Sub-Surface Technologies (SST) Investigating and Optimizing Geological Storage and Resource Extraction

Whether for maximizing resource extraction or commodity storage, understanding geologic systems is a critical skill set. Maximizing geologic storage capacity is critical to enable the integration of renewables, contribute to grid stability, and make creation of a hydrogen economy possible. More research is needed before safe and responsible large-scale storage of hydrogen can be accomplished below ground. In addition, CO2 can also be permanently stored underground to minimize climate change impacts.

  • GTI Energy formed and manages the Hydraulic Fracturing Test Site (HFTS) program funded by the DOE and 26 industry partners. HFTS-1 is located in the Midland portion of the Permian basin and HFTS-2 is located in the Delaware portion of the Permian basin.
  • GTI Energy has developed proprietary technologies for improving hydraulic fracturing effectiveness to maximize recoveries from unconventional wells. PerfExtra is one example of these technologies. Our method promotes breakdown of non-productive perforations and an increase in stimulated rock volume to achieve higher efficiencies.
  • GTI Energy’s new PropLog is a low risk, low-cost patented technology used to identify existing un-stimulated or un-drained sections of a reservoir for targeting tailored completions. Data is generated by quantifying the accurate size and concentration of proppant particles contained in drilling mud.
  • Enhanced Oil Recovery (EOR) technologies are crucial for supporting energy systems transition by providing the potential for doubling Estimated Ultimate Recovery (EUR) from existing assets. GTI is performing fundamental research on developing sustainable and environmentally friendly EOR technologies for unconventional formations. We have a lab facility capable of performing core flooding, aging, saturation evaluation, and evaluation of the incremental oil recovery

 

Permanent geologic storage of CO2

  • GTI Energy is examining new geographic areas and geologic formations for large-scale storage of CO2, such as previously untested deep saline aquifers and in depleted unconventional wells. These new options will be required for CO2 storage to become a truly universal element of the low carbon energy transition.

 

Large-scale seasonal geologic storage of H2

  • GTI Energy is performing preliminary research into the challenges and opportunities for large-scale, seasonal storage of H2. Geologic storage of H2 in “porous media” such as depleted reservoirs and/or aquifers will be a promising solution to support the creation of a hydrogen economy.

 

Enhanced geothermal systems

  • Geothermal energy can provide renewable electricity and be used in heating and cooling applications. Enhanced geothermal systems have great potential to enable the heat of the earth to meaningfully contribute to clean and reliable energy, but additional R&D is needed. GTI Energy is exploring various technologies to improve the efficiency of enhanced geothermal systems and aiming to perform field testing going forward.
