The targeted drilling performed during the construction through the Río Grande river, became a world record for its characteristics: 23 meter deep, 2000 meter length, for a 32 inch pipeline.

The drilling sequence started-up with a driving hole controlling the necessary direction to follow-up the previously established trajectory, continuing with the drilling hole widening.

The calculations, calculations memory and traction and torsion effort analysis, as well as the admissible bent curve for the pipeline during the pull-back were performed previously to the design of the necessary area, and the mounting of the pipeline section, with its hydrostatic test to finally run the pull-back operation.
