A method of performing a seismic survey including: deploying nodal seismic sensors at positions in a survey region; activating a plurality of seismic sources; and using the nodal seismic sensors to record seismic signals generated in response to the activation of the plurality of signals.

The present disclosure is directed to systems and methods of facilitating a seismic survey and locating seismic data acquisition units in a marine environment. The system can include a first seismic data acquisition unit. The first seismic data can include a cleat ring to couple the first seismic data acquisition with a second seismic data acquisition unit. The system can include a rope having a first end coupled to a first portion of the first seismic data acquisition unit and a second end coupled to a second portion of the first seismic data acquisition unit. The system can include a cavity formed by the cleat ring. The system can include a telltale component coupled to a portion of the rope. The rope and the telltale component can be stored in the cavity of the first seismic data acquisition unit.

An automated storage and retrieval system for seismic nodes includes a modular housing having a first row of rack structures and a second row of rack structures. The system further includes a first receptacle configured to couple a sensor module of a seismic node to a rack structure of the first row of rack structures for storage and reconditioning of the sensor module, and a second receptacle configured to couple a power source module of the seismic node to a rack structure of the second row of rack structures for storage and reconditioning of the power source module.

A marine seismic exploration method and system comprised of continuous recording, self-contained ocean bottom pods characterized by low profile casings. An external bumper is provided to promote ocean bottom coupling and prevent fishing net entrapment. Pods are tethered together with flexible, non-rigid, non-conducting cable used to control pod deployment. Pods are deployed and retrieved from a boat deck configured to have a storage system and a handling system to attach pods to cable on-the-fly. The storage system is a juke box configuration of slots wherein individual pods are randomly stored in the slots to permit data extraction, charging, testing and synchronizing without opening the pods. A pod may include an inertial navigation system to determine ocean floor location and a rubidium clock for timing. The system includes mathematical gimballing. The cable may include shear couplings designed to automatically shear apart if a certain level of cable tension is reached.

A system and method for a distributed earthquake analysis and reporting system are provided. The system includes a facility control system at a facility that obtains earthquake information sent from one or more seismic sensors, and sends the earthquake information over a network directly or indirectly to other facility control systems. The facilities which include the facility control systems can be owned/operated by different business organizations or by the same organization, in examples. The facility control system at each facility responds to received earthquake information from the other facility control systems by configuring building systems such as public address systems to warn building occupants, industrial machine controllers to stop machinery, and elevator controllers to stop elevators at a nearest floor and open its doors, in examples.

Methods, systems, and devices for conducting a seismic survey. The system includes a seismic sensor supplying a seismic signal; sampling circuitry configured to convert the signal to a sequence of samples, each sample represented by a bit string; a data communication device configured to transmit compressed seismic data; a recording computer configured to receive compressed seismic data; at least one processor with a computer memory accessible thereto, the at least one processor configured to: create a sample block by storing at least a portion of the sequence of samples in memory units in the computer memory, wherein each sample is stored in a corresponding memory unit; and compress data contained in the sample block by encoding all bits of a particular bit number from the memory units of the sample block in sequence to produce compressed seismic data.

A marine seismic data acquisition system and method of conducting a marine seismic survey are disclosed. The system incorporates one or more surface vessels, and a plurality of autonomous nodes for acquiring seismic data at one or more seabed locations. Each node comprises a USBL, SSBL or SBL transducer and USBL, SSBL or SBL acoustic modem. A first acoustic positioning system is operable between one of the surface vessels and the nodes, the first acoustic positioning system being a USBL, SSBL or SBL system. Each node of the plurality of autonomous nodes has a USBL, SSBL or SBL beacon address, with respective groups of nodes having the same beacon address. The nodes are configured such that no two nodes with the same beacon address can actively communicate over an associated USBL, SSBL or SBL modem at the same time.

A method includes obtaining a digital seismic file, performing autodetection of parameters of the digital seismic file, and registering the parameters of the digital seismic file with the digital seismic file. Performing autodetection comprises a computer processor, repetitively until a candidate template successfully extracts the parameters, selecting a target candidate template, attempting extraction of a binary header using the target candidate template, attempting extraction of a trace header using the target candidate template, attempting extraction of the plurality of parameters when the target candidate template extracts the binary header and the trace header, and moving to a next target candidate template when extraction of the plurality of headers is unsuccessful.
