Methods of formulating conductive wellbore fluids
8 Mar 22
A method of formulating an oil-based wellbore fluid, the method comprising adding at least a plurality of conductive carbon black agglomerates or pellets having an average size of at least 500 μm to an oleaginous base fluid, and applying energy to the oil-based wellbore fluid to disperse the plurality of conductive carbon black agglomerates or pellets into the oleaginous base fluid as finer particles than the agglomerates or pellets.

Method for removing the effect of near surface galvanic distortion in surface to borehole EM measurements
8 Mar 22
A system and method of evaluating and correcting for the effects of a near-surface anomaly on surface-to-borehole (STB) measurement data in a geological halfspace includes transmitting electromagnetic radiation from an EM source located on a ground surface which is positioned over the near-surface anomaly, measuring EM fields at a plurality of remote EM receivers located on the surface at a far distance from the EM source, obtaining vertical STB measurement data downhole, determining an orientation and moment of a secondary source equivalent dipole associated with the near-surface anomaly excited by the radiation transmitted by the EM source based on measurements of the EM fields at the plurality of remote receivers, determining a correction factor for the secondary source equivalent dipole on the EM field measurements at the plurality of remote receivers, and removing the effects of the near surface anomaly on the vertical STB measurement data using the correction factor.

Utility
Combining Noise Attenuation and Wavefield Reconstruction In Seismic Processing
3 Mar 22
A method for processing seismic data includes receiving seismic data comprising seismic traces collected from a land-based or marine seismic array, applying a noise mitigation process to the seismic data to generate a first stack volume, identifying, using a machine-learning algorithm, one or more traces of the seismic traces as having a relatively high residual noise, after applying the noise mitigation process, in comparison to other traces of the seismic traces, mitigating noise in the one or more identified traces, and performing a wavefield reconstruction to generate a second stack volume after mitigating the noise in the one or more traces after mitigating the noise in the one or more identified traces, to interpolate a portion of the wavefield corresponding to where the one or more identified traces were located and mitigated.
