Storage Complex Efficiency and Security

Storage Complex Efficiency and Security provides improved tools to design effective injection operations, optimize injection rates, manage pressure, make efficient use of reservoir storage space, and ensure the sealing capability of caprocks, both onshore and offshore. Development of these tools relies upon an understanding of carbon dioxide (CO2) plume and brine pressure front movement and stabilization, along with knowledge of the geomechanical and geochemical impacts of CO2 injection on storage complex in diverse geologic settings. The movement of CO2 in the reservoir, and accompanying changes in pressure are affected by many factors, such as the magnitude and distribution of various hydrologic properties of the reservoir rock, reservoir size, structural features such as baffles and fractures, sedimentary variations, the in-situ stress state, and diverse geochemical reactions. 

Research is needed to develop coupled simulators that model the complex interactions of these factors for a variety of storage complexes in diverse geologic settings and establish improved understanding of which factors, or combination of factors, have the greatest influence on CO2 movement and pressure changes in the reservoir.

Current research in Storage Complex Efficiency and Security includes development of:

The geomechanical framework for secure CO2 storage. The methodology uses laboratory test data, geophysical data, and petrophysical data to generate a reservoir model, perform simulations, and develop/refine a geomechanical Earth model

  • New tools for in-situ measurement of geomechanical properties.
  • Reduced order models and other advanced methods to reduce computational time and uncertainty.
  • Advanced, coupled thermal/hydrologic/mechanical/chemical numerical simulators.

Future research includes field validation of modeling algorithms; development of improved methodologies to determine an upscale fluid flow; geomechanical, and geochemical input parameters for complex reservoirs, such as fracture-dominated systems; development of new methods for manipulating flow in complex reservoirs; and development of coupled hydrologic/thermal/mechanical/chemical models that reduce cost and uncertainty of simulations while increasing their accuracy.

Technology Component Portfolio Interactive Map

The National Energy Technology Laboratory (NETL) is supporting a diverse portfolio of projects, which can be viewed in the Tableau Dashboard below. This map is entirely interactive; adjusting the toolbar on the left allows you to narrow your selection, pan, or zoom in/out. The map can be sorted by Technology Area; clicking on a location allows you to learn more about each individual project. 

Adjusting the Icon Spread Factor allows you to simultaneously view projects with the same locations. NOTE: Some of the projects, while they share a location, appear staggered to allow the viewer to show multiple projects at the same location. In those instances, as well those in which the location is marked as "Regional," the location is estimated.

Please note that the interactive map is best viewed using the Internet Explorer or Edge internet browsers.
