Advanced Seismic Source
GI-SOURCE
Sercel developed the GI-SOURCE to reduce and suppress the bubble oscillation from a single impulsive source to simplify processing. The GI-SOURCE impulsive source is based on the same technology as the GI-SOURCE but is different in that it has two independent air chambers within the same casing : the Generator (generating the primary pulse and creating the main bubble) and the Injector (injecting air inside the main bubble so that it collapses quickly).

Seismic Sensors & Transducers
Displacement Pickups are vibration transducers that incorporate a spring-mass system with eddy-current damping using a frictionless pivot. This pivot is a spring flexure that serves as the ‘spring’ and a moment arm attached to the pivot serves as the ‘mass’, which allows resolutions down to the micro inch range. At frequencies above 50Hz, the mass remains fixed in space and becomes an inertial reference. A transducer within the pickup senses the motion of the mounting base relative to the inertial reference and converts it into a proportional signal. Appropriate damping results in a frequency response flat down to 10 Hz. Note that the pickup senses in only one plane, which is perpendicular to the mounting base.

Test Analysis for Land Seismic Systems
Testif-i Land
Testif-i Land is an independent, powerful and cost effective software suite that allows you independently process instruments, source and receiver tests to confirm that the equipment is performing correctly and within specification. The software includes modules to perform comprehensive analysis of vibrator wireline similarity test data. Analysis includes a harmonic intensity plot which can highlight problems such as sub-harmonics which may not be seen on numerical results. Geophone pulse tests can be analysed using the receiver response module and test data from third party geophone testers can be graphed and statistics produced for ease of interpretation.

Seismic Vibration
Seismic vibration instrumentation is used to measure structural vibration on bearing housings, piping, machinery housings, and machine support structures. It is particularly suitable for machinery with rolling-element bearings. These types of bearings will generally transmit both shaft-and bearing-related vibration to the outside of the machine where it can be detected by seismic measurements.

Radio Trigger Module
RTM3
The Remote Trigger Module 3, or RTM3 3, is a new generation of impact trigger device. It is designed to time synchronize a single seismic source unit with multiple seismic recorders. It can also be used to synchronize multiple seismic recorders. The RTM3 units use an internal high accuracy oscillator that is synchronized to GPS timing information. Each RTM3 unit requires an external GPS receiver with valid satellite information to synchronize the internal clock. Once the internal clock is synchronized the RTM3 can be used without any GPS signal for up to 10 minutes.
