20130294194 | METHOD AND APPARATUS FOR SEA CURRENT AIDED, ENHANCED AZIMUTH SEISMIC DATA ACQUISITION - A system of designing and acquiring 3D marine seismic surveys such that the prevailing sea current is parallel or orthogonal to a major axis of the area to be surveyed. By steering the vessel and towed seismic source and receiver arrays through the water, heading into the sea current at some significant angle away from the sea current direction, then the resultant movement of the seismic source and receiver arrays will result in a much richer sampling and measurement of the earth's sub-surface by virtue of increasing the range of source-to-receiver azimuths available. By adopting this method, the final 3D seismic image of the subsurface will be more accurate and will be correctly focussed. Also line change times may be reduced significantly and the overall carbon footprint of the seismic survey may be lessened. | 11-07-2013 |
20130003497 | STREAMER CABLE FOR USE IN MARINE SEISMIC EXPLORATION AND METHOD FOR REDUCING NOISE GENERATION IN MARINE SEISMIC EXPLORATION - The present invention relates to a streamer cable for use in marine seismic exploration. Further, a method for reducing noise generation in marine seismic exploration is described, as well as a method for the preparation of the said seismic cables. | 01-03-2013 |
20120067368 | APPARATUS FOR IN-SITU CLEANING OF A SEISMIC STREAMER CABLE - A system, method and apparatus providing uninterrupted cleaning of first and second parts of a deployed marine seismic streamer cable using one cleaner apparatus, the first and second parts located to respective sides of a bird attached to the streamer cable. The system comprises a connecting apparatus for connecting by a web or rung the bird to the streamer cable, and the cleaner apparatus provided with a slit open over the full length of the cleaner and adapted to let the web or rung pass from end to end of the cleaner, whereby the cleaner is allowed to pass from the first part to the second part without interrupting its cleaning action. | 03-22-2012 |
