  • Publication number: 20210002999
    Abstract: The present invention belongs to the technical field of oil and gas field development, and discloses a method for calculating a single-well controlled reserve of a low-permeability/tight gas reservoir and analyzing residual gas thereof. The method includes: calculating a reserve controlled by each gas well in a block by using a gas reservoir dynamic reserve calculation method; establishing a new reserve calculation formula for solution and comparative analysis by an example; and quantitatively analyzing an effect of a startup pressure gradient and a stress sensitivity on a calculation result of the single-well controlled reserve, wherein the analysis of the factors affecting reserve calculation shows that, when the startup pressure gradient reaches 0.02 MPa/m, the calculated reserve is significantly reduced compared with a conventional method, but when the startup pressure gradient is greater than 0.1 MPa/m, the effect gradually stabilizes.

  • Patent number: 10648917
    Abstract: In one aspect, methods of sensing are described herein. In some embodiments, a method of sensing includes disposing a fluorophore in a biological environment, wherein the fluorophore includes a dioxo-pyridine ring (DPR) or a thiazolopyridine acid (TPA). The method further includes exposing the biological environment to electromagnetic radiation having a wavelength corresponding to an excitation wavelength of the fluorophore, detecting light emitted by the fluorophore, and correlating the light emitted by the fluorophore to a presence or absence of an analyte within the biological environment in an amount above a minimum detection threshold. The presence of the analyte can increase or decrease the amount of light emitted by the fluorophore. The presence of the analyte may also shift the peak emission wavelength or alter the fluorescence lifetime of the fluorophore. The analyte, in some embodiments, includes hydrogen ions, halide ions, and/or halogens.
