Abstract

Summary

The need to improve resolution and quality of image of the complex structural geology in the Sub-Andean environments requires flexible acquisition systems due to the rough topography and limited access where heliportable support is mandatory.

The conventional cable systems limitations in channel count and heavy equipment generates an impact in the acquisition geometries and efficiency. The sparse geometries used as the most practical approach provided a coarse sampling, poor near surface information and irregular geophysical attributes in the seismic datasets.

The wireless nodal systems are valid alternatives for a higher channel count and better sampling because of their efficiency and operational flexibility over rough topography. These systems also represent safer conditions due to the reduction in equipment, people and exposure. Implementation of geophone arrays involves a lot of operational effort and HSE exposure in these terrains and its replacement to a single sensor acquisition is a desirable option.

This paper describes the first 3D seismic surveys acquired using high channel nodal system in two challenging Sub-Andean environments during 2014.
