Well Logging Patents (Class 367/25)
  • Patent number: 11550079
    Abstract: The present disclosure is directed to numerically estimating the shear modulus of Kerogen by using a combination of mineralogy from digital image analysis and sonic log analysis, when measured data on only one elastic constant (Bulk, Young's or P-wave modulus) is available. In some instances, elastic properties predicted from the digital images are compared with sonic, shear, and density logs, to estimate the shear modulus of kerogen. As a one-to-one correspondence is not expected between the core sub-samples and the rock unit sampled by the well logs, cross-property relations can be used to identify the suitability of the effective medium models and to iteratively determine the shear modulus of kerogen.

  • Patent number: 11428834
    Abstract: This disclosure describes processes and systems for generating a high-resolution velocity model of a subterranean formation from recorded seismic data gathers obtained in a marine seismic survey of the subterranean formation. A velocity model is computed by iterative FWI using reflections, resolving the velocity field of deep subterranean targets without requiring ultralong offsets. The processes and systems use of an impedance sensitivity kernel to characterize reflections in a modeled wavefield, and then use the reflections to compute a velocity sensitivity kernel that is used to produce low-wavenumber updates to the velocity model. The iterative process is applied in a cascade such that position of reflectors and background velocity are simultaneously updated. Once the low-wavenumber components of the velocity model are updated, the velocity model is used as an input of conventional FWI to introduce missing velocity components (i.e., high-wavenumber) to increase the resolution of the velocity model.

  • Patent number: 11366243
    Abstract: Disclosed is a system and method for improving the performance of downhole Distributed Acoustic Sensing (DAS) systems by simultaneous use of co-propagating and counter-propagating Distributed Raman Amplification (DRA). It uses a surface DRA system with a surface DAS system to combine their laser sources where the distal end of the downhole sensing fiber use uses a Wavelength Division Multiplexer (WDM) to optically split the DRA and DAS signals onto two optical fibers. The DAS fiber/signal is terminated with a low reflectance termination to minimize a potential back reflection whereas the DRA fiber is terminated with a high reflectance termination causing all the light to reflect back up the sensing fiber. This arrangement allows for simultaneous co and counter-propagating DRA of the DAS signals, both the transmitted pulse and the back scattered light, thus creating the maximum amount of gain possible.

  • Patent number: 10301935
    Abstract: Hybrid inversion processing techniques are implemented that result in improved speed and accuracy of determining formation properties using log data, for example, from an multi-component induction logging tool. Logging data relating to the formation of interest is obtained and used as an input. High frequency noise is then removed from the logging data and bed-boundary determination is performed using the logging data. An adaptive low pass filter is applied to the logging data and the logging data is inverted. The inverted logging data is correct and enhanced by determining one or more weights based on one or more quality indicators. The inverted logging data may then be visually interpreted and used to adjust one or more drilling parameters.

  • Patent number: 10295691
    Abstract: To process geological log data, a two-dimensional set of log values recorded at a plurality of points is obtained about a borehole periphery, and over a chosen length along the borehole. The set of log values are decomposed by identifying in the set one or more main functions indicative of one or more main geological layer features of the rock penetrated by the borehole and removing log values corresponding to values of the main functions from the set of log values. Further decomposing the set of log values can be performed, as necessary iteratively, based on one or more subsidiary functions. The log values of the set remaining after identification and removal of values are designated as texture. Functions indicative of the main and subsidiary layer features and the texture are used to construct a synthesized volume representing the rock removed during creation of the chosen length of the borehole.

  • Patent number: 10267140
    Abstract: Fracture imaging modules having one or more 3-component sensors, are incorporated into a tool comprising two or more of the modules for detecting microseismic events in a formation from the same wellbore as is being stimulated. The modules are locked together in a compact mode to permit injection into the wellbore through a conventional lubricator which has a fixed length. Once injected into the wellbore, the modules are spaced from one another in an extended mode to form an axially spaced sensor array which increases the measurement window in the wellbore compared to sensor arrays conventionally injected through a fixed length lubricator. Following the operation, the modules are actuated to return to the compact mode for pulling out of the hole through the lubricator.

  • Patent number: 10120343
    Abstract: The invention relates to a method, system and apparatus for synchronizing the time of time series data acquired from a wellbore sensor relative to a reference time series. This comprises acquiring a first time series from a sensor in a wellbore, acquiring a reference time series and determining a linear moveout time correction to apply to the first time series. The linear moveout time correction is equal to the depth of the wellbore sensor divided by the signal propagation velocity. The linear moveout correction is applied to the first time series. The first time series is cross-correlated with the reference time series to determine a cross-correlation time correction to apply to the first time series and the cross-correlation time correction is applied to the first time series to obtain a cross-correlation corrected time series. Dynamic time warping and dynamic cross-correlation may be used to adjust for clock drift.
