Peru 2012

Geophysical maintenance of hydrogeological survey in Peru, 2012

West Coast of the continent, near-shore zone. Area of rock withdrawal from intermountain trough.

Survey procedure:

  • Method TDEM,
  • equipment Tsikl 7
  • Coaxial sounding configuration: 50х50 m transmitter loop, receiver of 2 500 sq.m moment.
  • 200 m spacing along line.
  • Peak current in transmitter loop – 17 А

Taking into account both well data and the SECOND layer resistivity, one would expect this layer is a source of fresh water, which was borne out by subsequent drilling data. Underlying deposits of low resistivity are argillaceous and serve as an aquiclude
