Hethos has access to a full range of production technologies and the expertise to solve through innovation the challenges of Hydrogen and Helium extraction

Reservoir simulation

  • Current simulation systems are being adapted for hydrogen reservoirs
  • Collaboration with Ohio State university to develop a H2 based simulator using their existing CO2 model
  • Easy to adapt to another reservoir, and insert large macro-specifics such as faults etc

Hydrogen adapted seismic

  • Targeting hydrogen chimneys and local accumulations, especially at the intersection of large faults and unconformities
  • Will use P versus S waves to identify H2 chimneys with 3S Seismic
  • Discussions with other teams such as Geolink or Wavelab

Polymer casing and tubing*

  • Metal alloys casing and tubing will not resist hydrogen embrittlement, and current plastic casing does not resist lower than 500m to 700m
  • Hethos will use a polymer* that can resist downhole temperatures and pressures down to 2000m at least
  • Casing and tubing are saline water and hydrogen resistant

Well architecture

  • For transit reservoir with local accumulations, Hethos targets the hydrogen flux with multi-level laterals placed on both sides of the perpendicular of main local fracture direction
  • Laterals can be done by radial drilling, or more classical techniques such as whipstock that is less expensive than horizontals as lower precision needed

Sensors

  • All weather, wide detection range hydrogen sensors are mandatory for surface crew safety. Existing sensors have poor resistance to outside conditions and limited sensitivity range
  • Developing sensors for ‘fairy circle’ analysis
  • Hethos will use customized sensors based on semi conductors, answering the above issues
