SEISMIC DATA ACQUISITION SYSTEMS AND METHOD UTILIZING A WIRELINE REPEATER UNIT
First Claim
1. A system for acquiring seismic data, comprising:
- a source for generating acoustic signals into a subsurface of the earth;
a plurality of receivers placed in a selected region for detecting responsive acoustic signals from the subsurface;
a plurality of field station units (FSUs), wherein each field service unit (“
FSU”
) receives acoustic signals detected by at least one receiver associated therewith in the plurality of receivers, detects a condition for each of a plurality of attributes relating to acquisition of the seismic data, and transmits wirelessly a plurality of messages; and
a repeater unit that receives the plurality of messages from at least a group of FSUs in the plurality of FSUs and transmits information to a remote unit relating to the received messages.

Abstract
A system and methods for acquiring seismic data is provided. In one aspect, the system and methods utilize a plurality of field service units placed over a region of interest, a repeater unit that wirelessly communicates with the field service units and a remote unit for controlling and processing the seismic data acquired by the field service units. In one aspect, the system and methods determine a condition associated with each of a plurality of attributes relating to acquisition of the seismic data at each field service unit, generate messages at each field service unit when the condition of a particular attribute meets a selected criterion, transmit the generated messages, receive the messages transmitted by at least a group of field service units at a repeater unit placed in the region of interest, analyze the messages received from the group of field service units at the repeater unit and then transmit information relating to the received messages to the remote unit for further processing. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

10. A method for acquiring seismic data using a plurality of field service units (FSUs) placed over a region of interest, the method comprising:
-
determining a condition associated with each of a plurality of attributes relating to acquisition of the seismic data at each of the FSUs; generating messages at each FSU when the condition of a particular attribute meets a selected criterion; transmitting the generated messages; receiving the messages transmitted by at least a group of FSUs in the plurality of FSUs at a repeater unit placed in the region of interest; separating the messages received from the group of FSUs by the repeater unit into at least two categories based on at least one predefined limit in the repeater unit, wherein a first category of the at least two categories includes at least one message, which includes the condition that exceeds the at least one predefined limit; and transmitting information relating to the messages in the first category to a remote unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer-readable medium having a computer program embedded therein and accessible to a processor for executing the computer program, the processor being associated with a seismic data acquisition spread that includes a plurality of receivers for detecting acoustic signals and a plurality of field service units (FSUs), each FSU being associated with at least one receiver for acquiring and processing acoustic signals, wherein the computer program comprises:
-
instructions to determine a condition associated with each of a plurality of preselected attributes relating to acquisition of the seismic data by an FSU; instructions to generate messages at the FSU when the condition of any particular attribute meets a selected criterion; instructions to transmit the generated messages wirelessly; instructions to receive messages transmitted by at least a group of FSUs in the plurality of FSUs at a repeater unit placed in the region of interest; instructions to separate the messages received from the group of FSUs by the repeater unit into at least two categories based on at least one predefined limit in the repeater unit, wherein a first category of the at least two categories includes at least one message, which includes the condition that exceeds the at least one predefined limit; and instructions to transmit information relating to the messages in the first category to a remote unit. - View Dependent Claims (20, 21, 22, 23, 24, 25)
