og gas fluid inventory determination
Og Gas/Fluid Inventory Determination
  • Accurate inventory determination is challenging due to a few factors:
    • Substance orientation
    • Substance properties
    • Measurement technique
  • Several RFPs have been granted to develop new technologies to provide better accuracy in 1g and 0g conditions
what s the goal
What’s The Goal?
  • Develop a non-intrusive, reliable, simple instrument to accurately determine the inventory level
    • Use ‘dumb’ sensors
    • Utilize simple physics
    • Take advantage of ‘random’ nature of fluid
compressed sensing
Compressed Sensing
  • Process of acquiring and reconstructing a signal that is supposed to be sparse or compressible.
  • An undetermined system has more unknowns than equations and generally has an infinite number of solutions.
    • However, if there is a unique sparse solution to the underdetermined system, then the Compressed Sensing framework allows the recovery of that solution.
    • Not all underdetermined systems of linear equations have a sparse solution.
  • Develop MCNP model to stochastically track particles/photons through system and record counts at detector locations
  • Develop a library of known fill levels and detector responses
  • Query library with new detector responses to determine fill level utilizing compressed sensing approaches
more complex system
More Complex System
  • An interest in determining fill level and location of liquid in tank in zero gravity
  • Utilize similar approach to earth-g system but allow liquid to be located anywhere in the tank.
  • Solve for both fill and location
