Abstract: Methods and systems for seismic data acquisition in a survey area use compressed sensing and take into consideration operational limitations. The operational limitations may be related to the equipment used for the survey, the topography of the surveyed area or limitations that otherwise optimize the survey path.

Abstract: Seismic data is deblended by performing, for each receiver, a first inversion and a second inversion in a transform domain. The first inversion is formulated to minimize a number of non-zero coefficients of the first inversion result. A sub-domain of the transform domain is defined by vectors of a transform domain basis for which the first inversion has yielded the non-zero coefficients. The second inversion is performed in this sub-domain. The solution of the second inversion is used to extract deblended seismic datasets corresponding to each of the distinct signals, from the seismic data.

Abstract: A system and method for improved coupling of geophysical sensors is disclosed. The method includes determining conditions at an installation location, and selecting a sensor assembly. The sensor assembly includes a threaded device having a shaft with a foot and a head. The threaded device has a cavity that is open at the foot and extends inside the shaft from the foot to the head. The sensor assembly further includes a baseplate configured to couple to the threaded device. The method also includes preparing the installation location for installation of the selected sensor assembly and installing the selected sensor assembly at the installation location.

Abstract: A system and method for coupling geophysical sensors is provided. A method for deploying a geophysical sensor includes treating an installation location with a soil stabilizing material. The method also includes pressing a die (906) into the installation location and after a predetermined time period, removing the die from the installation location. The method further includes installing a geophysical sensor in the installation location.

Abstract: A method for performing a seismic survey using at least one carrier which includes a seismic source. The method includes: deploying each of the at least one carriers by the delivery vehicle, wherein each of the at least one carriers includes: a plurality of supports configured to enable a baseplate to contact ground, wherein the baseplate is formed by each foot of the plurality of supports; a seismic source which includes a lower portion configured to push through unconsolidated materials and configured to contact the ground; and a power source configured to operate the seismic source; and transmitting at least one seismic signal from the seismic source.
