Adding XHR to your primary OBS survey is a lower-cost approach to a higher-density dataset.

A perfect pairing for nodes, PRM, DAS or VSP.

To build trace density, economics typically dictates that ocean bottom seismic (OBS) surveys rely on relatively dense source carpets to compensate for the less-dense receiver grids. This means your source vessel goes everywhere, even beyond the edge of the receiver footprint. By adding XHR cables to the source vessel, XHR OBS from Magseis Fairfield lets you build a high-density XHR dataset to complement the OBS dataset being simultaneously acquired.

Combined with the primary survey — via nodes, PRM, DAS or VSP — this additional XHR OBS dataset has a range of useful applications. For nodes and PRM, it can supplement the near-offset data lost with wider node spacing as well as extend the near-offset rich 3D dataset to the edge of the source halo. For DAS and VSP, it is added to the downhole dataset.

Augment your data, not your risk.

An economically attractive addition to your primary survey, XHR OBS can also provide a one-stop data solution by eliminating the requirement and exposure of a dedicated site survey.
