Wireless advantages

ADVANTAGES OVERVIEW

The operating advantages of cable-less seismic are well understood, but many contractors and oil companies don’t want to sacrifice data visibility.  That’s why we developed the industry’s only scalable, cable-free seismic data acquisition systems with real-time data return.  You can confirm the quality and fidelity of your data the moment you take a shot or initiate a sweep, and you never have to take an extra step to collect or transcribe the data.

FEATURES OF WIRELESS SEISMIC RealTIME

HYBRID RADIO TELEMETRY

HYBRID RADIO TELEMETRY: Enables your seismic data acquisition project to continue, uninterrupted, even if radio connectivity is temporarily lost for portions of the spread.  If radio connectivity is partially lost and auto skip-healing cannot overcome the immediate problem, then “stranded” recording units will immediately switch to operating autonomously, buffering their seismic data into local flash memory.  When radio connectivity is restored, buffered data are wirelessly transmitted back to the Central recorder.   Alternatively, autonomous recording can be user-selected at any time—where data will be buffered into local flash memory while real-time QC data continues to stream to the Central.

  • No complex data harvesters; data are transmitted to Central wirelessly.
  • No transcription trailers and related computer hardware.
  • No skilled field technicians required to transcribe data; data transmitted via the Hybrid Radio Telemetry system are aggregated automatically into the proper disk file, without manual intervention.
  • No “last patch” effect; no huge backlog of recording units to transcribe after the last shot is taken.
  • No need to purchase 10% to 15% more autonomous nodes to support data harvesting and/or battery charging functions.
  • No delayed decisions while waiting for data collection and transcription.

REAL-TIME NOISE MONITORING and QC

REAL-TIME NOISE MONITORING and QC:  Since noise and signal degradation can be monitored in real-time, there is no blind shooting, poor data quality, or loss of data due to box theft, damage, or software bugs.

REAL-TIME SEISMIC DATA COLLECTION

REAL-TIME SEISMIC DATA COLLECTION:  No need to wait to see your data; RT3 & RT2 are real-time, all the time.

SKIP HEALING TELEMETRY

SKIP HEALING TELEMETRY:  RT3 & RT2 are capable of automatically skipping over faulty units to reform the network, allowing shooting to continue while a crewman attends to the problem.

DYNAMIC FORMATION

DYNAMIC FORMATION:  Line segments self-organize, based on their location, reducing operator input errors and increasing deployment efficiency. Newly deployed units are automatically added to the end of the lines.

IMPORTANCE OF RealTIME IN CABLELESS ACQUISITION SYSTEMS

POWER & BATTERIES

WIRELESS SEISMIC SYSTEMS

  • Has smart batteries (the charging circuitry is in the battery) and a fuel gauge.
  • Smart batteries retain the history of each battery for analysis at any time.
  • Can check on the status of each battery on the spread.
  • Specially designed battery charger provides high-density charging with a small physical footprint.
MANAGEMENT & QUALITY CONTROL

WIRELESS SEISMIC SYSTEMS

  • Immediately lets the Observer know if there is a problem on the spread.
  • Lets the Observer view or QC the seismic data while it is recording.
  • Assures that the recorded data are safely stored at the central control system.
  • Lets the Observer interactively manage the spread (e.g., run daily tests, check battery status, run geophone tests, change shooting parameters, etc.).
  • Allows the Observer to “put the spread to sleep,” if needed, when unpredictable circumstances interfere with daily shooting.
  • Makes rolling onto a large 3D spread a relatively easy task.
COLLECTION & TRANSCRIPTION

WIRELESS SEISMIC SYSTEMS

  • Collects the recorded data in real time and saves it at the central recording system, where it can be transferred in industry-standard tape formats for processing.

As the demand increases for higher channel-count 3D surveys, to acquire more dense data, please consider that data download and transcription has been historically limited to less than 35,000 nodal channels. Will this process work at 100,000+ channels?
