Abstract: Marine seismic survey systems and methods are presented. One system comprises a source array, a tow vessel, one or more source tow members, one or more deflecting members operatively connected to the source array; one or more streamers connected to the tow vessel by a corresponding number of streamer tow members, one or more of the streamers positioned by corresponding one or more active or passive streamer deflectors, one or more source separation members connecting one or more source tow members to one or more streamer tow members, and optionally one or more streamer separation members connecting one or more streamer tow members. The one or more source separation members help position the source array in conjunction with the one or more. deflecting members. This abstract complies with rules requiring an abstract. It should not be used to limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract: A sensor assembly includes a seismic sensor element and a shell. The shell at least partially surrounds the sensor element to shield the sensor element from a magnetic field that is generated outside of the shell.

Abstract: A technique includes providing a pricing scheme to sell at least one seismic data-based product. The seismic data-based product(s) are generated from seismic data that is obtained from at least one sensor in tow, and the seismic data includes particle motion data, which the pricing scheme excludes from being sold.

Abstract: In one embodiment, the invention relates to a method for location, or location and entry, of a lateral wellbore from a main wellbore of a multilateral hydrocarbon well, the method being characterized by unique operation of a controllably bent sub. The invention further relates to a system for location, or location and entry of a lateral wellbore, including a specialized controllably bent sub, and most preferably, to a controllably bent sub designed for efficient lateral wellbore location and/or entry.
