摘要： Devices and methods for well logging using a diamond window assembly are provided. A method according to the disclosure includes placing a downhole tool in a wellbore in a geological formation and compressing a window assembly in the downhole tool against the geological formation. The window assembly may include a polycrystalline diamond compound material fused with a monocrystalline diamond window that holds the monocrystalline diamond window in place, despite being compressed against the geological formation. First photonic radiation may be emitted through the monocrystalline diamond window onto the geological formation. Second photonic radiation may be detected through the monocrystalline diamond window. This second photonic radiation may derive from interactions between the first photonic radiation and the geological formation. As such, the second photonic radiation may carry information relating to the composition of the geological formation (e.g., the presence or absence of hydrocarbons).

摘要： Delivery of a substance to a subterranean location is achieved by suspending the substance as nanoparticles in a carrier fluid in which the substance is insoluble. The procedure may start by forming a dispersible powder composition, which is done by dissolving the substance in a solvent, emulsifying the resulting solution as the dispersed phase of an emulsion, and freeze- drying the emulsion to a powder. On mixing the powder with a fluid in which the substance is insoluble, any soluble constituents of the powder dissolve and the insoluble substance becomes a dispersion of nanoparticles of the substance. Then, the fluid containing the dispersed substance is pumped to the subterranean location. The dispersion of nanoparticles has surprising stability, facilitating transport to the subterranean location. At the subterranean location the dispersed nanoparticles may migrate into other fluid encountered there: more specifically a dispersed tracer substance may migrate from injected water into hydrocarbon in a hydrocarbon reservoir. Another possibility is that dispersion as nanoparticles enables interaction with other constituents of the fluid to be delayed until the subterranean location is reached: more specifically the fluid may contain polymer and the dispersed nanoparticles may comprise an agent which participates in cross-linking and consequent viscosification of the polymer.

摘要： An improved manufacturing process for resonator-based pressure transducers is described. The process is a batch process in which several resonators are shaped simultaneously, using an etching process such as plasma etching. The end pieces are also shaped, if required, for several transducers. The end pieces and resonators are sandwiched together prior to separating the individual transducer units. The individual transducer units are then separated using a cutting process. The described process can be used to manufacture pressure transducers having a substantially smaller size, for example 5-6 mm outer dimensions and 2-3mm resonators. The outer shape of the transducers can be a non-circular cylindrical shape such as that of a right square prism or an octagonal prism.
