Abstract: A method for seismic surveying comprises deploying a plurality of seismic receivers proximate an area of subsurface to be surveyed. At least one seismic energy source moves in a path that circumscribes a center, wherein positions of the plurality of seismic receivers remain fixed. At least one of a distance between the path and the center changes monotonically as seismic energy source traverses the path, or the center moves in a selected direction as the seismic energy source traverses the path. The source is actuated at selected times as the at least one seismic energy source traverses the path, such that a spacing between positions of the source along the source path and transverse to the source path varies between successive actuations of the source. Seismic energy is detected at the plurality of seismic receivers resulting from actuating the at least one seismic energy source.

Abstract: An air gun for generating seismic waves in a marine environment includes a cylindrical body configured to hold compressed air and having plural air ports for releasing the compressed air from inside the cylindrical body, the cylindrical body extending along a longitudinal axis X, and an extension member attached externally to the body and extending along a radial axis R, which is perpendicular to the longitudinal axis X. The extension member promotes ambient water flowing inside an air bubble generated when the compressed air is released outside the body.

Abstract: A marine vibrator may include a containment housing, a sound radiating surface, and a compliance chamber. The compliance chamber may include a compliance chamber housing, a non-linear linkage assembly, and a low pressure chamber. The compliance chamber housing may define at least a portion of a compliance chamber internal volume having a compliance chamber internal gas pressure. The low pressure chamber may comprise a low pressure piston and a low pressure chamber housing. The low pressure chamber housing may define at least a portion of a low pressure chamber internal volume having a low pressure chamber internal gas pressure. The low pressure piston may be configured to move in response to a pressure differential across the low pressure piston such that a resonance frequency of the marine vibrator may be changed.

Abstract: A method for 2D seismic data acquisition includes determining source-point seismic survey positions for a combined deep profile seismic data acquisition with a shallow profile seismic data acquisition wherein the source-point positions are based on non-uniform optimal sampling. A seismic data set is acquired with a first set of air-guns optimized for a deep-data seismic profile and the data set is acquired with a second set of air-guns optimized for a shallow-data seismic profile. The data are de-blended to obtain a deep 2D seismic dataset and a shallow 2D seismic dataset.

Abstract: A seal and seal assembly for a fluid pressure pulse generating tool. The seal comprises an annular seal section comprising an internal sealing surface and an external sealing surface; and an annular heel section. The seal assembly comprises a seal assembly housing with a longitudinally extending bore therethrough for receiving a driveshaft of the tool and the seal enclosed by the seal assembly housing and configured to surround a portion of the driveshaft. The internal sealing surface of the seal is configured to be in sealing contact with the driveshaft and the external sealing surface of the seal is configured to be in sealing contact with an internal surface of the seal assembly housing. The annular heel section of the seal is configured to provide an interference fit with the driveshaft or with the internal surface of the seal assembly housing.

Abstract: An example system includes a first seismic source configured to emit seismic energy by generation of a first air bubble into the seismic medium at a first time, and a second seismic source spaced a predefined distance from the first seismic source. The second seismic source is configured to emit seismic energy by generation of a second air bubble into the seismic medium at a second time after the first time. The seismic energy has a low frequency characteristic.

Abstract: Hydraulic pulses are produced each time that a pulse valve interrupts the flow of a pressurized fluid through a conduit. The pulse valve includes an elongate housing having an inlet configured to couple to the conduit to receive the pressurized fluid, and an outlet configured to couple to one or more tools. In the housing, a valve assembly includes a poppet reciprocating between open and closed positions, and a poppet seat, in which the poppet closes to partially block the flow of pressurized fluid through the valve. A bypass passage is configured to connect with a valve actuation vent port such that when the poppet closes the valve actuation pressure is less than the difference between the pressure up stream of the pulse valve and a pilot within the poppet moves between disparate positions to modify fluid paths within the valve. When the valve is open, a relatively lower pressure is produced by a Venturi effect as the fluid flows through a throat in the poppet seat, to provide a differential pressure used to move the pilot and poppet.
