摘要： Logging systems and methods that employ nanosensors to obtain spectral measurements downhole. The nanosensors can be dispersed in borehole fluids (including cement slurries) that circulate, diffuse, or get injected in a borehole. Because the nanosensors have diameters on the order of 10 nm to 1000 nm, they readily penetrate into cracks, pores, and other voids where their carrier fluids can reach. The nanosensors transport light sources and recording media to measure spectra in these otherwise inaccessible regions. The nanosensors are then recovered and analyzed to reconstruct the measured spectra and determine relevant material characteristics. Among other things, spectral measurements can reveal the presence of certain elements and molecules in the formation and fluids, from which information scientists determine composition and phases of formation fluids and the formation itself. Certain triggering criteria may also be employed to enable the nanosensor measurements to be associated with specific locations, paths, and/or events.

摘要： A radiation detection apparatus can include a scintillator, a photosensor optically coupled to the scintillator, and a control module electrically coupled to the photosensor. The control module can be configured to receive a pulse from the photosensor and identify a cause of noise corresponding to the pulse. Such information can be useful in determining failure modes and potentially predict future failures of radiation detection apparatuses. In another embodiment, the wavelet discrimination can be used to determine whether or not the pulse corresponds to a scintillation pulse, and potentially to identify a type of radiation or a radiation source. The technique is robust to work over a variety of temperatures, and particularly, at temperatures significantly higher than room temperature.

摘要： A computer system and computer implemented method for automatically identifying a hydrocarbon (such as kerogen, gas, oil) rich zone in a well bore includes obtaining well log data comprising neutron data, density data, radioactivity data, and resistivity data representative of physical characteristics of a formation surrounding the well bore and computing an apparent neutron porosity and an apparent density porosity based on the neutron data and density data. A normalized neutron-density separation is computed based on the computed apparent neutron porosity and the computed apparent density porosity and a baseline of the formation is determined for each data type. Using the computed normalized neutron-density separation, the radioactivity data, the resistivity data, and the determined baselines, the presence or absence of a hydrocarbon rich zone is determined. A quality index may further be derived from the data.

摘要： Apparatus for wellbore logging and method of use are provided for measurement of the annular materials interposed between the logging tool and formation and the apparent formation bulk density in open-hole, cased-hole or other conduit. The logging tool can be centralized in the borehole. Non-collimated gamma radiation is emitted into the surrounding media and the amount of radiation which returns to the tool is measured by multiple omni-directional detectors spaced a pre-set distances from the source to provide multiple radial depths of investigation. The annular thickness and density of materials interposed between the logging tool and the formation may be determined from the detector responses and be used to derive the apparent formation bulk density.

摘要： A method for determining rock and fluid properties of a fluid-containing subsurface geological formation is provided. First, a low resolution model of the geological formation is initially created from a lumped average parameter estimation derived from at least fluid pressure transient data obtained along a linear wellbore that traverses the formation. Next, the model parameters are updated using grid-based parameter estimation in which the low resolution pressure transient data are combined with data from at least one of seismic data, formation logs, and basic geological structural information surrounding the linear wellbore. Depending on the data available, this process may be carried out in a sequential manner by obtaining and combining additional dynamic data at selected areas. Through this process, multiple realizations of the properties of the geological formation (within the geological structural model) may be created based from the pressure-data conditioned geostatistics i.e. geostatistics that have been informed by data from both static and dynamic sources. Finally, the dynamic simulation of models should be compared to the results of the lumped average parameter estimation to provide a final calibration of the created models.
