VIBRATOR SOURCE BASEPLATE ERGONOMIC CONTROL
A remote control system for a vibratory seismic source that generates seismic signals. The remote control system includes an attachment mechanism configured to be fixedly attached to a component of a vehicle carrier that carries the vibratory seismic source, and a remote control mechanism supported by the attachment mechanism, wherein the remote control mechanism includes first and second command units, each configured to control a baseplate associated with the vibratory seismic source. Each of the first and second command units are configured to be removed from the remote control mechanism while the attachment mechanism is hold in place.
IMAGING A SUBTERRANEAN FORMATION THROUGH ACOUSTIC ENERGY DELIVERED THROUGH A LIQUID
Techniques for imaging a subterranean formation include activating an acoustic energy source that is at least partially submerged in a volume of liquid on or under a terranean surface; based on the activating, producing acoustic wave energy that travels through the volume of liquid and to a subterranean zone below the terranean surface; receiving, at one or more acoustic receivers, reflected acoustic wave energy from the subterranean zone; and generating, with a control system, data associated with the subterranean zone based on the reflected acoustic wave energy.

Method and system for selecting parameters of a seismic source array
A method for selecting parameters of a seismic source array comprising a plurality of source elements each having a notional source spectrum is described, the method comprising calculating a ghost response function of the array; calculating directivity effects of the array; and adjusting the parameters of the array such that the directivity effects of the array are compensated by the ghost response to minimize angular variation of a far field response in a predetermined frequency range. A method for determining a phase center of a seismic source array is also related, the method comprising calculating a far field spectrum of the array at predetermined spherical angles, and minimizing the phase difference between the farfield spectra within a predetermined frequency range by adjusting a vertical reference position from which the spherical angles are defined.
