DSU include 9,250 DSUGPS stakeless three-component (3-C) digital sensors for dry land operations and 750 DSU3BV buried version digital sensor units for transition zone operations.
Comesa, which has been equipping its land acquisition crews with Sercel 408, 428XL and Unite cable-free acquisition systems since 2002, has now added the DSUGPS system to its list of Sercel equipment, the company said.
The DSUGPS integrates two GPS antennas, enabling it to calculate both the DSU position and sensor azimuth within the recorded data, which is vital to 3-C applications.
Sercel CEO Pascal Rouiller said that the DSUGPS and DSU3 provide the most effective operational system in the industry using MEMS-based digital sensor units.
Sercel is a designer and manufacturer of seismic equipment and reservoir monitoring instruments.
