Subsurface Technology and Engineering Research, Development, and Demonstration (SubTER)

SubSurface Crosscut InitiativeThe Department of Energy (DOE) has established the Subsurface Technology and Engineering Research, Development, and Demonstration (SubTER) Tech Team as an integrated platform across DOE subsurface interests to address crosscutting grand challenges associated with the use of the subsurface for energy extraction and storage purposes. Functions of the DOE SubTER Tech Team include:

  • Identify subsurface challenges and advocate solutions;
  • Identify potential cross-cutting subsurface initiatives;
  • Facilitate both intra-departmental and interagency collaboration of cross-cutting subsurface R&D activities; and
  • Engage industry stakeholders operating in the subsurface.

Adaptive Control of Subsurface Fractures and Flow

Ability to adaptively manipulate – rapidly and with confidence -subsurface fracture length, aperture, branching, connectivity and associated reactions and fluid flow.

FRACTURE CONTROL IS CRITICAL FOR MANY SUBSURFACE ENERGY STRATEGIES

shale hydrocarbon, geologic carbon sequestration, enhanced geothermal energy, nuclear waste disposal, compressed air energy storage

Shale Hydrocarbon Production

Control fracture length & branching patterns, and flow

Safe Subsurface Storage of CO2

Enhance injectivity, optimize storage, plug leakage pathways
