  • Patent number: 11099072
    Abstract: Embodiments are disclosed for terahertz spectroscopy and imaging in dynamic environments. In an embodiment, a method comprises emitting a continuous electromagnetic (EM) wave in a terahertz (THz) frequency band into a dynamic environment. The EM THz wave is reflected off an object in the environment. A spectral response of a received signal indicative of the reflected EM wave is determined that includes absorption spectra at a frequency in the THz frequency band. The absorption spectra is indicative of a transmission medium in the environment. The spectral response of the received signal is compensated for fixed and frequency-specific losses. The compensated absorption spectra is compared with known absorption spectra of target transmission mediums. Based on results of the comparing, a particular target transmission medium is identified as being the transmission medium in the environment. The absorption spectra loss is used to determine a concentration level of the target transmission medium.

  • Patent number: 11082127
    Abstract: The ability to communicate with a specific subject at a prescribed location who lacks any communications equipment opens up many intriguing possibilities. Communications across noisy rooms, hail and warn applications, and localized communications directed at only the intended recipient are a few possibilities. We disclose and show localized acoustic communications, which we call photoacoustic communications, with a listener at long standoff distances using a modulated laser transmitted toward the receiver's ear. The optically encoded information is converted into acoustic messages via the photoacoustic effect. The photoacoustic conversion of the optical information into an audible signal occurs via the absorption of the light by ambient water vapor in the near area of the receiver's ear followed by airborne acoustic transmission to the ear. The recipient requires no external communications equipment to receive audible messages.

  • Patent number: 10228706
    Abstract: The present invention provides techniques for recovering hydrocarbon fluids in a process flow, including recovering bitumen from a coarse tailings line. The apparatus includes a signal processor that responds to signaling containing information about the presence of a hydrocarbon fluid in a process flow; and determines corresponding signaling to control the diversion of the hydrocarbon fluid from the process flow remaining based on the signaling received. The hydrocarbon fluid may be bitumen, including bitumen flowing in a course tailings line. The signal processor receives the signaling from a velocity profile meter having sensors arranged around a circumference of a process pipe containing information about a fluid flow velocity at various levels or heights within the process pipe, including a wrap-around velocity profile meter having multiple sensing arrays located radially at a top position of 0° , a bottom position of 180°, and intermediate positions 45°, 90° and 135°.

  • Patent number: 10215690
    Abstract: A method for estimating a value of a kerogen property in a subsurface formation where the value of the kerogen property is unknown. The method includes: measuring spectral intensity values over an infrared (IR) spectral range for a selected sample from the subsurface formation; determining a range of values representing the measured spectral intensity values corresponding to a vibrational mode attributable to kerogen in the selected sample, the range of values including values representing uncertainty in the measured spectral intensity over the portion of the spectral range; and inputting values from the range of values into a stochastic or simple regression model to determine an estimated value of the kerogen property in the selected sample.

  • Patent number: 10175218
    Abstract: This description relates to a predictive model for estimating the proportions of sand, silt, and clay in a soil sample based on near-infrared spectroscopy (NIRS) performed on the soil samples. The soil texture prediction model is trained using benchmark NIRS test data and collected spectra of soil samples for which the benchmark test data has been collected. The estimates produced by the model can be used to determinate a variety of properties of the soil sample, such as hydrological properties and soil quality. Knowledge of these properties are useful for informing decisions that agronomists, producers, or farm managers make throughout the year. For example, agronomists use the determined properties to infer how the soil will perform under any given treatment or application, for example applying seeds, fertilizer, pesticide, and herbicide.

  • Patent number: 10073042
    Abstract: A method and apparatus are provided for performing in-situ fluid analysis. The method involves obtaining a first and second mixture of uncontaminated oil and a contaminant, wherein a percentage of the uncontaminated oil in the first mixture is different from the second mixture. The method may further include establishing a rate of change of a physical property of the first mixture and the second mixture to estimate a mass density of the uncontaminated oil and a mass density of the contaminant. In addition, the method may include obtaining a volume fraction of the uncontaminated oil for the first mixture and second mixture using the mass density of the uncontaminated oil and the mass density of the contaminant. An optical device may be used to determine a composition of the first and second mixtures in order to calculate a composition of the contaminant and a composition of the uncontaminated oil.

  • Patent number: 10012633
    Abstract: Methods are provided for reservoir analysis. In some embodiments, a reservoir may be analyzed by obtaining abundance ratios at a first measurement station and a second measurement station and determining an abundance ratio trend. Abundance ratios at a third measurement station may be obtained and plotted versus depth with the previously obtained abundance ratios. A change in the abundance ratio trend may be identified and result in further investigation of the reservoir. If the abundance ratio is unchanged, additional abundance ratios may be obtained and plotted versus depth to further evaluate the abundance ratio trend. Methods for reservoir analysis using fluid predictions with and without offset well information are also provided.

    Abstract: A method of analyzing a core sample from a wellbore by creating a visual composite image of the core sample that is based on a scan of the core sample. The scan directs radiation at the core sample, such as a computerized tomography (CT) scan, and obtains scan data by estimating radiation absorbed by material in the core sample. The composite image is made up of an arrangement of voxels, where each voxel represents a designated volume of the core sample, and is are assigned a value that corresponds to a measured value of radiation absorbed in the designated volume of the core sample.

  • Patent number: 9784882
    Abstract: A method is disclosed for generating an areal map of a pre-determined hydrocarbon liquid property of a subsurface kerogen-containing source rock from an electromagnetic resistivity profile. Preferably, the profile is generated by a transient EM method such as a long-offset transient electromagnetic (LOTEM) method. In some embodiments, the areal map is generated by employing resistivity-hydrocarbon liquid-quality relationship data describing a relationship between (i) a property of hydrocarbon liquid generated within the source rock pore space to (ii) an electrical resistivity of the source rock. In some embodiments, it is possible to acquire such data even in the absence of source rock samples where the hydrocarbon liquids within the samples has been preserved. The areal map is useful for determining a target location and/or depth in the source rock to drill for oil. The presently-disclosed techniques are particularly relevant to tight oil formations.
