20130028051 | FIELD CORRELATION FOR REAL-TIME PASSIVE SEISMIC SURVEILLANCE - There is provided herein a method of passive seismic acquisition that utilizes real time or near real time computation to reduce the volume of data that must be moved from the field to the processing center. Much of the computation that is traditionally applied to passive source data can be done in a streaming fashion. The raw data that passes through a field system can be processed in manageable pieces, after which the original data can be discarded and the intermediate results accumulated and periodically saved. These saved intermediate results are at least two, more likely three, orders of magnitude smaller than the raw data they are derived from. Such a volume of data is trivial to store, transport or transmit, allowing passive seismic acquisition to be practically used for continuous near-real-time seismic surveillance. | 01-31-2013 |

If the marine seismic source has a ratio of signal bandwidth to maximum frequency that is less than one half, then it is possible to deploy it at a greater depth at which ghost notches fall below and above its frequency band but not in it. Further, by placing two or more sources at different depths for the same frequency, any undesired nulls in the radiation pattern caused by the deeper tow can be filled in. | 08-28-2014 |
20150092517 | SYSTEM AND METHOD FOR PERFORMING SEISMIC SURVEYS WITH A CONTROLLED SOURCE USING MAXIMUM-POWER SWEEPS - The output spectrum of a controllable swept-frequency acoustic source at a given frequency can be controlled by making the rate of change of frequency equal to the desired output power spectrum divided by the squared envelope amplitude of the source output signal, both measured at the time after the start of its frequency sweep at which the sweep frequency passes through the given frequency. The system and method can also be used to correct for propagation effects outside the source by dividing the desired spectrum by the propagation effect. The method can further be used either to obtain an output spectrum of a desired shape from a source operating at maximum output or to design a sweep of a minimum feasible duration that will result in an output spectrum of a specified shape and with a specified amplitude. | 04-02-2015 |
20150204992 | Operational Control in a Seismic Source - A method for controlling trajectory in a resonant marine seismic source comprises: controlling the source frequency and controlling the motion trajectory.

Controlling the motion trajectory includes: detecting a motion trajectory of the source; deriving a motion trajectory error as the difference between the desired motion trajectory and detected motion trajectory; and driving the motion trajectory error to zero. | 07-23-2015 |
20150234062 | COMPACT SEISMIC SOURCE FOR LOW FREQUENCY, HUMMING SEISMIC ACQUISITION - A compact seismic source for seismic acquisition generating a humming signal includes a casing and a low-frequency reciprocating drive. The casing defines a fluid tight chamber and comprises a first casing section and a second casing section of roughly equal mass. The drive is disposed within the fluid tight chamber and, in operation, reinforces the natural reciprocating oscillation of the first and second casing sections relative to one another at a low seismic frequency. In one aspect, this action omni-directionally radiates the low frequency, humming seismic signal. On another aspect, the compact seismic source is substantially smaller than the wavelength of the low seismic frequency. Such a compact source may be deployed to omni-directionally radiate a low frequency, humming seismic signal during a seismic survey. | 08-20-2015 |
20150301205 | System and Method for Resonator Frequency Control by Active Feedback - There is taught herein a system and method for creating an improved seismic source signal by applying a feedback mechanism, active adaptive control, to perturb a resonator device configuration on the fly so as to ensure that the overall trajectory of the sweep is correctly produced, even though the precise details of each oscillation of the source are still not constrained. An embodiment teaches a method for adjusting the squeeze piston or tow depth of a resonant piston seismic source to bring the resonant frequency to a desired value. As a consequence, the resulting seismic signal is improved as compared with seismic signals acquired via resonators that do not utilize the instant teachings. | 10-22-2015 |
