Geophysical Survey and Hydrogeology

Before we drill, we study the ground. SC Nasser carries out, with its own resources, the geophysical survey that sites each borehole and the tests that prove its yield.

Vertical electrical sounding

We carry out vertical electrical sounding (VES) surveys to find the drilling points most likely to succeed. Each site gets a technical interpretation report that supports the choice of drilling point.

In-house team

SC Nasser geophysicists and test technicians follow each campaign, from the field survey to the report.

Pumping tests

We carry out step-drawdown and constant-rate pumping tests, with test sheets in the client's required format.
