    Abstract: An example system includes interconnected modeling modules that share knowledge to create a unified earth model dynamically representing a subsurface site. The system models and may simulate subsurface operations associated with, for example: hydrocarbon production and stimulation, natural gas storage, carbon capture and storage, aquifer maintenance, geothermal energy production, and in-situ leachable ore processing. The system integrates a reporting module, and also an economic module to evaluate cost versus benefit of each subsurface operation. A related example method for performing subsurface engineering includes generating a model of a subsurface site including a geological horizon, obtaining an offset relative to the geological horizon, and locating an operation based on the offset. When field data update the model in real time, positions of 3D objects and 3D surfaces are dynamically updated in the model, including the positions of the modeled operations.

    Abstract: A gamma-ray detector comprising: a housing having a window through which gamma rays can enter; the housing comprising; a two-dimensional array of electrically conducting carbon nanotubes, which act as a cathode, on a substrate; a metal plate electrode, which acts as an anode, positioned opposite the substrate so that there is a gap containing a gas between the electrode and the nanotubes; and a voltage source connected to the substrate and the electrode such that when in use the voltage between the substrate and the electrode is maintained below the arc-threshold voltage so that no electric current can flow through the gap between the nanotubes and the electrode; wherein the electrode and the substrate are arranged such that when a gamma ray enters the housing and hits one of the nanotubes a spark discharge is triggered between the nanotubes and the plate electrode creating an electrical current that can be measured.
