Abstract: Seismic survey systems and methods that utilize a source event schedule to autonomously generate source events with reference to a reference clock. In this regard, a source event controller may be employed that is synchronized to a reference clock to generate source events with respect to the source event schedule and without requiring real time two way communication between an encoder and a decoder. Accordingly, source events may be generated at a known time even in terrains and environments where real time communication between an encoder and decoder are impractical or impossible.

Abstract: Systems and methods for seismic data acquisition with location aware network nodes. Based on location information of the nodes of the network, a multiplexing signature may be provided for the node. The location information may be used in conjunction with other information (e.g., location information of other nodes in the network and transmission ranges for nodes in the network) to determine collision domains. A multiplexing signature may be assigned to a node based on information regarding a collision domain to which the node belongs. As such, the assigned multiplexing signature may be used to avoid data collisions.

Abstract: Presented are systems and methods for deploying wireless data acquisition modules that facilitate autonomous initialization. The wireless data acquisition modules may initiate a initialization process in response to a stimulus associated with being deployed. The wireless data acquisition module may further conduct a neighbor discovery process and in turn establish a data transfer path among one or more other wireless data acquisition modules. Further, information obtained during a series of autonomous tests may be communicated during the neighbor discovery process and the establishment of the data transfer path may at least in part be based on the information obtained in the autonomous tests.

Abstract: Systems and methods are provided for acquiring seismic data using a wireless network and a number of individual data acquisition modules that are configured to collect seismic data and forward data to a central recording and control system. In one implementation, a number of remote modules (301) are arranged in lines. Base station modules (302) receive information from the lines and relay the information to a central control and recording system (303). Radio links operating on multiple frequencies (F1-F12) are used by the modules (301). For improved data transfer rate, radio links from a remote module (301) leap past the nearest remote module to the next module closer to the base station.

Abstract: A data collection system that is operable to read out seismic data collected at wireless acquisition modules in response to source events such that the progression of subsequent source events occurs prior to the complete data record for a prior source event being collected at a data collection unit. The system may include mechanisms by which the source event progression is only interrupted based on a detected potential for loss of data integrity.

Abstract: Data acquisition modules and systems including batteries with integrated data storage. The battery with integrated data storage can be selectively removed from the data acquisition module. This allows for reduced logistical effort associated with data retrieval and battery charging. For instance, the entire data acquisition module need not be transported to a central location for data recovery and charging, but rather the removable battery with integrated storage may be removed and transported. Also facilitated is extended surveys in that the battery or storage module may be replaced, such that survey design limitations such as storage capacity or battery life may be eliminated.

Abstract: Systems and methods for seismic data acquisition employing a dynamic multiplexing technique. The dynamic multiplexing technique may include advancing one or more modules in a seismic array through a multiplexing signature sequence in successive transmission periods. The multiplexing signature sequence may be random or pseudo-random. A shared multiplexing signature sequence may be used at all the modules in the seismic array. As such, modules belonging to a common collision domain may operate out of phase with respect to the shared multiplexing signature sequence.

The synchronized data acquisition array may be used to facilitate a seismic survey. Synchronization may be facilitated by receipt of a reference time event such that a clock is synchronized based on the reference time event.

The shared multiplexing signature sequence may include, among others, a plurality of different frequencies, a plurality of different codes, or a plurality of different discrete time periods.
