| 20110266086 | Seismic Data Acquisition Using Self-Propelled Underwater Vehicles - The present disclosure generally relates to the use of a self-propelled underwater vehicle for seismic data acquisition. The self-propelled underwater vehicle is adapted to gather seismic data from the seafloor and transmit such data to a control vessel. The self-propelled underwater vehicle may be redeployed to several seafloor locations during a seismic survey. Methods for real-time modeling of a target zone and redeployment of the self-propelled underwater vehicle based on the modeling are also described. | 11-03-2011 |
| 20140202786 | OPTICAL SEISMIC SENSOR SYSTEMS AND METHODS - Disclosed is an optical seismic sensor system for measuring seismic events in a geological formation, including a surface unit for generating and processing an optical signal, and a sensor device optically connected to the surface unit for receiving the optical signal over an optical conduit. The sensor device includes at least one sensor head for sensing a seismic disturbance from at least one direction during a deployment of the sensor device within a borehole of the geological formation. The sensor head includes a frame and a reference mass attached to the frame via at least one flexure, such that movement of the reference mass relative to the frame is constrained to a single predetermined path. | 07-24-2014 |
| 20160097631 | Pressure-Balanced Seismic Sensor Package - Apparatus, systems and methods associated with a pressure-balanced seismic sensor package are disclosed. One example of an apparatus can include a plurality of optical components, a sensor box enclosing the plurality of optical components, and a lid for the sensor box. The plurality of optical components, the sensor box, and the lid form a pressure-balanced seismic sensor package. | 04-07-2016 |

| 20120181103 | System and method for generating and controlling conducted acoustic waves for geophysical exploration - An improved system and method for generating and controlling conducted acoustic waves for geophysical exploration are provided. A plurality of overpressure waves are generated by at least one overpressure wave generator comprising at least one detonation tube having an open end. The at least one overpressure wave generator is oriented so the plurality of overpressure waves are not directed directly towards a target media. The recoil force of the at least one overpressure wave generator occurring during generation of the plurality of overpressure waves is coupled to the target media to generate conducted acoustic waves. The timing of the generation of the plurality of overpressure waves can be in accordance with a timing code and can be used to steer the conducted acoustic waves to a location of interest in the target media. | 07-19-2012 |
| 20120205188 | SYSTEM AND METHOD FOR GENERATING AND CONTROLLING CONDUCTED ACOUSTIC WAVES FOR GEOPHYSICAL EXPLORATION - An improved system and method for generating and controlling conducted acoustic waves for geophysical exploration are provided. A plurality of overpressure waves are generated by at least one overpressure wave generator comprising at least one detonation tube having an open end that may be directed away from, parallel to, or towards a target media. Recoil forces of the at least one overpressure wave generator, produced shear forces, or the forces of the plurality of overpressure waves are coupled to the target media to generate conducted acoustic waves. The timing of the generation of the plurality of overpressure waves can be in accordance with a timing code and can be used to steer the conducted acoustic waves to a location of interest in the target media. | 08-16-2012 |
| 20140034412 | METHOD AND DEVICE FOR DYNAMIC CONTROL OF DELAYS IN GUN CONTROLLER - A method controls a delay of an air-gun in an aquatic seismic source. The method includes a step of receiving an attribute of the air-gun during the aquatic seismic survey; a step of calculating, based on a time-delay algorithm that uses the attribute, the asynchronization time of the air-gun; a step of determining whether the asynchronization time is smaller than a given time threshold; a step of instructing a controller to (1) wait for a predetermined time before calculating again the asynchronization time of the air-gun if the asynchronization time is smaller than the given time threshold, or (2) calculate an updated asynchronization time for the air-gun based on the attribute if the asynchronization time is larger than the given time threshold; and a step of sending the updated asynchronization time to a gun controller of the air-gun for adjusting a delay time for firing the air-gun. | 02-06-2014 |
