  • Publication number: 20210373189
    Abstract: In addition to drilling operations a hard rock drill rig is used to induce seismic energy into subsurface rock formations. In quartz rich rock the seismic energy will partially convert to electrical energy thereby allowing for the prospecting of ore-bearing quartz veins. Seismic energy and electric energy are detected by a sensor array. The electric energy is used to infer the presence of piezoelectric materials in the rock formations, and such materials are mapped using the detected seismic energy and electric energy.

  • Patent number: 11150375
    Abstract: An electromagnetic (EM) data acquisition method for a geological formation may include operating EM measurement devices to determine phase and amplitude data from the geological formation. The EM measurement devices may include at least one first EM measurement device within a borehole in the geological formation, and at least one second EM measurement device at a surface of the geological formation. The method may further include processing the phase data independent from the amplitude data to generate a geological constituent map of the geological formation, and identifying different geological constituents in the geological constituent map based upon the measured amplitude data.

  • Patent number: 10401528
    Abstract: In one embodiment, a method includes receiving one or more datasets including measured vertical electric and magnetic fields excited by one or more radial and azimuthal electric field antennas from a downtool into one or more processors, wherein each of the one or more datasets corresponds to a different position of the one or more radial azimuthal electric field antennas, simultaneously inverting the one or more datasets using the one or more processors, and as a result of the simultaneous inversion, generating by the one or more processors a three-dimensional (3D) image of a portion of the geological formation.

  • Patent number: 10386531
    Abstract: A method for geological formation analysis may include collecting time-lapsed well-based measurement data from a first borehole in a geological formation over a measurement time period, and collecting time-lapsed electromagnetic (EM) cross-well measurement data via a plurality of spaced-apart second boreholes in the geological formation over the measurement time period. The method may further include determining simulated changes to a hydrocarbon resource in the geological formation over the measurement time period based upon a geological model using a processor, and using the processor to determine if the simulated changes are within an error threshold of the time-lapsed well-based measurement data and the time-lapsed cross-well EM measurement data. If the simulated changes are not within the error threshold, then the geological model may be updated.

  • Patent number: 10379250
    Abstract: An electromagnetic data acquisition system and an associated method for measuring subsurface structures with electromagnetic fields is employed for removing near surface effects from borehole to surface electromagnetic data. Preferably, the system is used to obtain information about deep, target structures located deep below the Earth, especially in oil and gas fields, while mitigating the effect of near surface geological shallow structures on collected electromagnetic (EM) data by using a series of electromagnetic measurements and data treatments that preferentially illuminate near surface geologic shallow structures so that the shallow structures may be recovered separately from deep structures of interest.

  • Patent number: 10371853
    Abstract: A nuclear magnetic resonance (NMR) system that uses a feedback induction coil to detect NMR signals generated within a substance is described herein. In one embodiment, the NMR system uses the Earth's magnetic field in conjunction with a transmitter coil that applies NMR sequences to a formation. The NMR sequences generate a weak NMR signal within the formation due to the weakness of the Earth's magnetic field. This weak NMR signal is detected using the feedback induction coil.

  • Patent number: 10365394
    Abstract: An electromagnetic geophysical survey is performed by transmitting current from a first source into earth, the first source being located in a borehole. An electromagnetic field generated by the current transmitted from the first source is measured to create subsurface data. In addition, a background model is constructed and a leakage current distribution is calculated. A resistivity distribution of the earth is calculated using the subsurface data, the background model and the leakage current distribution, with the leakage current distribution being used as a source current distribution.

  • Publication number: 20190219724
    Abstract: The integrity of a well is evaluated using a non-invasive and lower cost screening system and method. The system and method identify whether well integrity has degraded and whether there is a clear break in the casing of a well, a corroded patch or faults in the casing. This is accomplished without requiring entry into the well.

  • Patent number: 10209388
    Abstract: Systems, methods, and apparatuses to generate a crosswell data set are described. In certain aspects, a method includes producing a first electromagnetic field at the earth's surface with a transmitter at a first location, detecting in a first borehole a first field signal induced by the first electromagnetic field, detecting in a second borehole a second field signal induced by the first electromagnetic field, and generating a crosswell data set from the first field signal and the second field signal. A formation model may be created from the crosswell data set.

  • Patent number: 10024995
    Abstract: Methods and systems are provided to determine a property of an earth formation, comprising a mobile transmitter disposed at a predetermined elevated height above a surface of the earth formation, and one or more receivers moveably disposed in a wellbore penetrating the earth formation. Electromagnetic energy is transmitted from the mobile transmitter into the formation from a plurality of locations; and at the one or more receivers a signal is measured. Using the signal received by the one or more receivers, a property of the formation, such as resistivity, can be determined and mapped.
