  • Patent number: 11215720
    Abstract: Methods and apparatuses for processing seismic data acquired with multicomponent sensors build an accurate S-wave velocity model of a surveyed underground formation using a full waveform inversion (FWI) approach. PS synthetic data is generated using approximative acoustic equations in anisotropic media with a P-wave model, a current S-wave velocity model and a reflectivity model as inputs. The current S-wave velocity model is updated using FWI to minimize an amplitude-discrepancy-mitigating cost function that alleviates the amplitude mismatch between the PS observed data and the PS synthetic data due to the use of the approximative acoustic equations.

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.

A combination sensor is operated and deployed in a borehole to obtain orientation data, such as data related to the local magnetic field and a log of the magnetic field direction in the borehole. Following the combination sensor, at least one multi-component seismic source is deployed downhole into the borehole. The at least one multi-component seismic source comprises sensors, such as an inclinometer and a magnetometer. Data from the combination sensor and from the at least one multi-component seismic source is processed to determine an absolute orientation of the at least one multi-component seismic source.

  • Patent number: 10168442
    Abstract: Systems and methods for differential energy analysis of dipole acoustic signals to facilitate identification of geological or borehole characteristics are provided. An acoustic downhole tool may be placed into a borehole in a geological formation. A dipole acoustic signal may be emitted using one or more acoustic transmitters of the downhole tool, and the dipole acoustic signal may be measured using one or more acoustic receivers of the downhole tool. Using a processor, a dipole differential energy of the dipole acoustic signal (as measured by two of the one or more acoustic receivers or as emitted by two of the one or more acoustic transmitters, or both) may be computed. The processor may provide an indication of the dipole differential energy to facilitate identification of characteristics of the geological formation or the borehole, or both.

  • 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.

  • Patent number: 10113902
    Abstract: A fiber optic distributed vibration system for detecting seismic signals in an earth formation is provided. The system includes a fiber optic cable deployed in a borehole that extends into the earth formation and which is configured to react along its length to a seismic wave incident on the fiber optic cable from outside the borehole. An optical source launches an optical signal into the fiber optic cable while the seismic wave is incident thereon. A receiver detects coherent Rayleigh noise (CRN) produced in response to the optical signal. A processing circuit processes the detected CRN signal to determine characteristics of the earth formation.

  • Patent number: 9842581
    Abstract: A transmitter for an acoustic logging tool includes an elongated housing, an acoustic energy generator, and a driver. The elongate housing defines a hollow interior and supports an acoustic energy generator, which includes four mutually orthogonally orientated bender bars that are electrically driveable to flex within the hollow interior in order to generate pressure-derived waves in a fluid surrounding the transmitter in use. The housing includes one or more transmissive windows via which flexing of the bender bars gives rise to propagation of one or more said waves in a said fluid. The driver electrically drives the bender bars to flex so as selectively to generate monopole, dipole, or quadrupole waves in a said fluid, with the poles of the dipole and quadrupole when generated selectively being aligned with normals to pairs of the bender bars or rotated 45° relative thereto.
