International Classification:

G01V 122

US Classification:

367 13, 367 76

Abstract:

The present invention provides a method and apparatus of acquiring and processing seismic data. One or more controllers are each coupled to seismic sensors and to each other to form a line of data acquisition units. A main controller is coupled to a crossover line unit and to a power supply. Power and data control is distributed among the main controller, the crossover line unit, and each of the plurality of data acquisition units.

International Classification:

G01V 1/00
H01R 9/03

US Classification:

367 76, 439620, 439624, 439638

Abstract:

A seismic data acquisition system includes a connector housing and a mating electrical circuitry module. A single interface couples electrical circuitry housed in the electrical circuitry module to one or more signal data carriers that are consolidated at a single location in the connector housing. Preferably, the connector housing and electrical circuitry module each have a substantially contaminant-free interior regardless of whether these two parts are mated. An alternate connector housing has two plug casings, each of which are provided with a plug. A complementary alternate electrical circuitry module includes two receptacles complementary to the plugs and an interior space for holding the electrical circuitry. A locking pin disposed within the plug casing selectively engages the electrical circuitry module. A method for establishing communication between electrical circuitry and the carriers and external devices includes providing a single communication interface between the carrier and the electrical circuitry.

International Classification:

G01V001/00

US Classification:

367/014000, 340/856400

Abstract:

A two-conductor bidirectional digital telemetry interface between a seismic sensor acquisition/conversion module and a seismic data collection module. The data collection module is configured as a master electronics device and the sensor acquisition/conversion module is configured as a slave electronics device in the telemetry system. The master device provides power to the slave device over the two conductors. The master device transmits portions of commands to the slave device at a first time and the slave device transmits portions of a digital seismic data packet to the master at a different second time in a fixed-duration frame. The frames are transmitted at regular intervals. The outbound commands and inbound data are encoded by block codes. A phase-locked loop in the slave is locked to a master clock in the master by deriving a clock and a sync point from the block-coded commands it receives from the master. The block code representing each command bit minimizes dc drift and provides a level transition in the command that can be used to maintain synchronism between master and slave.

G01V 1/16

Abstract:

In one aspect, a seismic data acquisition unit is disclosed including a closed housing containing: a seismic sensor; a processor operatively coupled to the seismic sensor; a memory operatively coupled to the processor to record seismic data from the sensor; and a power source configured to power the sensor, processor and memory. The sensor, processor, memory and power source are configured to be assemble as an operable unit in the absence of the closed housing.
