Tailoring the energy source used for seismic acquisition surveys enables the desired imaging objective to be optimized. Typical energy sources contain an array of volumes to best match the geological environment.


A standard energy source array will produce an acoustic broadband output with frequencies peaking between about 6 to 200 Hz.

To expand the signal bandwidth for both lower and higher frequencies PXGEO is utilizing innovative source technologies.


Using these technologies allows significant extension of seismic signal bandwidth for ocean bottom node and towed streamer surveys.

Traditional use of marine sources required sequential activation of one or more sources as the survey vessel progressed down a selected acquisition line so that reflected signals from successive shots did not interfere.

With the recent development of robust data processing source de-blending techniques, multiple sources can now be activated in blended modes including overlapping in time or activated simultaneously. The use of blended multiple source techniques significantly increases 3D spatial sampling and trace densities while enhancing overall survey efficiencies.

PXGEO has a wide range of experience in towed streamer and ocean bottom node survey designs using blended energy source techniques.

PXGEO's multiple source, XArray™ configurations provide improved in-line shot intervals and cross-line bin density on any streamer separation. These can be tailored to provide higher fold data, increase cross line sampling and/or improve acquisition efficiency.

This is achieved using multiple sources, continuous data recording and ‘deblending’ algorithms to separate energy from overlapping shots.
