INOVA proudly represents the durable, low-maintenance AHV-IV family of vibrators with the latest advances in source technology implemented in the industry standard Articulated Hydrostatic Vehicle (AHV) design.
A variety of configurations and a comprehensive selection of customizable options are avaiable on our AHV-IV product line to accommodate variations in terrain, environment, or imaging requirements.
INOVA offers two options to meet imaging and operational requirements in the form of different actuators( PLS-364 and PLS-380). Also available are customizable features such as a winter package for arctic environments and standard or heavy-duty tracks for loose impediment and icy conditions
Harmonic Distortion Reduction - Turned On
Ensuring P-wave propagation and high-force energy penetration in a variety of terrains is our first priority when implementing new vib technology or design changes to our AHV-IV Commander and Renegade vibrators. Vibrator mechanics, maintenance and sweep design can negatively impact seismic imaging if the vehicles are not operated properly during acquisition.
If your imaging goal is waveform inversion model building (Baeten, 2013) or structural analysis that requires wavelet sharpness (Denis, 2013), the AHV-IV is the best broadband vibrator for the survey. Most conventional vibrators can’t deliver enough energy at the lower frequency range, however the AHV-IV has a 2.5x stiffer baseplate and a hydraulic flow system that reduces harmonic distortion and improves signal penetration.
Anyone who’s spent time maintaining a vib fleet knows how mechanical failures and downtime can delay a seismic acquisition program - delays that are costly to both the geophysical contractor and the E&P operator. The ability to easily diagnose and fix problems in the field is essential, but more importantly, reliability and uptime are the primary reasons why the AHV-IV class of vibrators is still #1 in the industry.
With more than 1800 in operation around the world and a rich history that dates back to 1970 with the introduction of the very first AHV vibrator (under Litton Resources Services aka LRS), the AHV-IV product line is still known for its dependability and durability today.
All INOVA systems contain a robust software called iX1 that consolidates source control and spread management into one simplified view for the Party Chief. Managing and visualizing source operations on a single system ensures higher quality imaging through better QC so you never miss a sweep.Learn More

What does it all mean? Vibroseis terms can be confusing, and there are many terms used in seismic acquisition today. This is exacerbated by the fact that, in some instances, the same term is used with a different meaning depending on the context it is being applied. Our team here at INOVA discuss vibroseis terminology and explains terms like fundamental ground force and peak ground force as well as other common terms used today.
