Abstract
A marine seismic acquisition system includes a frame that includes a central longitudinal axis and members that define orthogonal planes that intersect along the central longitudinal axis; a data interface operatively coupled to the frame; hydrophones operatively coupled to the frame; a buoyancy engine operatively coupled to the frame where the buoyancy engine includes at least one mechanism that controls buoyancy of at least the frame, the hydrophones and the buoyancy engine; and at least one inertial motion sensor operatively coupled to the frame that generates frame orientation data, where the hydrophones, the buoyancy engine and the at least one inertial motion sensor are operatively coupled to the data interface.
Claims17
A system, comprising:
- a sensor array configured to couple to a vessel, wherein the sensor array comprises:
- at least three members arranged parallel to each other and configured to form a triangular prism shape, wherein the at least three members are configured to be positioned in a vertical position while underwater;
- and
- a plurality of seismic sensors mounted to each of the at least three members;
- and
- at least two components configured to maintain a buoyancy of the sensor array while underwater at a depth, wherein the at least two components comprise:
- a first collar configured to couple to each of the at least three members at a first position, wherein the first collar forms a circular shape, and wherein the triangular prism shape is positioned within the first collar;
- and
- a second collar configured to couple to each of the at least three members at a second position opposite the first position, wherein the second collar forms the circular shape, and wherein the triangular prism shape is positioned within the second collar.
A seismic acquisition system, comprising:
- a vessel;
- a sensor array configured to be coupled to the vessel via a cord, wherein the sensor array comprises:
- at least three members arranged parallel to each other and configured to form a triangular prism shape, wherein the at least three members are configured to be positioned in a vertical position while underwater;
- a plurality of seismic sensors mounted to each of the at least three members;
- and
- at least two components configured to maintain a buoyancy of the sensor array while underwater at a depth, wherein the at least two components comprise:
- a first collar configured to couple to each of the at least three members at a first position, wherein the first collar forms a circular shape, and wherein the triangular prism shape is positioned within the first collar;
- and
- a second collar configured to couple to each of the at least three members at a second position opposite the first position, wherein the second collar forms the circular shape, and wherein the triangular prism shape is positioned within the second collar.
A sensor system, comprising:
- a sensor array configured to couple to a vessel, wherein the sensor array comprises:
- a first member, a second member, and a third member arranged parallel to each other and configured to form a triangular prism shape, wherein the first member, the second member, and the third member are configured to be positioned in a vertical position while underwater;
- and
- a plurality of seismic sensors mounted to each of the first member, the second member, and the third member;
- and
- a first component and a second component coupled to the sensor array and configured to maintain a buoyancy of the sensor array while underwater at a depth, wherein the first component is configured to couple to the first member, the second member, and the third member at a first position, wherein the first component forms a circular shape, wherein the triangular prism shape is positioned within the first component, wherein the second component is configured to couple to the first member, the second member, and the third member at a second position opposite the first position, wherein the second component forms the circular shape, and wherein the triangular prism shape is positioned within the second component.
