Patent number: 9171206Abstract: Described herein are implementations of various technologies for a method for mapping water table depths. In one implementation, a satellite image of an area of interest may be received. The satellite image may comprise a red spectrum, a green spectrum and a blue spectrum. A first map may be generated that identifies only water features on the satellite image. The first map may be convolved with a digital elevation model of the area of interest to generate a second map. The second map may identify elevations of the water features on the satellite image. An interpolation algorithm may be applied to the second map to generate a third map. The third map may identify water tables and elevations for the water tables on the satellite image.Type: GrantFiled: March 1, 2013Date of Patent: October 27, 2015Assignee: WesternGeco L.L.C.Inventor: Andreas Laake

Patent number: 8537637Abstract: A method of seismic surveying A method of seismic surveying comprises the step of acquiring imaging seismic data relating to an underlying geological structure at a survey location and simultaneously, or substantially simultaneously, acquiring statics seismic data relating to the near-surface (5) at the survey location. The method may use an imaging source (12) to acquire the imaging seismic data and a separate statics source (13,13?) to acquire the statics seismic data. Alternatively only an imaging source (12) may be used, and the statics seismic data may be obtained from surface waves, airwaves or ground-roll waves that are generated by the imaging source and that have hitherto been regarded only as unwanted noise.Type: GrantFiled: December 19, 2002Date of Patent: September 17, 2013Assignee: WesternGeco L.L.C.Inventor: Andreas Laake

Patent number: 8441891Abstract: The present invention relates to producing a quality control measure for use during data acquisition and/or data processing of, preferably, seismic data. While or after obtaining the data, a surface consistent decomposition of the data is performed. From the surface consistent decomposition, one may compute a decomposed logarithmic spectra, and from the decomposed logarithmic spectra, one may compute one or more residua. An error attribute based on the one or more residua can be formulated, analyzed, and output. The error attribute can be used as a quality control measure or the analysis result can be used to produce a quality control measure.Type: GrantFiled: December 30, 2009Date of Patent: May 14, 2013Assignee: WesternGeco L.L.C.Inventors: Ralf Ferber, Franz Kirchheimer, Andreas Laake

Publication number: 20070195645Abstract: A method for generating one or more maps of a survey area. In one implementation, the method may include receiving earth observation data, decomposing the earth observation data into pixels, georeferencing the earth observation data in pixel form with the curvature of the earth's surface, integrating the earth observation data in pixel form with seismic data, extracting one or more attributes from the integrated data and displaying the extracted attributes on one or more survey maps.Type: ApplicationFiled: April 23, 2007Publication date: August 23, 2007Inventor: ANDREAS LAAKE

The apparatus includes a program storage medium encoded with instructions that, when executed by a computing device perform the method and a computer programmed to perform the method.Type: ApplicationFiled: July 25, 2005Publication date: February 8, 2007Inventor: Andreas Laake

Publication number: 20060291329Abstract: A method of processing seismic data comprises processing data representative of the acceleration wavefield so as to obtain information about the earth's subsurface direct from the seismic data representative of the acceleration wavefield. In conventional techniques for processing seismic data representative of the acceleration wavefield the data are transformed to the velocity domain at an early stage in the processing. The invention enables the transform step to be eliminated, thereby simplifying the processing and eliminating the risk that the transform might degrade the data. Furthermore, the increased sensitivity at high frequencies of a typical acceleration sensor compensates for the low-pass filter effect of the earth.Type: ApplicationFiled: March 26, 2004Publication date: December 28, 2006Inventors: James Martin, Andreas Laake

Patent number: 6772068Abstract: A method of monitoring the quality of data is disclosed. The method includes sampling a first acquired data trace to determine the amplitude of the trace at a plurality of sampling times; and determining first and second attributes for the acquired first data trace from the sampled amplitudes of the first acquired data trace, the first and second attributes being indicative of the noise content of the first acquired data trace.Type: GrantFiled: December 13, 2002Date of Patent: August 3, 2004Inventor: Andreas Laake

Publication number: 20030182064Abstract: A method of monitoring the quality of data comprises sampling a data trace to determine the amplitude of the trace. Attributes that are indicative of the noise content of the data trace are then determined from the sampled amplitudes of the first data trace. The noise attributes of a particular data trace can be compared with pre-set threshold values or with the attributes determined for another data trace, thereby providing a method monitoring the quality of the data. The sampling process is performed in the time domain, and requires only a small amount of computation. The quality control can therefore be carried out on-line, so that the quality of the data can be monitored as it is acquired. The method can be applied to the quality control of seismic data.Type: ApplicationFiled: December 13, 2002Publication date: September 25, 2003Inventor: Andreas Laake
