Infinity Seismic RFID-enables Its Geophone Testers

The company's CheckMate Land handheld device is available with an RFID reader, to automatically identify the testing of geophones used by the oil and gas industry in measuring seismic activity.

Jun 25, 2012Infinity Seismic, a division of electronics development company Divercety, has released an RFID-enabled solution for testing the geophones used by the oil and gas industry to pinpoint appropriate drilling sites. With a passive low-frequency (LF) radio frequency identification tag attached to each string of seismic-testing geophones, as well as an RFID reader plugged into Infinity Seismic's testing equipment, oil and gas companies can better track the results of every test performed on each piece of equipment—and do so in less time than would be required to manually input the ID number of each string being tested—in order to create a record of that testing.

The solution's research and development was done by Vercét, a sister company to Divercety.

To conduct a site survey, a company typically places strings of up to 15 geophones on the surface of the ground, where they can then measure ground movements and convert them into electronic signals with frequencies ranging from 1 Hz to 100 Hz. By searching for deviations in the readings, a geophone user can determine where a potential oil well could be drilled successfully.

Infinity Seismic now offers an RFID reader that plugs into its Land CheckMate geophone tester.
Infinity Seismic manufactures geophysical test equipment, including the CheckMate Land unit, which conducts tests to ensure that geophones are operating properly. To ensure that all geophones on a particular string remain in good working order, each geophone is tested independently, and the results must be recorded by those undertaking the tests. Such testing must be conducted as frequently as once a month. For geophone users, this can mean running tests on many hundreds of strings daily.

Tests are often undertaken at oil and gas base camps. Each string of geophones undergoes a test lasting 10 to 20 seconds, in order to ensure that every geophone is functioning properly before it is put into service by a drilling company, or by a seismic-testing firm working for an oil driller.

With a non-RFID CheckMate Land device, a user must manually key a string's serial number into the testing unit every time that string is tested. When a large quantity of geophone strings must be tested, inputting every string's serial number—to be stored in the testing unit's software—can be time-consuming and result in errors if the wrong numbers are keyed in. With RFID, the inputting of each string's unique identifier becomes automatic.
