case where GEOS has been applied, we present a coupled compositional flow/mechanics simulation of CO2 injection and storage at a large real-world storage site.

 Simulations such as this will play a critical role in predicting the viability of potential CO2 storage sites.
 
 ![Real world CO2 storage site: (a) discrete mesh, transparency is used for the overburden region to reveal the complex faulted structure of the storage reservoir; (b) results of a compositional flow simulation after 25 years of CO2 injection. The CO2 plume is shown in white near the bottom of the well. Colors in the reservoir layer indicate changes in fluid pressure, and the colors in the overburden indicate vertical displacement resulting from the injection. Note that color scales have been removed intentionally.\label{RW_results}](RW_final.pdf){ width=100% }
