U.S. Department of Energy’s GTO Grant: Advancing Zonal Isolation for Manmade Geothermal Reservoirs

Zonal isolation technologies can radically improve the
performance and economics of EGS, or manmade geothermal
reservoirs. These technologies provide the ability to target specific zones for stimulation activities, which can enable the command and control of fracture location and the economy of resources. In turn, this reduces development costs and operational risks associated with EGS development and promotes more power from fewer wellbores.

Under this funding opportunity, GTO is interested in two topic areas:

Topic 1 – Invention and Innovative Design of Zonal Isolation Technologies and Techniques for EGS Stimulation; and,

Topic 2 – Adaption of Existing Zonal Isolation Technologies
for EGS Stimulation.

The projects selected from this FOA will aim to develop
reliable zonal isolation tools and technologies that:
• Present low risk to wellbore integrity or the
conductivity of fractures;
• Can operate at high-temperatures in corrosive, hard
rock environments for extended periods of time; and
• Withstand large pressure differentials.

EERE-Exchange.energy.gov.

The eXCHANGE system is currently designed to enforce hard
deadlines for Concept Paper and Full Application submissions.

The APPLY and SUBMIT buttons automatically disable at the
defined submission deadlines. The intention of this design is to consistently enforce a standard deadline for all
applicants.

Applicants that experience issues with submissions PRIOR to
the FOA Deadline: In the event that an Applicant experiences technical difficulties with a submission, the Applicant should contact the eXCHANGE helpdesk for assistance (exchangehelp@hq.doe.gov). The eXCHANGE helpdesk and/or the EERE eXCHANGE System Administrators (eXCHANGE@ee.doe.gov) will assist the Applicant in resolving all issues.

Applicants that experience issues with submissions that result in a late submission: In the event that an Applicant
experiences technical difficulties with a submission that
results in a late submission, the Applicant should contact the eXCHANGE helpdesk for assistance (exchangehelp@hq.doe.gov).

The eXCHANGE helpdesk and/or the EERE eXCHANGE System
Administrators (eXCHANGE@ee.doe.gov) will assist the Applicant in resolving all issues (including finalizing the submission on behalf of, and with the Applicant’s concurrence). DOE will only accept late applications when the Applicant has a) encountered technical difficulties beyond their control; b) has contacted the eXCHANGE helpdesk for assistance; and c) has submitted the application through eXCHANGE within 24 hours of
the FOA’s posted deadline.

Informational Webinar: The Informational Webinar mentioned in the FOA is scheduled for July 5, 2018 at 2:00PM ET.
