Publication number: 20190195067Abstract: In some implementations, airborne electromagnetic (AEM) data and seismic data for a geographic region including sand dunes are received, and the AEM data identifies apparent resistivity as a function of depth within the sand dunes. An inversion with cross-domain regularization is calculated of the AEM data and the seismic data to generate a velocity-depth model, and the velocity depth model identifies velocity variations within the sand dunes. A seismic image using the velocity-depth model is generated.Type: ApplicationFiled: December 26, 2017Publication date: June 27, 2019Inventors: Daniele Colombo, Gary W.

Patent number: 10296679Abstract: The invention is a method for exploitation of a sedimentary basin containing hydrocarbons using basin simulation. Based on a reconstitution of the formation of the first of the layers of the basin, a conjoint basin simulations of at least one of the layers underlying the first layer. A conjoint geomechanical simulation of the first layer and the at least one underlying layer is then carried out. If the deviation between some of at least some parameters from the geomechanical simulation and those from the basin simulation is above a predefined threshold, the previous steps are repeated applying a correction to the basin simulation. The basin is then exploited as a function of the results of the basin simulation.

Publication number: 20190011587Abstract: Seismic data from seismic exploration surveys are mapped into a hypercube of bins or voxels in a four-dimensional space (X, Y, Offset, and Azimuth) according to Common Mid-Point (or CMP) between source and receivers. The mapped data from individual voxels or bins is then analyzed by multimodal statistics. Robust estimates of first break picks are obtained from the analysis. The first break picks are then used to as seed inputs for autopicking iteration, which proceeds to convergence. Estimates of confidence levels in the data are provided for re-picking to reduce computer processing time in successive autopicking iterations. Analysis is provided of different seismic attributes such as azimuthal velocity variations indicative of anisotropy, positioning errors of sources/receivers, geometry errors, and three dimensional distribution of inversion residuals. Analysis is also performed of standard deviation of the travel time data useful for estimating data errors in the inversion covariance matrix.Type: ApplicationFiled: August 31, 2018Publication date: January 10, 2019Inventors: DANIELE COLOMBO, FEDERICO MIORELLI, DIEGO ROVETTA, GARY WAYNE MCNEICE

Publication number: 20180329103Abstract: Naturally-occurring, electromagnetic signals generated by interaction of solar wind with earth's magnetosphere adjacent a borehole are measured by an electromagnetic sensor positioned adjacent the borehole in the hydrocarbon-bearing formation. Electromagnetic signals generated within the borehole are measured over a period of time by a borehole sensor positioned within the borehole. The electromagnetic signals change over the period of time due to variations in fluid distributions within the hydrocarbon-bearing formation. Electromagnetic changes to the electromagnetic signals generated within the borehole and to the passive, naturally-occurring electromagnetic signals over the period of time are determined by one or more processors. A computational model of the hydrocarbon-bearing formation is generated based in part on the electromagnetic changes.Type: ApplicationFiled: May 9, 2018Publication date: November 15, 2018Applicant: Saudi Arabian Oil CompanyInventors: Daniele Colombo, Gary W.

Publication number: 20170176617Abstract: A surface-consistent refraction analysis method to automatically derive near surface corrections for seismic data processing. The method uses concepts from surface-consistent analysis applied to refracted arrivals. The method includes the use of CMP-offset-azimuth binning, evaluation of mean travel time and standard deviation for each bin, rejection of anomalous first break (FB) picks, derivation of CMP-based travel time-offset functions, conversion to velocity-depth functions, evaluation of long wavelength statics and calculation of surface-consistent residual statics through waveform cross-correlation. Residual time lags are evaluated in multiple CMP-offset-azimuth bins by similarity analysis with a pilot trace for all the other traces in the gather where the correlation window is centered at the refracted arrival. The similarity analysis may take the form of computerized cross-correlation, or other criteria such as semblance.Type: ApplicationFiled: November 28, 2016Publication date: June 22, 2017Inventors: Daniele Colombo, Federico Mlorelli

Patent number: 7805250Abstract: Methods and apparatus are provided for generating velocity models for pre-stack depth migration (“PSDM”). Seismic, gravity and electromagnetic joint inversion input data are generated based on observed seismic, gravity and electromagnetic data (e.g., magnetotelluric and/or controlled source electromagnetic), and velocity, density and resistivity models. A joint inversion is performed to produce a multiparametric model that is a function of velocity, density and resistivity parameter distributions. The separate parameter distributions are extracted from the multiparametric model, and the extracted velocity model is used to perform a PSDM. A migration velocity analysis is performed on PSDM output to generate seismic image residuals. If the seismic image residuals meet predetermined quality objectives, the extracted velocity model is output as the final velocity model for PSDM.Type: GrantFiled: July 27, 2007Date of Patent: September 28, 2010Assignee: WesternGeco L.L.C.Inventors: Daniele Colombo, Michele De Stefano
