Device for holding seismic nodes during a seismic survey
A recently filed patent (Publication Number: US20230288596A1) describes a device for holding seismic nodes during a seismic survey. The device includes a body with an outer surface that can be seated against the ground during the survey. It also has multiple receptacles extending vertically from the top side of the outer surface, as well as a second receptacle extending from the outer surface into the body. The central axes of the receptacles are oriented vertically and parallel to each other, with a reference plane perpendicular to the central axis of the second receptacle.
The device may also include a third receptacle, with a second reference plane perpendicular to the central axis of the third receptacle. The first and second reference planes are oriented perpendicular to each other. Each receptacle is designed to receive a seismic node or a weight blank. The central axis of the second receptacle is horizontally oriented. The outer surface of the body includes lateral sides, with the first receptacle extending perpendicularly from the top side and the second receptacle extending perpendicularly from one of the lateral sides.
The patent also describes a seismic node assembly for detecting and measuring seismic signals during a seismic survey. The assembly includes the aforementioned device for holding seismic nodes, as well as a first seismic node removably seated in the first receptacle and a second seismic node removably seated in the second receptacle. Each seismic node operates independently and is not electrically coupled to any other device during the survey. The outer surface of the body includes lateral sides, with the second receptacle extending horizontally from one of the lateral sides and the second seismic node having a horizontally oriented central axis.
The method for deploying the seismic nodes involves loading the first and second seismic nodes into their respective receptacles, positioning the body of the holding device against the ground, and detecting and measuring P-waves and shear waves with the first and second seismic nodes, respectively. Each seismic node operates independently and is not electrically coupled to any other device during the detection and measurement process. The method may also involve adding ballast material to the holding device to increase the weight of the seismic node assembly and relying on the weight to maintain the position and orientation of the first seismic node.
