  • Patent number: 10416216
    Abstract: This disclosure concerns photonics and in particular the addressing of individual targets in solids. In aspect one there is provided a device comprising a solid substrate with one or more atomic scale targets in the substrate. A laser light is focused on a region of the substrate that contains a single target to selectively cause photoionization of the target. A charge sensor with sub-electron charge sensitivity is focussed on measuring the charge in the region of the substrate that contains a single target. In use, the device operates such that the laser is turned on to cause photoionization of the target, and the charge sensor detects the change in charge in the region of the substrate that contains the single target. In another aspect is the method for optically investigating individual nuclear spin states of single atoms by investigating both the Zeeman effect and the hyperfine interaction of the single atoms.

  • Patent number: 10401313
    Abstract: Downhole fluid volumes of a geological formation may be estimated using nuclear magnetic resonance (NMR) measurements, even in organic shale reservoirs. Multi-dimensional NMR measurements, such as two-dimensional NMR measurements and/or, in some cases, one or more well-logging measurements relating to total organic carbon may be used to estimate downhole fluid volumes of hydrocarbons such as bitumen, light hydrocarbon, kerogen, and/or water. Having identified the fluid volumes in this manner or any other suitable manner from the NMR measurements, a reservoir producibility index (RPI) may be generated. The downhole fluid volumes and/or the RPI may be output on a well log to enable an operator to make operational and strategic decisions for well production.
